Without going into much detail, I needed to write a personal statement talking about events that took place in the course of three years, and Google maps storing my locations by the minute was very helpful. Example: I traveled to city A between two dates, I know I flew there then drove back. I knew I went to this coffee shop at a specific hour and stayed there for 43 minutes... Etc

My only wish is if I was self hosting all this and not relying on Google.
