Privacy Policy

Effective: May 12, 2026

​

DC Math and Martial Science Club, LLC (hereafter called "DC Math and Martial Science Club, LLC" "us" or "we") knows that you care how information about you is used and shared, and we appreciate your trust that we will do so carefully and sensibly. This Privacy Policy describes our collection and use of personal information collected from you through the online and/or mobile services, websites, and software provided on or in connection with www.dcmathandmartialscienceclub.com (collectively, the "Service"), which are offered through (i) www.dcmathandmartialscienceclub.com, (ii) mobile applications associated with www.dcmathandmartialscienceclub.com, and (iii) any other DC Math and Martial Science Club, LLC website, app or online service which links to this Privacy Policy. "You" or "your" means a visitor or a user (whether signed in or not) of our Service. Your use of the Service is conditioned on your acceptance of this Policy.

A note about Student Data: This Service may be purchased by providers of educational services, such as schools, school districts, or teachers (collectively referred to as "Schools") that use our services for educational purposes. When DC Math and Martial Science Club, LLC contracts with a School to provide the Service, we may collect or have access to Student Data (defined below), which may be provided by the School or by the student. We consider such Student Data to be strictly confidential and in general do not use such data for any purpose other than improving and providing our Services to the School or on the school's behalf. Our collection, use and sharing of Student Data is governed by our contracts with the School and any applicable laws and regulations including, in the U.S., provisions of the Family Educational Rights and Privacy Act ("FERPA"), the Children's Online Privacy Protection Act ("COPPA") and applicable state laws, including without limitation the Illinois Student Online Personal Protection Act (SOPPA). If you have any questions about reviewing, modifying, or deleting personal information of a student, please contact your School directly. See Section 11 to understand the principles which guide our collection, use and disclosure of Student Data.

1. What information does DC Math and Martial Science Club, LLC collect about you?

​

DC Math and Martial Science Club, LLC collects information in several ways from different parts of the Service.

Information you provide to us. The type of personal information we collect may vary depending on your account type.

• School Information. When a teacher, school administrator, or other authorized person associated with a School registers for an account on our Service or corresponds with us, we may collect personal information such as a name, e-mail address, payment information, username and password, and information about the School.

• Student Information. Once registered, a School may provide information about its students, such as student names or other identifiers, passwords, e-mail address for the student or the student's parent or legal guardian, and educational level and topic of study. Personal information collected from or about students, along with other information associated with that personal information is "Student Data." The School may elect to provide user names or identifiers which are not readily identifiable to anyone outside of the School community in lieu of a full student name, at its discretion. Additionally, some Schools may elect to use a single-sign on (SSO) service like G Suite for Education rather than usernames and passwords to authenticate student access.

• Parent and Child Information. When a parent or guardian ("Parent") registers for an account on our Service or corresponds with us, we may collect personal information such as a name, e-mail address, payment information, username and password. We may also collect information about the child(ren) authorized by the Parent to use the Service through the Parent's account, including a profile name for the child user and selection of a profile avatar. Each child user profile must be associated with a Parent account, and children cannot access the Service without the Parent first signing in to the Parent account with the Parent's sign in credentials.

• Learning and Activity Information. During the course of providing the Service, we collect information about your use of the Service, as well as any information that you submit to the Service, such as answers to questions or content or messages posted or shared through the Service. In addition, we may ask you for personal information at other times, such as when you contact our technical support team, send us an e-mail, complete a user survey or otherwise communicate with DC Math and Martial Science Club, LLC.

Information we receive automatically from your use of our Service. Like most websites and online services,DC Math and Martial Science Club, LLC and our vendors automatically collect certain types of usage information when you visit www.dcmathandmartialscienceclub.com, read our e-mails, use our Service or otherwise engage with us. This information is typically collected through a variety of tracking technologies, including cookies, web beacons, Locally Stored Objects (LSOs such as Flash or HTML5), log files, and similar technology (collectively, "tracking technologies"), and we may use third party providers to collect this information on our behalf. These tracking technologies collect information about how you access and use the Service (e.g., referring / exit pages and URLs, how frequently you access the Service, the pages you view, the links you click, and other actions you take on the Service); information about your browser and information about the device(s) you use to access the Service (e.g., Internet Protocol (IP address), browser type, browser language, Internet service provider, device type, model and manufacturer, a unique ID that allows us to uniquely identify your browser, device or account, operating system brand and model, and whether you access the Service from multiple devices). We may also collect information about your geographical location data at the city level. We may collect analytics data, or use third-party analytics tools, such as Google Analytics, to help us measure traffic and usage trends for the Service and to understand more about the demographics and behaviors of our users. You can learn more about Google's practices at http://www.google.com/policies/privacy/partners. We may also work with third party partners to employ technologies, including the application of statistical modeling tools, which permit us to recognize and contact you across multiple devices. Although we do our best to honor the privacy preferences of our users, we are unable to respond to Do Not Track signals set by your browser at this time.

