Games by Ian Corbin · Last updated October 16, 2026
This policy covers every game published by Ian Corbin on the App Store, including Proof ∎.
My games don't collect, store, or share any personal information. There are no accounts, no ads, and no tracking.
Your progress and settings (for example, puzzles solved, your streak, and your chosen ink colours) are saved only on your device. They're never sent to me or anyone else. Deleting the game deletes them.
If you've chosen to share analytics with app developers in your device settings, Apple may provide me with aggregated, anonymous statistics such as the number of downloads, sessions, and crashes. I can't see who you are from this information. You can turn this off at any time in Settings › Privacy & Security › Analytics & Improvements › Share With App Developers.
When you choose to share something (for example, your Today's Proof card), it goes only where you send it, using Apple's share sheet. I don't receive a copy.
My games are suitable for all ages and collect no information from anyone, including children.
If a game ever starts collecting any information, this policy will be updated before that happens, and the change will be noted on this page.
