Frequently Asked Questions

How do I restore my purchase?

Go to Settings (gear icon) and tap "Restore Purchase". This will restore your premium unlock on any device signed in with the same Apple ID.

Does the app work offline?

Yes. Inkgrid Sudoku is fully offline. Daily puzzles, statistics, and all features work without an internet connection.

How does iCloud sync work?

If iCloud is enabled on your device, your puzzle progress and statistics sync automatically across all your Apple devices. We never see or access this data — it stays within your iCloud account.

What does Premium include?

Premium is a one-time purchase that unlocks: Endless Challenge mode, all difficulty levels (Medium, Hard, Master), solution replay, enter-your-own puzzles, and iCloud sync.

What's free?

Daily puzzles, Easy difficulty in Endless mode, full note-taking tools, statistics, and the widget are all free forever.
