Strava’s Flyby tool lets you revisit your workout, or the workout of people near you, to gain insights into your performance. It’s useful if you’re trying to see where you slow down or speed up during an activity, and how you fare against other people in your locality. By default, this data is kept private.
If you’ve enabled Flyby at some point and forgotten about it, you can go to the privacy settings page on Strava and select No One in the Flyby section to disable it.
Strava also periodically sends your followers notifications about your activity. You can disable this option, too, on the privacy settings page. Scroll down to the section labelled Sharing my activities with my followers and select Do not send these notifications.
