Google some time ago deleted all my 13 years of location history while attempting to migrate it to local storage on users phones. I used it to keep track of business expenses for tax and had to collect the data someway else. Plus lost a lot of places i had kept track of in foreign countries visited. Desaster that showed I should not rely on them. Made that mistake there while self hosting and self backuping the whole other stuff. Oh well.
