The short version
Mind Gym has no accounts, no analytics, no advertising and no tracking. It works without an internet connection, and your progress and flashcards never leave your device. We run no servers and we never receive your data. Game Center leaderboards are the one exception. They are on unless you switch them off, and if you are signed in to Game Center, your chimp test best, best Daily score and longest Daily streak are posted to Apple's Game Center under your Game Center name. Apple runs that service; we receive nothing. You can switch it off in Settings.
Who we are
Mind Gym is developed by Yash Khetan ("we", "us"). Contact: support@dpseven.com.
Data stored on your device
Mind Gym saves the following locally, and only locally:
- Game results, levels, skill ratings, streaks, XP, trophies, Academy progress, your Daily results, your chimp test best and settings, in the app's storage on your device (Application Support files and UserDefaults).
- Your Memory Lab decks, cards and review schedule.
- Your display name, if you enter one.
- Your daily reminder choice and time.
We never see this data. Apart from the three Game Center scores described under Network access, the app does not upload it or sync it anywhere (your device may include it in your own iCloud, Time Machine or computer backups). You can erase it with Settings › Reset all progress, which clears your game history, XP, trophies, Daily results, chimp test best, Academy lessons and Memory Lab review progress. Your decks, display name and settings are kept; delete decks or single cards in the Memory Lab, and clear your name in Settings. Scores already posted to Game Center stay there. On iPhone and iPad, deleting the app removes everything it saved. On a Mac, moving the app to the Trash does not delete its saved data.
What we do not collect
- No account, email address or phone number.
- No analytics, crash reporting, advertising or tracking SDKs, and no third-party code that contacts anyone.
- No advertising identifier, device identifier or location.
- No access to your contacts, camera, microphone or health data, and the app never reads your photo library. (If you save a share-card image, iOS and macOS grant add-only access to Photos.)
Network access
Every game, lesson, flashcard deck and post-game tip is built into the app and works without an internet connection. The only data the app sends is for Game Center leaderboards, which are on by default and can be switched off. With leaderboards on and Game Center signed in, three numbers go to Apple automatically: your chimp test best, your best Daily score and your longest Daily streak. They appear on the leaderboards under your Game Center name, where other players can see them. Nothing else you do in the app is sent anywhere, and nothing is sent to us. Switch leaderboards off in Settings, or sign out of Game Center in your device settings, and no scores are sent. Scores already posted stay on the leaderboards.
On devices with Apple Intelligence, the Coach (tips, the Coach chat, progress reports and Memory Lab help) uses Apple's on-device model. What it reads, such as your training stats and display name, is processed on your device and is not sent anywhere. You can switch it off in Settings › Coach. On other devices the Coach does not appear.
Apart from that, things go online only when you choose: the Privacy Policy and Support links in the app open this website in your browser, the share sheet sends a result card or text only where you choose to send it, and Apple's own App Store rating prompt may appear, which the app is not told the answer to. Reporting an AI tip opens an email to us in your email app, with the tip quoted; nothing is sent unless you send that email.
If a future version adds a feature that sends data off your device, we will update this policy before that version is released, describe exactly what is sent and to whom, and ask for your consent in the app first.
Backups
Export backup writes a JSON file to a location you choose. Import backup reads a file you choose. The app does not transmit the file; where you store or send it is up to you.
Notifications
Daily reminders are optional. If you switch them on, the app asks for permission and schedules a local notification on your device at the time you choose. Notifications are local only; no push notification service or server is involved.
Children
Mind Gym does not collect personal information from anyone, including children. Everything stays on the device, except the three Game Center scores described above, which Apple shows under the player's Game Center name.
Your rights
Because your data stays on your device, you already control it: you can view, change and delete it in the app. Under laws such as the UK and EU GDPR and the CCPA you may ask what we hold about you; the answer is nothing. Leaderboard scores are held by Apple's Game Center, not by us. Questions: support@dpseven.com.
Health disclaimer
Mind Gym is a training and learning tool. It is not a medical device and does not diagnose, treat or prevent any condition.
Changes to this policy
If this policy changes, we will update the date at the top and, for material changes, mention it in the app's release notes.
