Privacy
Short, because there is not much to say.
Your photos
They are never uploaded. Every step — decoding, face detection, segmentation, cropping, the print sheet and the download — happens in your browser on your own device. There is no server that could receive a photo, because this site is static files.
Nothing is stored either. Close the tab and the photo is gone; there is no history, no account and no local database.
What this site collects
No analytics, no cookies, no tracking pixels, no advertising network, no fonts or scripts loaded from anyone else's server. The page's Content Security Policy blocks connections to other origins, so even an accident could not send anything.
Our host serves the files and, like any web host, sees the ordinary request records that involves.
The iOS app
The app is a separate product with its own policy, which covers the App Store purchase flow that this website has no equivalent of: the app's privacy policy and terms of use.
