I use mine with Microsoft Lens (I know, but one of their best products that doesn't spy on you) as a document scanner and then sync it to my document server paperless-ngx.
It can angle correct, color correct, and has good filters for b&w and greyscale that often make it look like a real document scanner if your phone has a decent camera.
Much better than drive or any of the open source options to be honest, sadly....
It doesn't request location access, it doesn't request contact or phone access, it doesn't require you to sign into a microsoft account, it doesn't constantly send data back home, etc... It only requests file permission and camera permission while you are using the app. A lot of apps harvest your data, and the entire Windows OS is built around harvesting your data and spying on your every click. This app doesn't seem to do that as far as anyone can discern.
May I recommend OSS Document Scanner + Syncthing? Both apps are FOSS and it looks to me like that they might be able to replace what Microsoft Lens does for you with the advantage that you are free of Microsoft software.
