Tingyu (听雨) is an app that plays the sound of rain on your device.

What we collect

Nothing. Tingyu has no account, ads, analytics or third-party SDKs, connects to no server of its own, and sends no information off your device.

What stays on your device

Tingyu saves a few settings on your device so it opens the way you left it:

• Appearance (automatic / day / night)
• Scene (Rain Curtain / Countryside / Moon Pond / Storm Town / Harbor City)
• The last rain intensity you chose
• Motion effects (full / reduced)
• Whether all scenes are unlocked
• Whether you have already used “tap to start” and “pull up for a timer” (so the hints stop showing)
• Whether to play alongside other apps' audio or on its own
• Whether you have seen the introduction shown on first launch
• How many times the Harbor City “what you can tap” hint has been shown (at most twice)
• The install date, how many full listening sessions you've had, and the app version when it last asked for a rating (used to decide when to ask you to rate it on the App Store, at most once per version)

Tingyu also caches the rendered scene images on the device so they open faster next time; the system can clear them when space is low.

These settings and the cache are deleted with the app. Neither we nor any third party can read them.

Purchases

“Unlock All Scenes” is bought through Apple's App Store. Payment, your Apple Account and your purchase history are handled by Apple; we never see them. Tingyu only asks the App Store on your device whether you have bought it, to unlock the scenes. For how Apple handles this information, see the Apple Privacy Policy.

Permissions

Tingyu does not ask for location, camera, microphone, contacts, photos or notifications. Background audio is used only to keep the rain playing after you lock the screen.

Children

Tingyu collects no information from anyone, including children.
