ShowerLab Privacy

ShowerLab is designed to work locally on your device. It does not require an account and does not operate a developer-controlled backend service for storing your sessions or Apple Health data.

• Apple Health heart rate data.
• Apple Health heart rate variability data.
• Apple Health sleep data.
• Apple Health workout data.
• Apple Health resting heart rate data.
• Thermal session details you save in the app.
• Optional notes you attach to sessions.
• Optional before and after energy ratings you enter in the app.
• Optional before and after stress ratings you enter in the app.

• Save your session history locally on your device.
• Calculate recovery and trend insights inside the app.
• Show before and after comparisons for heart rate and HRV.
• Add sleep, workout, and resting-heart-rate context around saved sessions.
• Power charts, summaries, and recent activity views.
• Let you optionally export saved sessions as a CSV file.

ShowerLab stores session history and Apple Health-derived analysis locally on your device.

The app may send limited in-app analytics events to Firebase Analytics so aggregate product usage can be measured. These events can include app opens, key screen views, session-save actions, session deletions, and CSV exports.

ShowerLab does not transmit Apple Health samples, saved session notes, energy ratings, or stress ratings to a developer-controlled server. It does not use advertising SDKs or cross-app tracking SDKs in the current version.

ShowerLab reads Apple Health data only after you grant permission. It is read-only with respect to Apple Health.

• It reads heart rate.
• It reads heart rate variability.
• It reads sleep data.
• It reads workouts.
• It reads resting heart rate.
• It does not write data back to Apple Health.

You can revoke Health access at any time in the Apple Health app or iOS Settings.

Saved ShowerLab sessions are stored locally on your device using Apple system storage.

If you choose to export sessions, ShowerLab generates a CSV file locally and hands it to the iOS share sheet so you can decide where it goes.

Resetting local sessions inside ShowerLab removes the app's saved session history from that device. It does not delete data from Apple Health.

ShowerLab does not track you across apps or websites. It does not share data with data brokers or advertisers.

Firebase Analytics is used only for aggregate product measurement, not for advertising or cross-app profiling.

Firebase Analytics may use an app instance identifier to measure aggregate usage. ShowerLab does not map that identifier to an in-app user account because no account system exists.

ShowerLab is not directed to children.

If ShowerLab's data practices change in a future release, this policy and the App Store privacy answers will be updated before release.
