StackDrop does not collect, store, or share any personal information.
Your high scores and your sound/haptics preferences are saved only on your device, using standard iOS app storage. They never leave your device unless you choose to share a score card.
If you sign in to Apple's Game Center, your scores are submitted to Apple's leaderboards under your Game Center profile. This is handled entirely by Apple and governed by Apple's Privacy Policy. Game Center is optional; the game works fully without it.
The Share button creates an image of your score on your device and hands it to the iOS share sheet. Nothing is sent anywhere by StackDrop itself.
StackDrop contains no advertising, no analytics, no third-party SDKs, and does not require an account.
StackDrop is rated 4+ and does not knowingly collect any information from anyone, including children.
