Privacy policy
Last updated 14 October 2026
Stamped is an iPhone app that makes passport, visa and ID photos. This page explains what it collects, and it is short because the app collects very little.
Your photos stay on your phone
Face detection, background replacement, cropping and the rule checks all run on your iPhone using Apple's on-device Vision framework. Your photos are never uploaded to us or to anyone else. Photos you unlock are kept in the app's own storage on your device until you delete them or the app.
What the app sends to our server
- A random device identifier. The app creates it on first launch and keeps it in your iPhone's keychain. It is your account; it is not linked to your name, email address, phone number or Apple ID.
- Purchases. Which pack you bought and when, so it can be applied to your account and restored later.
- Unlock records. A random photo identifier and the document type (for example "US passport") for each photo you unlock, so a photo you paid for is never charged twice. Not the photo.
- Usage events. Which steps of the app you reach, such as "chose a document" or "opened the purchase screen", with the document type. We use them to see where the app is confusing. They contain nothing personal.
Purchases
Payment is handled by Apple. We use RevenueCat to confirm purchases with Apple; RevenueCat receives the random device identifier and your App Store transaction details. See RevenueCat's privacy policy.
Support messages
If you write to us through the support page, we store your message and, if you give one, the email address to reply to. We use it only to answer you.
What we do not do
No advertising, no tracking across apps or websites, no selling or sharing of data, no analytics SDKs. Nothing you do in the app is used to train any model.
Where it is stored
Our server and database run on Cloudflare.
Deleting your data
In the app, open Settings and tap "Delete all my data". That removes your account, unlock records and usage events from our server immediately, and the photos stored in the app on your phone. We keep the record of each App Store purchase, which holds only the random identifier and the product, because it is what stops one purchase being granted twice. You can also delete the app, which removes everything on the phone.
Children
Parents use Stamped to make photos of their children for passports. Those photos are processed on the phone like any other and are never uploaded.
