Explicitly decided to keep Google Maps' location history activated on my device for precisely the same reasons. I'm yet to use it in court or something like that, but the argument about human memory resonates with me strongly - I've used location history many times to review e.g. on which day I was in some place or other few years ago. (Or once, years ago, to check how exactly did I get home after one party.)

RE people saying "just take a photo and use EXIF", that won't work because I don't know in advance what locations I will be interested in in the future.

Do you mean ex ante? A priori knowledge is that which is independent of experience, as in deduced from pure reason; it doesn't just mean 'in advance'.

Yeah, that's what I meant. Thanks for this correction, I didn't realize "a priori" doesn't mean what I thought it means.

(I edited the comment to use "in advance" instead of "ex ante" though.)

in a more formal or philosophical context you're right, but the more colloquial "in advance" usage is not wrong per se (hehe).
