> using SQLite so... not ideal for people who like security
Just to point out, using SQLite does not necessarily mean it isn't secure; you can add security and encryption into SQLite, if that is appropriate to your use-case - and you can be bothered to do so[1]. Otherwise, using SQLite is precisely as secure as using Excel, Word, Libre Office or any of the other programs that Recall is effectively spying on.
I note that blog does not say which users can access the database: there is obviously nothing wrong with being able to access the log of your own interactions, it is only an issue if other users can. If it is capturing passwords (and demonstrably so, other than as a row of asterisks in all the screenshots it is taking), that makes it more desirable to keep others out, so access control is a Good Thing.
