No. Background removal, object erase and every other edit run on your device. A photo only leaves your phone if you explicitly share or export it. See the privacy policy for details.

Yes: all editing tools are free and supported by ads. If you’d rather not see ads, a single one-time in-app purchase removes them permanently.

Almost never. The models that do the work ship inside the app (the U²-Netp cut-out, the tap-to-select network and the generative fill), so removing a background or an object works in flight mode. The one exception is the other cut-out engine, Android’s own ML Kit, which fetches its model through Play services the first time it runs; the bundled one is there for exactly that case, and the app falls back to it. Otherwise a connection is for ads, purchases and the consent form.

Fill in rebuilds the background where the object was, using the rest of the photo, so removing someone from a beach leaves beach. Erase cuts the object to transparency instead, which is what you want when you’re about to drop the result onto a different backdrop. The chooser is at the top of the Remove object panel and Fill in is the default; either way, undo brings the object back.

English, Polish, German, Spanish, French and Czech: the whole interface, not just the menus. It follows your phone’s language by default, and Settings has a picker if you’d rather pin one. Each language is listed in its own script, so you can always find your way back.

Yes, and a dark one, and it follows your phone unless you pin either in Settings. Dark is pure black rather than a dark grey, which on an OLED screen means those pixels are genuinely switched off; light is pure white so it stays readable in daylight.

Yes. The 14 looks in the filter lab are the app’s own colour matrices, exported from its source code and applied by your browser: not screenshots or approximations.

Yes. Photo count, layout, border width, corner radius and border colour all stay in the Grid panel for the life of the project. Swapping to another layout at the same photo count keeps each photo in its cell and re-fits it to the new shape. Dropping to a lower count removes the photos in the cells that go, as one undoable step.

Both. Turn the phone and the tool dock becomes a rail down the left edge with a folding panel beside it, so the photo gets the width. Tablets get the same layout with a larger canvas.

Android 8.0 (Oreo) and newer. Tap-to-select object removal asks for 2.5 GB of RAM or more: under that the app declines to offer it rather than risk being killed mid-edit, and the simpler selection still works. Background removal runs everywhere.

Chromis is Android-first. An iOS version may follow: let us know if you’d like it.
