Arca por DangerCat

Arca is a personal image organization tool I built for my own use. It saves right-clicked images into a self-hosted backend service I run on my own hardware.

Heads up: this extension is not currently useful to anyone but me.
The backend service it talks to is private — I haven't released it yet and may never, or may open-source it later once it's ready. If you install this extension today, every save attempt will show "Backend offline" and nothing will happen. No data will be transmitted anywhere.
