Location data data brokers: ask them to remove your information

Location-data companies collect the movement history of phones, mostly through apps, and sell it for advertising, planning and investigations. The data is tied to a device rather than a name, but where a phone spends its nights and days can often be linked back to a person. These guides say where each company takes opt-out and deletion requests.
