With all of these apps, there's always the risk it eventually falls into the wrong hands.

I bought the pro version of a great scanning application years ago, only to have it eventually become malware as it exchanged hands over and over.

I'm guessing you mean CamScanner. Such a shame. Have you found a viable alternative?

I was CamScanner for me. Switched to Notebloc with Syncthing to get my scans out.

I've just used what's built into the OS these days. Not as good, but good enough post-covid where documents can be fully digitally executed.
