"The best way to avoid privacy breaches is not to formulate a detailed privacy policy; it's to reduce your capabilities so that you're unable to violate anyone's privacy."
No, however the description of the plugin should make it clear data will be uploaded to a third party server for recognition so the user can make a choice about that.
I don't find that clear at all. And this is also important to non-developers.
Also, for nearly all documents I ever need to scan, if they're important enough to require scanning, they're important enough that a third party should have nothing to do with them.
The majority of exceptions to the above being, ironically, documents without text, sketches, doodles, etc.
