Your game progress
Your puzzles, notes, settings and achievements are saved on your device. The app does not have an account or cloud progress sync.
Clearing the app's storage or uninstalling it removes local progress. Android system backup is disabled.
Restore Remove ads
For eligible adult users, Remove ads is a one-time purchase. Use Restore purchases in Settings with the Google Play account used for the purchase and an internet connection.
If you need help, include the Google Play order number or a redacted receipt. Never send passwords or full payment-card details.
Age and privacy choices
The game is intended for ages 13+. Choose your age group in Settings. Ads and purchases stay disabled for under-18 and unspecified users.
Choosing 18+ allows purchase services to start even before a purchase. Advertising services additionally follow the applicable consent choices. Eligible adults can revisit available choices through Privacy choices in Settings.
Report a problem
Tell us what happened, which screen or puzzle mode you were using, your Android version and app version. A screenshot can help if you are comfortable sharing it.
Please remove personal or payment information from anything you send.
Find a support ID
In Settings → Support & data requests, View support ID can show an existing anonymous purchase-service ID when those services are already available for your age choice. A purchase is not required.
Viewing or copying it does not start services or send the ID. It helps locate a record; it is not proof of identity. If it is unavailable, contact support with the information you still have. Do not change your age choice solely to make a request.
Privacy & data requests
Email support@asiansparrow.com with “Sparrow Sudoku privacy request” and what you would like us to review. Include a support ID or a redacted purchase reference if available.
Without a retained ID or purchase reference, a previous anonymous installation may not be identifiable. Clearing local data does not delete provider records or refund a purchase. See retention and deletion details, including restoration and records that may need to be retained.
