DK Sudoku Support
Questions, problems or ideas? Email support@dk-squared-studio.com. Write in whichever language you prefer: we reply in English or German, and translate messages in other languages. In the App, Settings → Suggest an improvement starts the email for you and adds your App version.
Manage or cancel your subscription
The DK Sudoku subscription renews automatically every 3 months until you cancel it. Cancelling stops future charges, and you keep full access until the end of the period you've paid for. Uninstalling the App does not cancel it.
- Android: open Google Play, tap your profile picture → Payments & subscriptions → Subscriptions → DK Sudoku → Cancel subscription.
- iOS: Settings → your name → Subscriptions → DK Sudoku → Cancel Subscription.
If you switch to the one-time purchase, remember to cancel the subscription as well, or it will keep renewing.
Restore a purchase on a new device
Sign in to the same Google Play (or Apple) account you bought with, open DK Sudoku and tap Restore Purchase on the unlock screen. An active subscription is recognised automatically when the App starts.
Refunds
Payments are handled by the store, so refunds follow its policy. Request one from Google Play or Apple. For Google Play purchases you can also email us with your order number (it starts with GPA. and is in your Google Play receipt), and we'll look at your case.
Achievements and leaderboards
On Android these use Google Play Games. If you have a Play Games profile, the App connects when it starts. Wins you played offline or before connecting are sent the next time it connects. If nothing appears, check that you're signed in to Play Games, then restart the App.
Your progress and your data
Your games, statistics and settings are stored only on your device. There is no DK Sudoku account, and we can't see or restore your progress. A device backup you've set up yourself may restore it on a new phone.
- Delete your App data: clear the App's storage in your device settings, or uninstall it.
- Delete your Play Games data: use your Play Games profile.
- Anything else: email us and we'll delete our correspondence with you.
