Privacy
without a gambit.
Worst Chess Move does not collect, transmit, share, or sell personal data.
Data stored on your device
The app stores your selected game settings and, when applicable, the state of one unfinished chess game. This information remains in the app's private storage on your device and is used only to restore your preferences and let you continue that game.
Network use and third parties
Gameplay and the Sage and Jester models' chess analysis run entirely on your device. The app does not require an account or internet connection and contains no advertising, analytics, tracking, social, or cloud-sync service. No third party receives your game state or personal data from the app.
Device permissions
The app does not request access to your microphone, camera, photos, contacts, location, or other personal content. It can use the device's standard audio output and haptic feedback for optional game effects.
Retention and deletion
Locally stored settings and game state remain until you replace them, clear the app's storage, or uninstall the app. Clearing the app's storage or uninstalling the app deletes that local data.
Children
The app does not knowingly collect personal information from anyone, including children.
Changes
If the app's data practices change, this policy and the disclosures on its store listings will be updated before the change is released.
Contact
Privacy questions can be sent to the developer support address published on the app's Apple App Store and Google Play listings.
