+_OpenTracks_ is based upon Google _My Tracks app_ ([code](https://code.google.com/archive/p/mytracks/)).
 Initially, _My Tracks_ was initially released by Google in 2010 as [open-source software](http://google-latlong.blogspot.fr/2010/05/code-for-my-tracks-is-now-yours.html).
 In 2016, [Google decided to discontinue](https://support.google.com/maps/answer/6333516) _My Tracks_ and stopped distributing it via the Google Play store in April 2016.
 The [Plonk42](https://github.com/plonk42) conducted some maintenance work until 2016, so _My Tracks_ could still be used (based upon version _Google's MyTracks_ version 2.0.6).
