Syncthing on Android seems to use the “storage” system (not app-private data). I have some sensitive information I would like to sync with Syncthing, but not grant other apps with Storage permission access to it.
After quite a lot of searching, I am not at all clear what other apps have access to it.
I have a Pixel 4a with Android 11. I gather that on Android versions before 10 or 11, the answer is pretty much “all other apps with storage access”. I’m unsure if this has changed with Android 10 & 11. Perhaps apps built with legacy permissions still do? How can I tell? Would Syncthing ever support using app-private storage like the Nextcloud app does?
