Privacy Policy
Skulldoku · Last updated October 24, 2026
The short version
Skulldoku doesn't collect, store or share any personal information. There are no accounts, no ads, no analytics and no tracking.
What stays on your device
Your runs, stats, streaks, records, the book of tricks, the skull's looks and your settings are saved only on your device, and shared with Skulldoku's home-screen widgets. The skull's memory of your habits lives there too. None of it is sent to me or anyone else. Deleting the app deletes it.
Game Center
If you're signed in to Game Center, Skulldoku sends your winning scores to its leaderboards. Game Center is Apple's service, run under your own Apple Account and covered by Apple's privacy policy. I can't see who you are from it.
Apple's analytics
If you've chosen to share analytics with app developers in your device settings, Apple may give me aggregated, anonymous statistics such as downloads, sessions and crashes. You can turn this off in Settings › Privacy & Security › Analytics & Improvements › Share With App Developers.
Sharing
When you share a Daily Skull card or a challenge code, it goes only where you send it, using Apple's share sheet. I don't receive a copy.
Children
Skulldoku is suitable for all ages and collects no information from anyone, children included.
Changes
If Skulldoku ever starts collecting any information, this policy will be updated before that happens, and the change will be noted here.
