KIDOKU | PRIVACY POLICY

KIDOKU Privacy Policy (effective 7 November 2026)
Operator: PINWORLD (핀월드)
Google Play developer: PINWORLD GAMES
Contact: contact.pinzero@gmail.com

KIDOKU stores Sudoku progress, completed levels, in-progress numbers, lives, shared hints and settings on the device. It does not create an app account. Android backup may copy app data according to the device's backup settings. Clearing app data or uninstalling normally removes local records; a backup may restore them. Time Attack tickets, active runs, elapsed time and personal Top 10 records are also stored locally.

The Play internal QA build can request Google official test ads. The Google Mobile Ads SDK may process device, network and ad interaction information. Requests are marked child-directed, under age of consent and non-personalized, with a G content rating. Public builds request production ads during eligible free Classic level transitions. Review requests use the Google Play In-App Review API. No analytics SDK or location, camera, microphone or contacts permission is included.

Google Play handles payments. KIDOKU receives the product ID, purchase state and purchase token through Play Billing to determine Premium access and acknowledge completed purchases; it does not receive card numbers. This version does not send purchase tokens to a KIDOKU-operated server. Google Play may process payment and device information under its own policy. The app refreshes ownership when it starts or resumes. If Play is temporarily unavailable, a recent successful check may remain active for up to 24 hours in the same app session.

Clearing app data or uninstalling normally deletes local records, although Android backup may restore them. For questions about data or deletion, contact PINWORLD at the email above. Please do not send children's personal information. Google Play purchase records and third-party service data are handled under those providers' policies.
