None. This version (1.0) of Washday Lab has no account system, no login, no advertising SDK, no analytics or crash-reporting SDK, and no in-app purchases. Its only dependency is the UI toolkit itself. We do not collect your name, contact details, location, device identifiers, usage data or any behavioural profile, and we never sell, share or transfer such data because we never have it. The app behaves identically in airplane mode.

None. Washday Lab requests no permission at all - not for the camera, not for the photo library, not for location, not for motion or body sensors. Garments, stains, care labels and outcomes are drawn and explained inside the app; you never photograph or scan anything.

Your save is one small file in the app sandbox on your own device: your settings (language, text size, interface scale) plus the last ten runs. A run stores only the four options you picked for that garment - scores, maxima and consequences are recalculated from the current rule set every time you open the record, so no second copy of that information is kept. The file never leaves the device, it is not backed up to our servers (we have none), and removing the app deletes it.

Washday Lab contains no chat, no user-generated content, no advertising and no purchases, and it processes no personal data of any kind.

We may revise this policy; changes are announced by updating the "Updated at" date above. Continuing to use Washday Lab after an update means you accept the revised policy. If a future version were to collect data, this page would be updated - and the App Store privacy label - before that version ships.
