Is there anything open source like this?

I consider myself a strong privacy advocate but I just get so much benefit out of my Google location timeline that I cant bear to pull the plug.

It's my version of the pin up world map with everywhere I've been.

OwnTracks (http://owntracks.org/) could be a good starting point. It doesn't record your location out of the box, but there is additional software for that (https://github.com/owntracks/recorder).