We use or may use the data collected through tracking technologies to secure the Service, improve the Service, to save you time, to provide better technical support, for promotional purposes, and to track website usage. For example, tracking technologies help us to:

1. Keep track of whether you are signed in or have previously signed in so that we can display all the features that are available to you.

2. Remember your settings on the pages you visit, so that we can display your preferred content the next time you visit.

3. Customize the function and appearance of the pages you visit based on information relating to your account; for example, to default you to a particular grade level, or to remember customized settings for a report.

4. Track website usage for various purposes including website optimization, website improvement, sales, marketing, and billing.

Most browsers are initially set up to accept cookies, but you can reset your browser to refuse all cookies or to indicate when a cookie is being sent. However, some features and services (particularly those that require you to sign in) may not function properly if your cookies are disabled. You may also set your e-mail options to prevent the automatic downloading of images that may contain technologies that would allow us to know whether you have accessed our e-mail and performed certain functions with it. Deleting cookies does not prevent the collection of information through non-cookie technologies and does delete Local Storage Objects (LSOs) such as Flash objects and HTML5. You can learn more about Flash objects — including how to manage privacy and storage settings for Flash cookies — on Adobe's website. If you choose to delete Flash objects from our sites, then you may not be able to access and use all or part of the sites or benefit from the information and services offered.

We and our third-party partners may also use cookies and tracking technologies for advertising purposes. For more information about tracking technologies, please see "Third-party tracking and online advertising" below.

​

3. How does DC Math and Martial Science Club, LLC share your information?

​

DC Math and Martial Science Club, LLC may share or disclose your personal information as needed to provide our Service or with your consent or permission. We may also share personal information in the circumstances described below.

Third parties with Consent or as Instructed We share information with consent and at the direction of Schools and Parents. For example, a School or Parent may direct DC Math and Martial Science Club, LLC to share specific information with another individual, such as when a teacher directs DC Math and Martial Science Club, LLC to send a communication to a parent. Similarly, we may share personal information with third parties, for example, if a School authorizes Google login or similar authentication tools for that School's user accounts.

Others within the School. DC Math and Martial Science Club, LLC may share information collected from users associated with a School with other users or persons designated by the School, such as teachers and school administrators of that School. Messages and content shared or posted by members of a School community, such as messages between a teacher and students in a class, will be accessible by School administrators or other designated School users.

Vendors and Service Providers. DC Math and Martial Science Club, LLC may share information with our trusted vendors, third party service providers and individuals to provide services or products for us or on our behalf, which may include analytics, hosting, billing, targeted advertising, and marketing (provided however, that DC Math and Martial Science Club, LLC will not knowingly use any Student Data to target advertising or marketing). Vendors and service providers who have access to Student Data, if any, shall be contractually bound to uphold privacy and confidentiality terms no less protective than those provided herein.

Aggregate or De-Identified Information. We may share information in aggregated and/or anonymous form that cannot reasonably be used to identify an individual. For example, DC Math and Martial Science Club, LLC may disclose aggregated user statistics (i.e., the total number or percentage of DC Math and Martial Science Club, LLC users from a particular geographic region) in order to describe our Service to current and prospective partners and other third parties, and for other lawful purposes.

Merger or Sale. If DC Math and Martial Science Club, LLC becomes involved in a merger, acquisition, bankruptcy, change of control, or any form of sale of some or all of its assets, your personal information may be transferred or disclosed in connection with the business transaction. In such an event, we will make efforts to provide notice before personal information is transferred and becomes subject to a different privacy policy. We will not transfer Student Data associated with School accounts in the event of a merger or sale unless the recipient has committed to The Student Privacy Pledge principles or similarly stringent privacy protections, or we will provide Schools with notice and an opportunity to opt-out of the transfer of Student Data by terminating their accounts and any associated student users before the transfer occurs.

