Assuming these tools work, you should probably have them set up to auto-delete collected data at least every 3 months:
Google collects a staggering amount of personal data about its users — far more than you might even realize. The company records every search you perform and every YouTube video you watch. Whether you have an iPhone ($699 at Apple) or an Android, Google Maps logs everywhere you go, the route you use to get there and how long you stay — even if you never open the app. When you look closer at everything Google knows about you, the results can be eye-opening, and maybe even a little unsettling. Thankfully, there’s something you can do about it.
I say “assuming these tools work” because we have to trust that Google does not just hide the data from us after 3 months – but actually deletes the data.
