JustSpin Privacy Policy

This Privacy Policy describes how [Operator name] ("we") handles user information in the Android application "JustSpin" (the "App").

Information We Collect

The App handles the following information only to the extent necessary to provide its features. All of it is stored solely on your device.

• Training data: power (W), cadence (rpm), speed, and heart rate obtained from smart trainers and sensors connected via Bluetooth, together with workout records such as date, time, and duration
• Connected device information: names and identifiers of the Bluetooth devices you connect
• Settings: training preferences such as your FTP
• External service credentials: your Strava authentication token (stored in encrypted form) and your Intervals.icu credentials

The App does not collect:

• Location data (Bluetooth scanning is configured so that it is never used to derive your location)
• Advertising identifiers or usage analytics (the App contains no advertising, analytics, or tracking SDKs)

How We Use Information

The information above is used only to run, record, and review your training sessions, and to upload data to external services when you choose to do so.

Transfers to External Services

Only when you explicitly initiate an upload, the App sends your training data (a FIT file) to the following services:

• Strava: uploads are relayed through our API server (api.justspin.cc). The server only forwards the data and does not store your training data or authentication tokens.
• Intervals.icu: the App sends data directly to Intervals.icu.

Once transferred, the data is handled according to each service's privacy policy (Strava, Intervals.icu).

Data Storage and Deletion

• Training data and settings are stored in the App's private storage on your device and are deleted when you clear the App's data or uninstall it.
• Depending on your device settings, the App's data may be backed up to your Google account by Android's standard backup feature.
• To delete data already uploaded to an external service, please do so on that service.

Sharing with Third Parties

We do not share your information with third parties, except for the transfers you initiate as described above, or where disclosure is required by law.

Children's Privacy

The App is not directed at children, and we do not knowingly collect personal information from children.

Changes to This Policy

Any changes to this policy will be announced on this page. For significant changes, we will provide additional notice through appropriate means such as an in-app announcement.
