If you've enabled Google tracking by default it already records everything, logged to our private timeline ("Private": just between me, Google, the NSA, and every hacker in China and Russia.) Download the Google data file, convert it via a free online converter to something Strava recognizes, presto. Restored ride log.

When I switched from iPhone to Android in December 2017 I decided to enable Google maps timeline tracking by default. I figured it would help serve as an objective witness in case I was hit by a car, deer or something else happened and I was unconscious. Sure enough, it was handy last May when I was hit by a car. It confirmed my version of events -- my direction of travel, etc.

It's also handy for automatically logging all my many medical appointments in case the info is needed in court. It logs the specific hospitals and clinics I've visited. Occasionally I need to add or correct some minor info (specific clinic or doctor name). But it eliminates a lot of he said/she said.

Google data can't be faked by the user. It can be downloaded and the downloaded file can be edited, modified or faked. But not the original recorded by Google.

I figured there's no harm in enabling tracking by default. I already log all my exercise activities anyway.

If I was still a journalist and wanted to protect my sources I'd just leave the phone at home or the office. I still have my old iPhone, and by default Apple was a bit more respectful of user privacy. We have to choose to install Google apps and enable tracking. With most Android phones there's no real choice -- Google is installed by default and we're being tracked in some way whether we enable or disable tracking.
