Android app privacy policy
Last updated 20 October 2026
This policy covers the OpenPixels app for Android (com.openpixels.app), as installed from Google Play or downloaded from openpixels.app. The website has its own privacy policy. OpenPixels is open source, so none of this has to be taken on trust — the source is at gitlab.com/openpixelsapp/OpenPixels and every claim here can be checked against it.
On Android, OpenPixels enlarges photos up to 8×, removes noise and JPEG artefacts, and processes several photos in one batch. Face restoration, colourising and background removal are not part of the Android app.
The short version: your photo is processed on your phone and saved back to your phone. It is never uploaded, because there is no server anywhere in this product that accepts an image. The app contains no analytics, no crash reporting and no advertising. Using it needs no account. The only network activity, unless you choose to sign in, is downloading the AI models the first time a feature needs them.
What the app never collects
- Your photographs, or anything derived from them — no thumbnails, no faces, no measurements. A photo is read from your phone, processed by the app on your phone's processor, and written back to your phone.
- Usage data. The app has no analytics, so there is no record of which features you used, how often, or what you produced.
- Crash reports and diagnostics. No crash reporter or telemetry library is included.
- Advertising identifiers. The app shows no ads and does not read the Android advertising ID.
- Location, contacts, or your photo library. The app does not ask for those permissions.
Permissions
The app requests one permission: internet access, used to download the AI models and, if you choose to, to sign in. It does not request access to your storage, photos or camera:
- You choose photos through Android's own picker, which hands the app only the photos you pick.
- “Take a photo” opens your phone's camera app, which hands back the picture you take. OpenPixels never controls the camera itself.
- Finished photos are saved to
Pictures/OpenPixels, and batch downloads toDownload.
What is stored, on your phone only
- The AI model files, downloaded once and kept so the app works offline afterwards.
- Your settings: the options you last used and your language.
- If you sign in, the sign-in session.
None of this includes your photographs, except the results you save. Uninstalling the app removes everything above. Photos you saved stay in your gallery until you delete them.
What our server sees when a model downloads
The models are downloaded from openpixels.app, our own server, not from a third party. Like any web server, it records standard access log lines for each request: the IP address, the time, the file requested and the user-agent string. The request carries no photo, no account and nothing about your device beyond that. These logs are used only to keep the service running, are not combined with anything else, are not sold or shared, and are rotated and deleted on a short cycle.
The optional account
Nothing in the app needs an account. There is an Account screen because accounts and credits are shared across our apps, and signing in lets you see that shared balance. Nothing can be bought in the Android app.
If you sign in, you choose one of three methods:
- Google: Google shares your email address, name and profile picture with our account server.
- A crypto wallet: your public wallet address identifies you.
- Nostr: your public key identifies you.
Our account server, at auth.openpixels.app, stores what that method provides, plus an account ID, your credit balance, and the history of credits added and spent. It is used only to run your account. It is not used for advertising, not sold, and not shared with anyone. No photograph, and nothing derived from one, is ever part of these requests. Our own servers are the only ones the app contacts.
Deleting your account
You can delete your account at any time:
- In the app: open Account (the person icon at the top), sign in, tap Delete account…, then Delete my account.
- Without the app: open openpixels.app/#/account in any browser, sign in the same way, and do the same.
- By email: write to hello@openpixels.app from the address you signed in with, or say which sign-in method you used.
Deletion takes effect immediately. Your sign-in methods are removed, and with them your email address, name and wallet or Nostr identity. The account itself becomes an anonymous record, with no name or email, that keeps its credit history, because that history is an accounting record. Any remaining credits are lost. The account is the same in all of our apps, so deleting it deletes it everywhere.
Children's privacy
OpenPixels is not directed at children under 13, and it collects no personal data from anyone who does not sign in.
Your rights
Regulations such as the GDPR and the CCPA give you rights to access, correct, export and delete the personal data a service holds about you. If you have never signed in, we hold nothing about you. If you have, write to the address below to exercise any of those rights, or delete the account yourself as described above.
Changes to this policy
If this policy changes, the date at the top of this page will be updated. If the app ever gained a feature that sent anything anywhere, it would be described here before the feature shipped, not after.
