What to include
Describe the platform (iPhone, iPad, Android or web), app or browser version, language, page or screen, expected result, actual result and reproduction steps. Include a safe screenshot if useful.
Progress and local data
Progress is primarily local and is not automatically synced. Consider the risk of loss before clearing data or reinstalling. On the website, use browser site-data settings; in the app, use device data controls. There is no separate IRBIS Sudoku account to delete.
IRBIS+ and Restore Purchases
On iOS, first verify the Apple ID and internet connection, then use Restore Purchases. Manage the subscription in Apple Subscriptions; removing the app does not cancel it. On Android, manage or restore an IRBIS+ purchase in Google Play subscription settings; removing the app does not cancel the subscription there either.
Refunds
The operator does not process payment cards and cannot directly reverse a store transaction. For an iOS purchase, use Apple Report a Problem; for an Android purchase, use Google Play support and refund tools. Mandatory consumer rights remain available.
Privacy requests
For access, correction, deletion or another right concerning data actually held by the operator, contact support@irbissudoku.com. Local progress cannot be recovered from a server. Proportionate verification may be required.
Do not send secrets
Do not send an Apple or Google password, full card number, CVV, verification code or private information that is unnecessary to resolve the issue.
