Privacy policy

Effective 8 November 2026

Loopstone is an offline strategy game. It does not create user accounts, display advertising, track users or transmit personal information to the developer.

Purchases

Loopstone has no in-app purchases. Versions before 1.1.0 offered an optional Full Game purchase processed by Apple; from 1.1.0 the app no longer checks purchases at all. The developer never received payment details or operated a purchase server.

Data collection

Loopstone does not collect analytics, diagnostics, identifiers, location, contacts, photos, gameplay data or advertising information. It contains no third-party SDKs.

Local game data

Preferences, the current saved match and local play statistics are stored only on your device using Apple's local storage APIs. Statistics can be reset inside the app. Deleting the app removes its local data unless iOS later restores that data from a device backup.

Device permissions

Loopstone does not request access to location, contacts, photos, camera, microphone, Bluetooth, advertising identifiers or tracking.

Children

Because Loopstone does not collect personal information, it does not knowingly collect personal information from children or other players.

Changes

If a future version adds an online service or changes how data is handled, this policy and the App Store privacy disclosure will be updated before that version is released.
