Traccar is relatively easy to set up, for those who might be interested in ditching Google for location history altogether.
During a bout of Degoogling I‘ve imported my Google Location History Takeout into php-owntracks-recorder and used it happily with the OwnTracks app on my phones.
About a year ago I’ve replaced it with PhoneTrack running on my NextCloud - while keeping the OwnTracks app as a client.
These days, I want to check out Traccar and how it compares to PhoneTrack. I believe Traccar can also work with OwnTracks data. So if the Traccar client doesn’t behave, it’s a nice alternative.
