Stillstone — Privacy Policy & Support

Last updated: 3 November 2026. Applies to Stillstone 1.0.1.

Stillstone is a single-player puzzle game. No account or sign-in is required. The developer does not collect gameplay, Health records, advertising identifiers or device identifiers. The app has no advertising, tracking or third-party analytics SDK.

Local game data and sharing

Progress, scores, collected stones and saved positions are saved locally. Stillstone has no developer-operated account or automatic game-progress sync. Your device’s own backup and storage settings may apply to local app data.

You can export a progress backup or choose to share an image or playable position. Only the destination you select receives that export; its own privacy and storage policies apply. Keep a backup before changing devices. Deleting the app removes its local progress; copies you exported or shared must be deleted separately from their destinations.

Optional Apple Health

Mindful sessions are free, off by default and independent of purchases. Stillstone requests permission to write Mindful Minutes only; it does not read your existing Health records.

After permission is granted, you must choose Start mindful session. You then choose End session & save to Health. Ordinary play and puzzle completion do not automatically create Health records. Only foreground session intervals count; menus, alerts, background time and audio interruptions are excluded. At least one minute is required to save.

This records your self-selected activity, not a medical measurement or a claim of health benefit. Stillstone does not send Health records to the developer or use them for advertising or marketing. Apple’s own Health storage and synchronization depend on your device settings.

Unsaved session intervals remain in memory and disappear when the app quits. A failed write may be retried or discarded during the current app session. Turning the option off stops recording and discards unsaved intervals. Existing records remain in Apple Health; you can delete them and revoke Stillstone’s permission there. Declining permission never restricts game content.

Purchases

Apple handles purchases and restoration through StoreKit. Stillstone does not receive card or billing credentials. The optional full-game purchase is a non-consumable, one-time purchase; it is not a subscription. Apple verifies purchase entitlement.

Support and privacy contact

Email: madebyxiaoshan@gmail.com

For support, include your device model, iOS/iPadOS version and the app version shown in Settings > About Stillstone. Do not send Health records, card details or account passwords.

If you voluntarily email support, your email address and the information you provide are used to answer your request. You can request deletion of support correspondence by contacting the same address, subject to any applicable retention obligations. The game itself does not ask you to provide an email address.

Restore a purchase

Open Settings > Full game access > Restore Purchases, using the Apple Account that made the purchase. Purchase restoration does not restore game progress. Progress backups are separate.

Privacy or deletion requests

For local progress, delete the app. For exported/shared files, delete the copies from their destinations. For saved Mindful Minutes, use Apple Health. For correspondence held by support, email the address above.

Changes to this policy

This policy will be updated before changes to the app’s data handling are released.
