Unmark lets you paint over a watermark, logo, or unwanted object in a photo anderase it, entirely on your phone, with no internet connection required and nothing
uploaded anywhere.
Watermark removal uses a small, pure-Kotlin nearest-fill and smoothing algorithm.
There is no AI/ML model, no bundled weights, and no native code. See the project
README for how it works.
Features:
* On-device inpainting, no cloud processing, no network permission
* Manual brush selection with adjustable brush size
* Undo last stroke / reset mask, original photo is never overwritten
* Automatic metadata stripping (EXIF, XMP, possible C2PA) on save, with a scan showing
you what was found in the photo before it's gone
* Save result to your gallery or share it directly
* No ads, no trackers, no analytics, no account required
WhatsNew:
Removed automatic vendor watermark detection, it was unreliable. Batch process now works by drawing one watermark box on a preview photo and reusing it across the whole batch, instead of guessing a vendor's watermark position.
While you can download the APKs here directly, you should preferably use an F-Droid client so the app stays up-to-date on your device.
