Unmark

about

description

Unmark lets you paint over a watermark, logo, or unwanted object in a photo and erase 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