Other. DC Math and Martial Science Club, LLC may release personal information if it has a good faith belief that access, use, preservation, or disclosure of such information is reasonably necessary to (a) satisfy any applicable law, regulation, legal process, or enforceable governmental request; (b) enforce applicable Terms of Service, including investigation of potential violations thereof; (c) detect, prevent or otherwise address fraud, security or technical issues; (d) protect the rights, property, or personal safety of DC Math and Martial Science Club, LLC, its users, or the public; or (e) as required or permitted by law.

​

4. Third-party tracking and online advertising

​

DC Math and Martial Science Club, LLC does not display any targeted advertising on the Service.

Please note that although we may permit third party advertising partners to collect information from visitors to adult-directed areas of the Service for the purpose of displaying advertisements on other websites or online services on our behalf, we take many steps to prevent these third-party advertising networks from collecting information for targeted advertising purposes once a subscriber to our Service signs into our Service. Please note that we rely on cookies to identify whether you are a subscriber to our Service and if you delete or block cookies, you may also delete the DC Math and Martial Science Club, LLC cookie which prevents subscribers from receiving targeted DC Math and Martial Science Club, LLC advertisements on other websites or online services.

We work with third-party online advertising networks which use technology to recognize your browser or device and to collect certain types of usage information about your visit to or use of our Service to provide customized content, advertising and commercial messages to you on other websites or services, or on other devices you may use. We (through the third-party advertising networks) use this information to direct our online advertisements to those people who may find them relevant to their interests. Typically, though not always, the information is collected through cookies or similar tracking technologies. You may be able to set your browser to reject cookies or other tracking technology by actively managing the settings on your browser or mobile device, though these tools may not be effective for all third-party tracking technologies, including Flash or HTML5 cookies. To learn more about cookies, clear gifs/web beacons and online advertising technologies and how you may opt-out of some of this advertising, you may wish to visit the Digital Advertising Alliance's resources at www.aboutads.info/choices and/or the Network Advertising Initiative's online resources, at www.networkadvertising.org.

If you do not want to receive targeted advertising from DC Math and Martial Science Club, LLC based on your visit to our website, you can use the below link to request that DC Math and Martial Science Club, LLC take steps to prevent third-party advertising networks from using information about your visit to our website to display targeted DC Math and Martial Science Club, LLC advertisements to you on other websites or services on behalf of DC Math and Martial Science Club, LLC. DC Math and Martial Science Club, LLC cannot, however, guarantee that such steps will eliminate all collection and/or display of targeted advertising, and it may take some time for your request to take effect. Such requests will not prevent you from receiving contextual advertising or other types of advertisements that are displayed without taking into consideration whether you have previously visited dcmathandmartialscience.com for example, advertisements shown on the basis of a search term keyword). Such requests will not stop the collection of information for purposes other than advertising (e.g., for website analytics). This opt-out requires the setting of a cookie in your browser to record your request (and thus will no longer be effective if the required cookie is deleted), will be effective only in the browser from which you make the request, and will be effective for a maximum of one year from the request. If you delete cookies, change your browser settings, switch browsers or computers, or use another operating system, you will need to make the request again. You may make additional requests at any time. Contact us to request not to be tracked.

5. How to control e-mail communications

​

If you are a parent or guardian of a student who uses the DC Math and Martial Science Club, LLC Service through a School, please refer all questions and requests regarding access, modification, or deletion of your student's user account or Student Data to your child's school. The School may, at its discretion, address such requests with DC Math and Martial Science Club, LLC and DC Math and Martial Science Club, LLC shall respond promptly to all access, modification and deletion requests it receives from Schools.

Please contact us for further instructions about deleting or deactivating your account or deleting your personal information. We may not be able to comply with your request in all circumstances. For example, certain requests to access, update or delete personal information and data associated with a School account or license may be subject to approval by the School. When account information is deleted or de-identified, certain residual information may remain within our archive records, such as for customer and technical support, billing and tax purposes.

