if i were designing a recall program, here's how i would do it: it would take a screenshot every five seconds, OCR it, then run it through local quantized image recognition and word association neural networks, and then toss everything into a CryFS vault. when launching the recall program, you have to provide the password to unlock the vault so it can read and write to it. it can only run in the foreground (so you have to keep the window open for it to run, no closing it and forgetting about it) and it will display a status indicator in your system tray that provides a menu to pause or stop recording. afterwards, you can mark any text or region of the screen for redaction, and it'll redact it across all screenshots and delete it from the database; you can delete individual screenshots or entire periods of time; and there will be an easily accessible self-destruct option that shreds the database (i.e. overwriting it with random garbage 21 times before deleting it off the disk). this is all offline and the application will not request network access
i'm just making this up on the fly, so there are absolutely security and privacy considerations I absolutely forgot about, but this is the bare minimum i would like to see
that's true, but since this is a record of everything you've ever done, i feel this is the irreducible minimum for security. a separate password prompt would signal to the less technically-minded users that this is Serious
this is a design pattern i borrowed from Linux (my OS of choice). modern Linux apps require your explicit permission to run in the background, so most of them don't even bother with running in the background at all. that said, i suppose it can run in the background, as long as the status indicator is sufficiently noticeable, but you'd have to go into the settings and flip that switch yourself
i imagine that it would become a habit, or you'd set it to run on startup. my use case would be turning it on for specific tasks like research or shopping, where you might only later remember that that one thing you saw was actually really valuable
can a user-installed app do that?
