Control who can see each activity and hide sensitive details.
Every activity has an audience, which defaults to Followers:
Set the default for new activities in Settings → Privacy, and change any single activity from its detail page. If your account is private, activities set to “Everyone” are shown to your followers only.
In Settings → Privacy you can hide heart rate, pace/speed, or power from other athletes. These are hidden wherever others view your activities — you always see your own full data.
Turn on Hide start & end of my routes and choose a radius. On activities other people can see, the map is trimmed near the start and finish so sensitive locations — like your home — aren't revealed. On your own view, the full route is always shown.
These controls apply to activities you sync from connected devices. Your public athlete profile and official race results are separate and remain publicly viewable.
