DevBath ("the app") is a film development timer developed by Tong Zhang. It is a paid app with no ads.
We collect no data. The app requires no account, contains no analytics, no tracking and no third-party advertising. Your recipes, development log and settings are stored only on your device (local storage) and never leave it. You can delete them at any time in the app or by deleting the app.
The app does not collect data from anyone, including children.
We may update this policy; changes will be posted on this page.
