Effective July 2026
Lapilli Stones collects no data. None. The app has no analytics, no advertising, no tracking, and no account system of its own. Your games are stored on your device.
Games against the computer or a friend on the same device work entirely offline. Game state and settings are saved locally on your device. Finished games are recorded to your game archive, which syncs between your own devices through your iCloud account when you are signed in, and stays on the device when you are not.
The app keeps your lifetime win/loss records. If you use more than one device, those records and your game archive sync between your own devices through your iCloud account, using Apple's iCloud storage. Apple carries that data under Apple's privacy policy; we operate no servers and cannot see it.
Optional online matches use Apple's Game Center. When you play online, Apple's Game Center service handles your player identity, match invitations, and the transfer of moves between players. This is governed by Apple's privacy policy, not ours — we operate no servers and receive no data. The information inside a match is the game itself: the moves played, the rules in force, whose turn it is, and the result — nothing about you beyond your Game Center identity.
We do not collect, store, sell, or share any personal information. We embed no third-party SDKs. The app's only network activity is through Apple's services: Game Center carries your online matches, and iCloud carries your own records and game archive between your own devices when you choose to play online.
The app is rated 4+ and collects no data from anyone, children included.
