81 Numbers does not use accounts and never stores your real name or email. Progress and settings live on your device. If you play a world-record level, a random installation identifier and your best result are stored for the leaderboard, together with the optional display name you chose for it. This page explains how to delete both local and online data.
1. Delete on-device data
- iOS / iPadOS: touch and hold the 81 Numbers icon → Remove App → Delete App. This erases all locally stored game data.
- Android: Settings → Apps → 81 Numbers → Storage → Clear storage to wipe game data, or uninstall the app to remove it entirely.
2. Delete leaderboard data
Open 81 Numbers → Settings → Delete online scores and confirm. The App authenticates the request with this installation and permanently removes all of its leaderboard records. Local progress is not changed. Deleting the App alone cannot send this server request, so use this control before uninstalling.
Your display name stays reserved with your installation identifier after this step, so that nobody else can claim it while you are still playing. To have the nickname itself erased, send the deletion request in section 5 below.
3. Advertising privacy
81 Numbers shows ads via Google AdMob, which receives your advertising identifier. Depending on your region and your choices these ads may be personalised. You can change your mind at any time:
- In the App: Settings → Privacy options, where the consent message is shown in regions that require it.
- iOS: Settings → Privacy & Security → Apple Advertising, or Settings → Privacy & Security → Tracking to withdraw the tracking permission.
- Android: Settings → Google → Ads → Delete advertising ID.
4. Purchase records
In-app purchases are recorded by the Apple App Store or Google Play and by our purchase provider (RevenueCat) using an anonymous identifier. These records are kept as required for billing, tax, and fraud-prevention purposes and are managed through your store account. You can review your purchases in your Apple or Google account settings.
5. Request a manual deletion
If you would like us to delete any information associated with your device or purchases held by us or our providers, email us at support@minoom.com with the subject “Data deletion request”. Please include:
- Your device platform (iOS or Android);
- Your 81 Numbers installation identifier, if support asks you to copy it before deletion;
- Your leaderboard display name, if you chose one;
- Your purchase receipt or order ID, if you made a purchase.
We will process verified requests within 30 days. Some records may be retained where required by law.
