Yes. Fitness trackers and running apps often share more than you realize.
The problem:
In 2018, Strava’s public “heatmap” accidentally revealed secret military base locations because soldiers were tracking their runs.
What fitness apps share:
- Your running/cycling routes
- Where you start and end (usually home)
- When you exercise
- Your daily patterns
Privacy risks:
- Public profiles show where you live
- Predictable routines make you vulnerable
- Data gets shared with third parties
How to protect yourself:
- Use private profiles, not public
- Enable “privacy zones” around home/work
- Disable route sharing
- Check who can see your activities
- Consider offline-only tracking
Many fitness apps have privacy settings — but they’re often off by default. Review them.