​

7. How long does DC Math and Martial Science Club, LLC retain your information?

We will retain personal information for as long as needed to provide the Service and for our internal business purposes, which may extend beyond the termination or cancellation of your subscription or user account. For example, we may retain certain data as necessary to prevent fraud or future abuse, for record keeping or other legitimate business purposes, or if required by law. We may also retain and use information which has been de-identified or aggregated such that it can no longer reasonably identify a particular individual. All retained personal information will remain subject to the terms of this Privacy Policy.

Student Data. We will not knowingly retain Student Data beyond the time period required to support an educational purpose, unless authorized by a School or parent. We do not delete or de-identify any Student Data from an active student user account associated with a School except at the direction of the School. The School is responsible for maintaining current student rosters and identifying Student Data which the School no longer needs for an educational purpose by removing students from the school's master roster or by submitting a deletion request.

Unless otherwise directed by a School or Parent, we will delete or de-identify personal information of student and child users after a period of inactivity, after the termination or cancellation of the license subscription, or after termination of our agreement with the School, in accordance with the terms of any applicable written agreement with the School, written requests from authorized School administrators, and our standard data retention schedule. Authorized School administrators may contact us to request additional information about our standard data retention schedule and available options for customizing DC Math and Martial Science Club, LLC's standard data retention schedule to meet individual School requirements.

We may not be able to immediately or completely delete all data in all instances, such as information retained in technical support records, customer service records, backups, and other similar business records. We will not be required to delete any information which has been de-identified or disassociated with personal identifiers such that the remaining information cannot reasonably be used to identify a particular individual.

8. How does DC Math and Martial Science Club, LLC protect your information?

Information Security. The security of your personal information is very important to us. We have implemented a variety of physical, administrative and technological safeguards designed to preserve the integrity and security of the personal information we collect and to protect against unauthorized access to data. These include internal reviews of our data collection, storage, and processing practices and security measures, as well as physical security measures to guard against unauthorized access to systems where we store personal data. We restrict access to personal information to DC Math and Martial Science Club, LLC employees, contractors, and agents who need to know that information in order to operate, develop, or improve our services. Our employees may be subject to disciplinary action, including termination, if they fail to meet privacy and confidentiality obligations. However, no security system is impenetrable—for that reason, we cannot guarantee the security of your personal information. If personal information under our control is compromised as a result of a breach of security, we will take reasonable steps to investigate the situation and take all steps required by applicable laws and regulations and our agreements with any affected Schools.

Maintaining the security of your personal information also requires your cooperation and involvement. For your protection, remember to sign out of all accounts before closing your browser. There is a sign out link available on most DC Math and Martial Science Club, LLC pages. After signing out, make sure to close all browser windows. In addition, do not use the "Remember" feature if you are signing in to your account from a computer that other persons may have access to. This is to ensure that others cannot access your personal information if you share a computer with someone else or are using a public computer.

Please keep your password secure. If you have forgotten your password, you may request a new one by contacting Home | DC Math & Martial Science Club. A new password will be sent to the e-mail address you specified during registration. For all other problems signing in to the DC Math and Martial Science Club, LLC Service, please contact our technical support team using the contact information at the end of this policy.

If you have any concerns about the security of your account or the security of the Service, we ask that you report your concern to us immediately at Home | DC Math & Martial Science Club.

Please note this section does not apply to Student Data that we process on behalf of our School customers. Because DC Math and Martial Science Club, LLC provides the Services to Schools as a "School Official," we collect, retain, use and disclose Student Data only for or on behalf of our School customers for the purpose of providing the Services specified in our agreement with the School and for no other commercial purpose. If you have any questions or would like to exercise your California rights, please contact your School directly.

To request to exercise your right to know and/or right to deletion, please submit a request by mail to the address below, with the subject line, "California Rights Request." We will need to verify your identity before processing your request, which may require us to request additional personal information from you or require you to log into your account, if you have one. In certain circumstances, we may decline or limit your request, particularly where we are unable to verify your identity or locate your information in our systems, or as permitted by law.

We do not "sell" personal information to third parties without consent, however, we do allow certain third party advertising networks and other third party businesses to collect your personal information directly from your browser or device through cookies and related technologies for advertising, attribution, analytics and research purposes. These third parties may use such personal information for their own purposes in accordance with their own privacy statements, which may include reselling this information to additional third parties. By visiting www.privacyrights.info, you can opt out from sales of this type of personal information by businesses that participate in the DAA's CCPA App-based Opt-Out Tool.

