Privacy Policy
Last updated: 15 September 2026
Summary
Mindfield is designed to collect as little as possible. Your scores, streaks, settings, and progress live on your device — we do not run any servers, and nothing about how you play leaves your phone. We never ask for your name or email. To measure our ads, an anonymous ID and whether you started a trial or subscribed may be shared with Meta — and, only if you allow tracking when iOS asks, your device's advertising ID (details below).
What stays on your device
- Game scores, personal bests, and accuracy history
- Streaks, sessions, and workout history
- Onboarding selections and notification preferences
- Mindfield Index value and tier progression
All of this is stored in your phone's local app storage and never transmitted off the device. Uninstalling Mindfield deletes it permanently.
What our payment provider sees
Mindfield uses Apple's App Store for all subscription purchases. Payment information is handled entirely by Apple — we never see your card details. To deliver and restore your subscription across devices, purchase receipts are processed by RevenueCat (privacy policy), which receives an anonymous ID it creates, your purchase history, and the anonymous Meta ID described below. If you allow tracking, it also receives your device's advertising ID (IDFA) and vendor ID (IDFV). RevenueCat may forward trial and subscription events — with the price, currency, that anonymous Meta ID and, if you allowed tracking, the advertising ID — to Meta so we can see which ads work.
Ads and measurement
There are no ads in Mindfield, and no analytics recording how you play. There is no Mixpanel, no Google Analytics, no Sentry.
We advertise Mindfield on Facebook and Instagram. To see which ads lead to trials and subscriptions, the app includes Meta's SDK (privacy policy). Its automatic event logging is turned off. It creates an anonymous ID, which the app passes to RevenueCat, and it contacts Meta when the app starts to load its settings. Meta never receives your name, email, or game data.
Tracking permission
The first time you see the subscription screen, iOS asks whether Mindfield may track you across other companies' apps and websites. If you allow it, the app reads your device's advertising ID (IDFA) and shares it with RevenueCat and Meta so a trial or subscription can be matched to the ad that led you to Mindfield. If you don't allow it, the advertising ID is never read. Mindfield works exactly the same either way, and you can change your choice at any time in Settings → Privacy & Security → Tracking.
Notifications
If you grant permission, Mindfield schedules a single local daily reminder. Notifications are generated and delivered on your device — they do not pass through our servers because we do not run any.
Children's privacy
Mindfield does not knowingly collect information from children under 13. The app requires no account creation and stores no personally identifying information.
Your rights and choices
- Delete your game data: Profile → Reset All Data inside the app, or simply uninstall. This does not remove the anonymous subscription records held by RevenueCat or Meta.
- Cancel subscription: iPhone Settings → your Apple ID → Subscriptions → Mindfield.
- Restore purchases: available on the paywall screen.
Changes to this policy
If we update this policy we will revise the date above. Material changes will be surfaced in the app the next time you open it.
