LetPiano collects no personal data. There are no servers operated by us, no analytics, no tracking, no advertising, and no account or login — and the app runs fully offline. This App is fully compliant with Apple's "Made for Kids" guidelines and the Children's Online Privacy Protection Act (COPPA). We do not collect any personally identifiable information from users, including children under the age of 13.
What the app stores, and where
- Game progress (level, XP, daily streak, missions, best stars per song) is stored on your device only and never transmitted to any server.
- Settings (octave range, language, sound toggles, etc.) are stored on your device only.
- Family profiles (local profile names such as "Baby / Mom / Brother" and their separate progress) are stored on your device only, with no account, and are not accessible to us.
What we do NOT collect
- No name, email address, or any personal identifier
- No location data
- No voice or audio (the app's sound is synthesized on-device in real time — there is no recording and no microphone use)
- No usage analytics or crash reporting sent to us
- No advertising identifiers (IDFA); we do not use App Tracking Transparency (ATT)
- No third-party SDKs that collect data
Children's privacy (COPPA / GDPR-K)
LetPiano is designed for children to use under parental supervision. Because we collect no data at all, the app complies with COPPA (US) and GDPR-K (EU) by design. No information about child users is ever collected, stored outside the device, or shared.
No sensitive permissions requested
LetPiano does not request microphone, camera, photos, location, or contacts permissions. All sound is synthesized on-device from a built-in piano instrument — there is no recording and no microphone needed.
Third-party services
LetPiano uses no third-party analytics, advertising, or tracking services, and makes no network connections.
Third-party asset licensing
The app uses the "YDP Grand Piano" sound from the FreePats project (licensed under Creative Commons Attribution 3.0 / CC-BY 3.0), credited in the app under Settings → Credits. Reward animations use the open-source ConfettiSwiftUI (a pure UI animation library that collects no data). None of these assets collect any data.
Ad-Free Experience
To ensure a safe environment for children, this App is 100% ad-free. We do not display any third-party advertisements or use any ad-tracking mechanisms.
Outbound Links & Parental Gate
Any external links (such as a support email, App Store page, or any purchase entry point added in the future) are secured behind a Parental Gate to ensure children cannot access the internet or leave the App without adult supervision.
Purchases
The initial release is completely free with no in-app purchases. If paid features are added later, the purchase entry will always sit behind a parental gate and be handled by Apple's payment system; this policy will be updated accordingly.
Data deletion
All app data is stored locally on your device. To delete it, uninstall the app, or delete individual family profiles within the app settings.
Changes to this policy
If this policy changes, we will update the effective date above. Significant changes will be noted in the App Store release notes.
