Privacy Policy - Postura (Posture & Wellness)

Last updated: 2026-07-16

1. Summary

Postura is a posture-correction app that uses your AirPods' motion sensors. It detects forward head tilt and reminds you to sit up straight, with a 90-day program. The data you enter is stored locally on your device. The app only collects anonymous usage data (screens viewed, actions taken) to improve the experience.

2. Data collected

Postura stores your data exclusively on your device via SwiftData (a local database encrypted by iOS). It is never sent to a developer server, never shared with third parties, never used for advertising. It only leaves your device if you export it yourself or through your personal iCloud backup. Deleting the app permanently erases all local data.

Anonymous usage data

We use PostHog to improve the app. PostHog only collects anonymous events (screens viewed, usage actions), the app version, device type and iOS version. This data is tied to a random, locally generated identifier with no link to your identity. PostHog never receives the content you enter.

3. Permissions

The app requests only the following permissions, at your initiative:

Motion & Fitness (your AirPods' motion sensors, to detect your posture): no camera is used.
Notifications (posture reminders and progress milestones).

You can revoke each permission at any time from iOS Settings. The app requests no other permission: no camera, photos, microphone, location, contacts or HealthKit.

3bis. Health disclaimer

Postura is not a medical device. The app helps you become aware of your posture using your AirPods' motion sensors; it makes no diagnosis and does not replace professional medical advice. If you experience persistent back, neck or shoulder pain, consult a healthcare professional.

4. Third-party services

The app uses PostHog (posthog.com) for the anonymous usage analytics described above. Data is hosted in Europe (EU) and processing is GDPR-compliant. PostHog receives no health data, no personal data and no information that could identify you.

No advertising tracker, no social network integration, no third-party monetization SDK.

5. Your rights (GDPR)

Since your data is stored locally on your device and no personally identifiable data is sent to our infrastructure, we hold no data about you. You exercise your rights of access, rectification and erasure directly from the app or by uninstalling it.

6. Children

The app is not intended for children under 13.
