Privacy Policy
Effective: October 18, 2026 · Applies to: the Sangsang Piano web app (sangsang-piano.pages.dev) and Android app (Google Play)
1. Data we collect
Sangsang Piano does not collect any personal data. There is no sign-up or login, and no collection of names, email addresses, phone numbers, location, contacts, or device identifiers.
2. Cookies, ads, and tracking
We use no cookies, no advertising, and no analytics or tracking tools (no analytics or ad SDKs).
3. What stays on your device
- Offline cache: the app's screen files and the audio of tracks you have played are stored in your device's browser storage so you can listen again without a connection.
- Settings: values such as volume, rain sound, playback mode, and your language choice (Korean or English) are stored in your device's local storage.
This data never leaves your device and we cannot see it. You can remove it at any time by clearing the app's data (or the site data in your browser) or by uninstalling the app.
4. Server logs
Audio and app files are served by Cloudflare Pages. The hosting provider may briefly process standard connection data (such as IP addresses) for security and operation; we do not collect, view, or use it.
5. Sharing
Because we collect no personal data, we share or sell none. Tapping the YouTube link takes you to YouTube, where YouTube's (Google's) privacy policy applies.
6. Children
The app is suitable for everyone and collects no personal data from any user, including children.
7. Changes and contact
If this policy changes, we will update this page with a new effective date. Contact: dkakrptehsrk@gmail.com