Please see the section called "Third-party tracking and online advertising" for more information about how third parties use cookies and related technologies to collect information automatically on our websites and other online services, and the choices you may have in relation to those activities.

Shine the Light. California "Shine the Light" law (Civil Code Section §1798.83) provides certain rights to California residents that have an established business relationship with us with regard to the disclosure of certain types of personal information to third parties for their direct marketing purposes. We do not share your personal information with third parties for their direct marketing purposes without consent.

Minors. We do not sell the personal information of consumers we know to be less than 16 years of age, unless we receive affirmative authorization (the "Right to Opt In") from either the minor who is between 13 and 16 years of age, or the parent or guardian of a minor less than 13 years of age.

• The processing is necessary to comply with a legal obligation, a court order or to exercise or defend legal claims;

The Student Privacy Pledge ("The Pledge"). DC Math and Martial Science Club, LLC adheres to the Student Privacy Pledge, an industry standard approach to privacy for K-12 service providers. The Pledge was created by the Future of Privacy Forum (FPF) and The Software & Information Industry Association (SIIA) and has been endorsed by the National School Boards Association (NSBA), the National Parent-Teacher Association (PTA), and the White House.

As part of our commitment to The Pledge, when we have access to Student Data through the provision of our Services to a School, the following core principles guide our decisions around data, security, and technology:

• DC Math and Martial Science Club, LLC does not collect, maintain, use or share Student Data beyond that needed for an authorized educational or school purpose, or as authorized by our agreement with a School.

• We will not make any material changes to our Privacy Policy or Terms of Service that relate to the collection or use of Student Data without first giving notice to the School and providing a choice before the Student Data is used in a materially different manner than was disclosed when the information was collected.

The Family Educational Rights and Privacy Act ("FERPA").

​​​​​​​​​​​Effective: May 12, 2026

​

DC Math and Martial Science Club, LLC does not permit children under the age of 13 ("Child") to create an account and does not knowingly collect personally identifying information from children under the age of 13 without the consent and at the direction of a parent.

DC Math and Martial Science Club, LLC permits Parents to set up child profiles associated with the Parent account so that children may access the Service under the Parent's supervision. We take special precautions to collect only as much information as is reasonably necessary for the child to use the Service and to ensure that Parents have access to and control of their child's use of the Service.

This Children's Privacy Policy applies to all users of child profiles associated with a Parent account, regardless of the age of the child.

By creating a child profile associated with a Parent account and permitting your child to use the DC Math and Martial Science Club, LLC Service, you expressly agree to the practices described in this Children's Privacy Policy and you consent to the collection, use, and disclosure of your child's personal information as described herein.

​

1. How to create a child profile associated with a Parent account.

A parent must purchase a package using a credit card on the Membership page, register for an account with DC Math and Martial Science Club, LLC, and agree to the terms of our Terms of Service, Privacy Policy and this Children's Privacy Policy. During the account creation process, the Parent may create individual profiles for each child(ren) authorized by the Parent to use the Service through the Parent's account.

2. What information does DC Math and Martial Science Club, LLC collect from or about a child and how does DC Math and Martial Science Club, LLC use this information?

Information you provide us. Through the Parent's account set-up, the Parent provides information about the child(ren) authorized by the Parent to use the Service through the Parent's account, including a profile name and selection of a profile avatar. We recommend that the Parent selects a profile name that does not include the real name or identifying characteristics of the child. The Parent may also create a "secret word," which functions similar to a password to access the child profile, though it cannot be used to sign in to the Service without the Parent first signing in to the Parent's account using the Parent's login credentials. DC Math and Martial Science Club, LLC does not request a birthdate or any additional personal information from the user of the child profile, though the child may change his/her profile avatar, secret word and profile name (of course, the Parent will see these changes through the Parent's account dashboard).

DC Math and Martial Science Club, LLC uses this information to provide the Service to the user of the child profile. DC Math and Martial Science, LLC uses the e-mail address provided by users of Parent accounts to communicate messages about the account, such as subscription notices and password resets, and the child user reports and awards.

Information collected from the Child's use of the Service. During the course of providing the Service, we collect information about the user of the child profile's use of the Service and information submitted to the Service, such as answers to questions, for the purpose of providing feedback to the user and for compiling reports and awards.

