Google sets a pretty good standard over at https://myactivity.google.com/ IMO. But yeah the whole passive data collection e.g Wifi networks done the Street View cars, as one example, bears scrutiny. Likewise Android
How do you know that that's actually all data Google holds on you? Facebook has a shadow profile for every one of its users, one whose contents you cannot access. There's no technical reason Google can't build one, and they have been deceptive in how they collect your information in the past https://apnews.com/ef95c6a91eeb4d8e9dda9cad887bf211
I don't disagree with you, that was deceptive, but man, I could so see myself making that blunder; the developer meant they won't be stored by the Location History tool, whereas the users reasonably read it as meaning by Google.
