If you’d like to see what data your phone has been collecting about your movements here’s how:

   For iPhone:

You can see what Apple refers to as your ‘Significant Locations’ by going to:

Settings > Privacy > Location Services >

Scroll down and select System Services > Significant Locations.

You will need to prove it’s you before being given this info e.g. by fingerprint scan, Face ID or typing in your passcode.

   For Android:

You can see what is referred to as ‘Your Timeline’ by:

Opening the Google Maps app.

Clicking on the menu (3 horizontal bars, top left)

Selecting ‘Your Timeline’.

At this point you may get an on-screen permissions message about turning tracking on or off.
