Privacy policy
Proof is a camera app that stamps photos and videos with the time, location and other details you choose. This page explains what data the app handles and what it does with it.
1. Permissions and why we use them
- Camera: to take photos, record videos and scan documents.
- Microphone: to record sound with videos. It is used only while you are recording.
- Location (only while the app is open): to print GPS coordinates, altitude and address on your photos.
- Photos / storage: to save your photos and videos to the "Proof Camera" album and to let you pick images to scan.
- Face ID (optional): to unlock the app if you turn on App Lock. See section 4.
2. Data that leaves your device
To turn GPS coordinates into a street address, the app sends the coordinates to the geocoding service built into your phone's operating system (on Android, provided by Google). The service returns an address that is printed on the photo. We do not store these coordinates and do not receive them ourselves. When your phone is offline, only the raw coordinates are printed.
Nothing else is sent anywhere. We do not have servers that receive your photos, videos, documents, location or the information you type.
3. Data stored on your device
Photos, videos and PDF files you create are saved only on your device, in your gallery or app folders. The company/project name, photographer name and notes you type are used only to stamp your photos. You can delete them at any time from your gallery, or by clearing the app's data or uninstalling the app.
Files leave your device only when you choose to share them using the share button, to the app you pick.
4. Face ID and face data
If you turn on App Lock, the app asks iOS to verify you with Face ID (or Touch ID, or your device passcode) through Apple's LocalAuthentication framework. This is optional and off by default.
- What we collect: none. The app does not collect, access, read, receive, store or transmit any face data (no face images, face maps, templates or facial geometry). Face matching is done entirely by iOS inside the Secure Enclave. The app only receives a yes/no result.
- Use: only to decide whether to unlock the app and your saved documents on this device.
- Sharing: none. Because we never receive face data, it cannot be shared with or sold to any third party.
- Storage and retention: none by us. Your Face ID data stays under Apple's control on your device and is never available to the app. You can turn App Lock off at any time in the app, or manage Face ID in iOS Settings.
- The app does not use ARKit face tracking, the TrueDepth camera, or any face detection or recognition feature.
5. Accounts, advertising, analytics and purchases
The current version has no accounts or sign-in, no advertising, no analytics or tracking and no in-app purchases.
If a future version adds any of these, we will update this policy before that version is released and describe what data is used.
6. Children
The app is a work tool and is not directed at children under 13.
7. Changes to this policy
When the policy changes, we update this page and the date at the top.
