Kinemath ("the app") is made by Yunpeng Chen (chirpet.com). In short: the app collects nothing.

Data we collect

None. Kinemath has no account, no server, no analytics, no advertising and no tracking SDKs. The app makes no network requests of its own.

Your settings, favorites and which formulas you've finished are stored only on your device and are deleted with the app.

Purchases and subscriptions are processed by Apple. We don't receive your name, email or payment details.

The app doesn't collect data from anyone, including children.
