Data stored on the device

The game saves only on this device:

• High scores, stats, and daily-challenge best
• Settings (language, audio, haptics, accessibility, keybindings)
• Onboarding hint flags

Files live in the app sandbox (user://). STACKRA does not upload them.

Data we do not collect

STACKRA does not use accounts, analytics SDKs, advertising, crash reporters, or cloud saves. It does not read contacts, location, photos, or the clipboard except when you tap Share (then the result text is copied locally so you can paste it yourself).

Permissions

• Vibrate / haptics: optional feedback. Can be turned off in Settings.
• Internet: not required for play. If a store build requests network, it is for the engine or store, not for STACKRA accounts.

Children

The game is a general-audience puzzle. We do not collect personal data, including from children.

Sharing

We do not sell or share player data. There are no third-party ad or analytics partners in the current build.

Retention and deletion

Uninstalling the app deletes local saves. There is no server copy to erase.

Changes

If a future version adds online features (leaderboards, cloud save), this policy will be updated before those features ship.

Questions

STACKRA has no in-game inbox and does not ask for an email address. Use the store listing for this app if you need to reach the publisher. Do not send personal information through the game.
