Privacy Policy — Mind Map Duel

Effective: November 4, 2026 · App Architects Abroad

Mind Map Duel is designed with privacy as a default. Almost all game processing happens entirely on your device. No words you type are sent to a server, and the core game works fully offline without an account. For players confirmed as 13 or older, online leaderboard participation uses an anonymous guest account.

For help with public app version 2.0.2, including privacy and deletion requests, see Mind Map Duel Support and the Data Retention & Deletion section below.

What We Collect

The table below summarizes the game data and service data described in this policy.

Gameplay and Account Information

You do not need to provide your real name, email address, phone number or location to play. Offline play does not require an account. Online leaderboard participation uses an anonymous guest account without an email or password; uploaded display names and scores are public. If you contact support by email, we receive the address and information you choose to send.

The words you type during gameplay are validated entirely on-device using an offline model. They are never transmitted to any server.

Leaderboard records include a random player ID associated with the anonymous guest account. Public usernames, player IDs and scores do not prove account ownership. Users who indicate they are under 13 do not create our guest accounts, submit scores or send product analytics.

Third-Party Services

We use the following third-party services, each with their own privacy policies:

• Google AdMob — Serves non-personalized banner ads on the free tier. May collect advertising or device identifiers; the app does not access the iOS advertising identifier (IDFA).
• RevenueCat — Manages purchase history and ad-free entitlements using a separate anonymous customer identity.
• Supabase — Provides anonymous guest accounts and stores optional public leaderboard records, including player IDs, display names and scores.
• PostHog — Product analytics to measure retention and game engagement, including usage events, crash logs and device/guest identifiers. Analytics can be associated with the guest ID and username and are enabled only for players confirmed as 13 or older.

Advertising

The free version of Mind Map Duel displays non-personalized banner ads provided by Google AdMob. AdMob may collect advertising or device identifiers for contextual ad serving, frequency capping and fraud prevention. The app does not access the iOS advertising identifier (IDFA) and does not use ads for cross-app targeting. For users who indicate they are under 13, ads are served using Google AdMob’s child-directed treatment, which restricts ad content and limits the use of advertising identifiers.

The one-time ad-free upgrade removes banner ads. When the ad-free entitlement is active, ad banners are not loaded.

Children’s Privacy

Mind Map Duel has a mixed audience that includes players under 13 and uses a neutral age screen to apply the protections described below.

On first launch, the app asks for your age range. If you indicate you are under 13, the app does not create our guest accounts, submit scores or send product analytics. The full game remains playable, and the leaderboard remains viewable, but participation in it is disabled. Advertising for these users is configured for child-directed treatment in accordance with Google AdMob’s COPPA settings.

If you believe a child’s information has been submitted contrary to these protections, please contact us.

Data Retention & Deletion

Guest accounts and retention. For players confirmed as 13 or older, online leaderboard features use an anonymous guest account. Uploaded records include a random player ID, display name, daily score, word count and prompt date. Leaderboard records are public. We keep guest accounts and uploaded scores until deleted; there is no automatic 90-day deletion.

Data and deletion requests. Contact [email protected] for help with a privacy or deletion request. The current app does not have an in-app account deletion control. Guest accounts have no email or password, and public names, player IDs and scores do not prove ownership. We cannot authorize deletion from those details alone. If the guest login is lost, we may be unable to verify that the account belongs to you. Do not send login tokens or other credentials by email.

Removing the app or resetting local progress does not delete uploaded scores. Purchase records are handled separately by the purchase providers. Players under 13 do not create our guest accounts, submit scores or send product analytics; they can view public standings and receive ads with child-directed treatment.

See Mind Map Duel Support for current-app help.

Your Rights

Depending on your location, you may have rights under applicable privacy law (including GDPR, CCPA, and similar regulations) to access, correct, or delete data we hold about you. Removing the app or resetting local progress does not delete uploaded scores. Contact us for help with your request; the ownership-verification limits described above apply.

Purchase records are handled separately by the purchase providers. Contact us for help with purchase-related data questions; the providers’ privacy policies are linked above.

For leaderboard data deletion or any other privacy requests, contact us at the address below.

Changes to This Policy

We may update this policy as the app evolves. Material changes will be noted with a revised effective date at the top of this page. Continued use of the app after changes constitutes acceptance of the updated policy.
