3. Data Sharing and Third-Party Services
3.1 Wearable & Activity Integrations
- Telos integrates with Apple HealthKit, Google Health Connect, Strava, and similar services to sync your health data
- When you connect Strava, we may import activity details such as activity type, duration, distance, pace and start time so we can match them to your Telos training sessions and track your progress.
- We may also update certain activity metadata in Strava on your behalf (for example, renaming an activity to include the corresponding Telos session title and adding descriptive notes), but we do not post content to Strava without your explicit connection and consent.
- We use a 3rd party service provider to facilitate secure wearable data synchronization
- Your health and activity data is shared only with these authorized services and is subject to their respective privacy policies
3.2 Analytics Providers
- We use Firebase and similar analytics tools to track anonymized app events
- No personally identifiable information is shared with analytics providers
3.3 Service Providers
- We may share data with third-party service providers who assist in operating the Service (e.g., cloud hosting, payment processing)
- All service providers are contractually obligated to protect your data and use it only for specified purposes
- Certain data may be shared with third-party services you choose to connect (such as Strava) so that we can sync activities and, where enabled, update activity titles or descriptions to reflect your Telos training plan.
3.4 Strava
- If you choose to connect your Strava account, we sync your activity data to enable automatic workout matching and completion tracking.
We collect: activity type, duration, start time, and activity IDs from Strava.
Your Strava data is used only to match completed activities with your scheduled Telos sessions and to publish your completed Telos workouts to Strava.
We do not display your Strava data to other users or aggregate it across users.
When you disconnect Strava, we delete all Strava-related data within 30 days.
Your use of Strava integration is also subject to Strava's Privacy Policy and API Agreement