When your Child accesses the Service through the Parent's account, we automatically collect and store usage information as well as information about the device used by the Parent and Child to access the Service. For example, we collect an IP address, location (at the city level), browser type, language preferences, and other information about the device used to access the Service, such as the device type, model and manufacturer and a unique identifier which allows us to uniquely identify your browser, device, or account, as well as account usage information such as the day/time stamp, referring/exit pages and URLs, pages viewed, and similar information. This information is typically collected through a variety of tracking technologies, including cookies, web beacons, log files, and similar technology (collectively, "tracking technologies"), and we may use third party providers to collect this information on our behalf. This data collection is explained in greater detail in Section 1 of our Privacy Policy under the sub-heading "Information we receive when you use the Service."

We use this information to secure and improve the Service, to provide personalized content and information, to remember you when you return to the Service at a later time or using a different device, to improve the Service, to save you time, to provide better technical support, to track website usage and other similar purposes.

​

3. How we disclose information

DC Math and Martial Science Club, LLC may share or disclose a child's personal information as needed to provide our Service or with your consent or permission. For example, we share information with our trusted vendors, third party service providers and individuals to provide services for us on our behalf, which may include analytics providers and hosting services. We may also share personal information if we have a good faith belief that access, use, preservation, or disclosure of such information is reasonably necessary to (a) satisfy any applicable law, regulation, legal process, or enforceable governmental request; (b) enforce applicable Terms of Service, including investigation of potential violations thereof; (c) detect, prevent or otherwise address fraud, security or technical issues; (d) protect the rights, property, or personal safety of DC Math and Martial Science Club, LLC, its users, or the public; or (e) as required or permitted by law.

If DC Math and Martial Science Club, LLC becomes involved in a merger, acquisition, bankruptcy, change of control, or any form of sale of some or all of its assets, personal information may be transferred or disclosed in connection with the business transaction, subject to any applicable laws.

We may also share aggregate or de-identified information in a manner that cannot be reasonably used to identify an individual user.

4. Third party tracking and online advertising on the Service

DC Math and Martial Science Club, LLC does not display any targeted advertising on the Service.

We work with third-party online advertising networks which use tracking technologies (such as cookies, web beacons and similar technologies) to collect information about visitors to direct targeted advertising on other websites or services. You can learn more by referring to Section 4 of the DC Math and Martial Science Club, LLC's Privacy Policy called "Third party tracking and online advertising," and by visiting the Digital Advertising Alliance's resources at http://www.aboutads.info/choices and/or the Network Advertising Initiative's online resources, at http://www.networkadvertising.org.

We take certain steps designed to avoid these third-party tracking technologies from collecting information from users of Child profiles for targeted advertising purposes, by taking steps to disable such tracking technologies once a subscriber to our Service (e.g., the Parent) logs into our Service, maintaining the preferences for as long as the subscriber is signed in, and by remembering these preferences the next time you return to our Service using the same browser or device. Please note that we rely on cookies to identify whether you are a Subscriber and if you delete or block cookies you may also delete the DC Math and Martial Science Club, LLC cookie which allows us to recognize returning users and prevent subscribers from receiving targeted DC Math and Martial Science Club, LLC advertisements on other websites or services. These preferences are unique to the browser or device you used to sign in to the Service. Therefore, third-party tracking technologies may be present if you navigate to certain pages of our website using a new browser or device until you sign in to your account on that browser or device.

5. How to access and delete your child's personal information

The Parent may review the information collected from the user of the child profile at any time by signing in to the Parent account. The Parent may refuse to permit the further collection of the child user's information by no longer providing the child user access to the Service through the Parent's account.

DC Math and Martial Science Club, LLC will retain the personal information collected from and about the user of the child profile for as long as necessary to provide the Service and will de-identify or delete the personal information within three years of the termination of the Parent's subscription account or when we receive a deletion request. To request deletion of personal information of a user of a child profile at any time, please contact us at the address below.

7. Region-Specific Disclosures

We may choose or be required by law to provide different or additional disclosures relating to the processing of personal information about residents of certain countries, regions or states. Please refer to the Region-Specific Disclosures section of our Privacy Policy to learn more.

8. Contact us
