Strava offers several different features to help you manage your privacy. Most privacy settings are located on your personal settings page, but some are specific to individual activities or athletes.
Enhanced Privacy Mode
Enabling Enhanced Privacy allows you to manage who can follow you and see certain details about your activities. More details
Flyby is a Strava Labs tool that lets you playback your activity, as well as those near you, on a map and timeline. If you do not want other athletes to see your activities that appear in Flybys, you can choose to opt-out of this feature entirely. You can opt-out by checking the "nobody" button located in the Flyby section.
Training Log Sharing
The Training Log collects all your training in one place and is visualized to show your progress and highlight important stats. You can choose to make your training log public from your Strava settings page OR from the Training Log page.
If you have enhanced privacy on, an athlete must be following you in order to view your public training log.
A privacy zone will hide the portion of your activity that starts or ends in your zone from all athletes. More Details
Private Activities and Private Uploads
You can make an activity completely private on Strava by default or on an individual basis. You will be the only person who can see this activity on Strava. More Details
Group Activity Enhanced Privacy
Enable Group Activity Enhanced Privacy to ensure only you and those in your network will see you were part of a group activity. More Details
Hide from Segment Leaderboards
Your new activities will not appear on public segment leaderboards. This setting does not alter past activities, and you can change this on individual activities at any time.
Much like a private activity, the segment efforts from your activity will still show up on the My Results" leaderboard, but not on the !"All Time" or other leaderboards.
Strava Metro & Heatmap Opt-out
You can opt-out of contributing your anonymized public activity data to Strava Metro and the Heatmap by unchecking the box in this section. You can read more about the benefits of contributing your data here.
Manage Followers and Block Athletes
From your profile page, you can easily manage your current followers from the "Following" tab. More details
