These changes are designed to safeguard Strava's unique user experience and brand identity.
Impact on Users and Apps
Strava's API data sharing restrictions have significant implications for users and third-party apps.
Users who have granted third-party apps access to their Strava data can expect to see changes in how that data appears or is used by some apps as they adjust to the new privacy terms.
Many users are complaining about the sudden shift, feeling that restricting access to the API will kill the service. Some users are worried that they'll lose access to features like automatically updated leaderboards, personalized workouts, and "year in review" recaps.
Strava expects these changes to impact less than 0.1% of the apps on their platform.
Here are some examples of third-party apps that may be affected:
- Coaching and training platforms like Final Surge and TrainerRoad
- Data visualization tools like VeloViewer
- AI-powered analytics platforms
Strava is also prohibiting third-party developers from using data extracted from Strava users for training AI models, citing concerns about user control and privacy.

Policy Change Impact on Third-Party Apps
Strava's policy change has significant implications for third-party apps that rely on Strava data to provide features like automatically updated leaderboards, personalized workouts, and "year in review" recaps. These apps, such as VeloViewer and Final Surge, may have to find alternative means to offer these features.

The updated Strava API agreement prohibits third-party apps from displaying a user's Strava activity data to anyone other than the user themselves. This means that services like VeloViewer, which offers "new insights, engaging visualisations, motivational goals and in-depth analysis to your Strava data", will no longer be able to display user data to others.
Strava estimates that less than 0.1% of the apps on their platform will be impacted by this change. However, for small services that fill specific niches for end users, this change may be devastating. These services are often run by individuals with a passion for cycling, and the loss of access to Strava data could mean the end of their business.
