What’s your risk model here? Google are not manually or automatically inspecting the contents of your spreadsheets in order to profile you and show you better-personalised ads. Not enough people have such a spreadsheet for it to be worth it for them, I’m sure - and they also probably already know approximately how wealthy you are. Unless you’re under investigation for fraud or something, I doubt the government could get much use out of being able to access your financial spreadsheets via Google compared to the information they already get directly from banks etc. So that only really leaves criminals (for whom I still can’t see a great incentive to read your spreadsheets), and I also don’t really think your Google account is much less secure than your computer’s local storage (if that’s the other place you would keep it)

We’ve learned over and over that tech companies do things which seemingly make no sense to us, but do to them. Not being able to imagine it is not sufficient. Nothing is deleted anymore as well, in hopes it will be useful later.

That said I don’t see a huge risk here, unless combined with lots of other data. Would probably avoid though.

I simply want minimal exposure of my personal data since I don't want to go through life thinking about risk models. Not only is it time consuming, but my creative juices simply don't flow when it comes down to exploiting people (nor do I want them to flow in that direction).
