I've started keeping a log of all information I provide to a company: addresses, phone numbers, names, social security number, etc... I started doing it just to keep track of everywhere I need to update next time I change address, phone, cards, and emails at the same time[1], but it's been eye opening to watch the list grow.<p>I think of it as something like a reverse password manager; instead of "here's a website, what's my data", it's "here's a bit of information about myself, who has it?"<p>It's a pain keeping that list updated but at this point I'm so hooked on being able to see my personal info leak out into the world bit by bit that the friction is worth it.<p>I'm still trying to figure out what I should do with the data I have on myself, if anyone has any suggestions.<p>[1] That situation seems sketchy seeing it written down like that, so just want to explain that it's because I moved to a different country (address, phone, credit cards) and away from gmail at the same time.
