Privacy Policy

Last updated: August 2026

NumJam respects your privacy and aims to process personal information transparently and securely.

This Privacy Policy explains what information NumJam collects, why it is used, how it may be shared, how long it may be retained, and the rights available to users.

1. Who is responsible for your data?

The person or entity operating NumJam is responsible for the processing of personal data through the service.

Data controller: [YOUR LEGAL NAME OR BUSINESS NAME]

Contact email: [YOUR PRIVACY EMAIL]

Country: France

If NumJam is operated as an individual business, the appropriate legal identity and required business information should be provided here.

2. Information NumJam collects

Depending on how you use NumJam, the following categories of information may be processed.

Account information

This may include your first name, last name, username, email address, encrypted or hashed password information, account creation date, verification status, and login-related information.

Gameplay information

This may include games played, difficulty level, whether negative numbers were enabled, scores, answers, correct and incorrect answers, response times, game duration, game completion status, and high scores.

Social information

This may include friend requests, friendships, friends' scores where available, and information used to provide online or offline status functionality.

Subscription information

This may include your subscription plan, subscription status, activation and expiration information, Stripe customer or subscription identifiers, and other information necessary to determine your access to paid functionality.

Payment-card details are processed by Stripe and are not intended to be stored directly by NumJam.

Technical information

NumJam may process information reasonably necessary for security, authentication, operation, diagnostics, and protection of the service, such as session information, browser or device information, logs, and IP-related information where applicable.

3. Why your information is used

Personal information may be processed to:

  • Create and manage your account
  • Authenticate users
  • Verify email addresses
  • Operate NumJam games
  • Save scores and statistics
  • Provide score history
  • Operate friendship and social functionality
  • Manage Jam Plan access
  • Process and administer subscriptions
  • Maintain security
  • Prevent abuse
  • Diagnose technical problems
  • Improve the service
  • Comply with legal obligations

Under applicable data-protection law, these activities may rely on different legal bases, including performance of a contract, compliance with legal obligations, legitimate interests in operating and securing NumJam, and consent where consent is specifically required.

4. Payments

Payments for the Jam Plan are processed using Stripe.

When purchasing a subscription, payment and billing information may therefore be provided directly to Stripe and processed according to Stripe's own privacy practices.

NumJam may receive information from Stripe necessary to administer your subscription, such as a customer identifier, subscription identifier, payment or subscription status, billing period, and cancellation status.

NumJam does not need to receive or store your complete card number in order to provide the subscription.

5. Email communications

NumJam may use your email address for communications necessary to operate your account, including email verification, password resets, security-related messages, subscription-related information, and important service communications.

If promotional or marketing emails are introduced in the future, they will be handled separately in accordance with applicable consent and electronic-communications requirements.

6. Cookies and sessions

NumJam may use cookies or similar browser technologies that are necessary to keep users logged in, maintain sessions, protect forms and requests, preserve security, and provide essential website functionality.

If NumJam later introduces non-essential analytics, advertising, tracking, or similar technologies requiring consent, appropriate information and consent mechanisms should be provided before those technologies are used where required by law.

7. Who receives your information?

Personal information is not sold to advertisers.

Information may be processed by service providers where necessary to operate NumJam. These may include providers for payment processing, hosting and infrastructure, email delivery, database services, security, and other technical services.

These providers should receive only the information necessary to perform their respective services and process it subject to applicable contractual and legal requirements.

Information may also be disclosed where required by law or where reasonably necessary to establish, exercise, or defend legal rights.

8. International data transfers

Some service providers used by NumJam may process information outside France or the European Economic Area.

Where personal data is transferred internationally, appropriate safeguards required under applicable data-protection law should be used where necessary.

9. Data retention

Personal information is retained only for as long as reasonably necessary for the purposes for which it was collected and for applicable legal, accounting, security, or dispute-resolution requirements.

Account and gameplay information may generally be retained while your account remains active.

Certain information may need to be retained after account deletion where required by law or where necessary for legitimate purposes such as fraud prevention, security, accounting, or resolving disputes.

Retention periods may vary depending on the type of information involved.

10. Security

NumJam uses reasonable technical and organizational measures intended to protect personal information from unauthorized access, alteration, disclosure, or destruction.

Passwords are intended to be stored using secure password-hashing techniques rather than as readable passwords.

However, no online system can guarantee absolute security.

11. Your rights

Depending on applicable law, particularly the EU General Data Protection Regulation (GDPR), you may have rights concerning your personal data.

These can include the right to access your personal data, correct inaccurate information, request deletion, restrict certain processing, object to certain processing, receive certain data in a portable format, and withdraw consent where processing is based on consent.

You may exercise applicable rights by contacting:

[YOUR PRIVACY EMAIL]

You may be asked to provide information reasonably necessary to verify your identity before a request is completed.

You also have the right to lodge a complaint with the competent data-protection authority. In France, this is the Commission nationale de l'informatique et des libertés (CNIL).

12. Account deletion

Users may request deletion of their NumJam account and associated personal information by contacting NumJam at the address provided in this Privacy Policy or through an account-deletion feature where available.

Some information may be retained where required by law or where another valid legal basis permits or requires its retention.

13. Children's privacy

NumJam is not specifically designed as a service for young children.

If NumJam is made available to minors, additional requirements concerning age, parental authorization, data protection, and consumer protection may apply depending on the user's age and jurisdiction.

NumJam may introduce additional age-related measures where necessary.

14. Changes to this Privacy Policy

This Privacy Policy may be updated as NumJam develops, introduces new functionality, changes service providers, or needs to comply with new legal requirements.

The latest version will remain available through NumJam with its last-updated date.
