Privacy Policy

DeFace Privacy · App and Web

Short version: DeFace Privacy collects nothing. Your photos never leave your device. There is no account, no tracking, no analytics, no ads, no third-party servers contacted at runtime.

What data we collect

None. The app does not collect, store, transmit, or share any personal data, image data, device identifiers, usage statistics, crash reports, or any other information about you.

How your images are handled

Images you load into the app stay entirely on your device. All processing — pixelation, brush editing, face detection, saving — happens locally. Nothing is uploaded to any server. No image leaves your device unless you yourself send it via the system Share sheet.

Device permissions

iOS asks for permission only when you take a specific action:

Photo Library — when you tap Load to choose an existing photo.
Camera — when you tap Load → Take Photo to capture a new image.
Add to Photo Library — when you tap Save to write the result back to your photos.

No other data sources or sensors are accessed.

Network usage

The app does not contact any server while you use it. The face-detection model and runtime are bundled inside the app; nothing is downloaded at runtime. The web version (PWA) downloads the same bundled assets once from the same site (no third-party CDN) and then runs offline.

Third-party software

The app embeds the following open-source libraries and models. They run entirely on-device and do not connect to any service:

onnxruntime-web — face-detection runtime (WASM), MIT License, © Microsoft.
YuNet — face-detection model (OpenCV Zoo), MIT License.
Capacitor by Ionic — iOS app shell, MIT License.

Children

The app is suitable for all ages and does not knowingly collect any data from anyone, including children under 13. No accounts, no profiles, no communication features.

Changes

If this policy changes, the new version will be published at this URL with an updated date. Since no data is collected, changes will essentially only clarify wording.

Open source
