AirPosture - Privacy Policy

Effective Date: March 12, 2026 Last Updated: March 12, 2026

Relja Bulajic ("we," "us," or "our") built AirPosture ("the App") as a posture tracking application. This Privacy Policy explains what information the App collects, how it is used, where it is stored, and your choices regarding your data.

By using AirPosture, you agree to the collection and use of information as described in this Privacy Policy.

1. Information We Collect

1.1 Posture & Motion Data

Head motion data from Apple AirPods motion sensors (pitch, roll, yaw) used to calculate real-time posture scores.
Posture session summaries including start/end times, duration, average score, score distribution, and device name.
Daily statistics derived from session summaries (total time, average score, session count).
Streak data including daily streaks, quality streaks, weekly streaks, and protection freezes.

Raw motion samples are processed in real-time and stored temporarily on-device only. They are not synced or transmitted to any external service.

1.2 Posture Assessment Photos

If you use the posture assessment feature, the App captures or imports body photos (front view, side views) using your device camera or photo library. These photos are used for:

On-device body pose analysis using Apple's Vision framework.
AI-powered posture assessment (premium feature) where photos are transmitted to our AI provider for analysis (see Section 4).

Photos are stored on your device and synced to your personal iCloud account (see Section 3). You can delete photos at any time through the App.

1.3 Health Data (HealthKit)

With your explicit permission, the App may:

Write posture sessions as workouts and mindful minutes to Apple Health.
Read relevant health data to provide contextual insights.

HealthKit data is handled in strict accordance with Apple's HealthKit guidelines:

HealthKit data is never shared with third parties.
HealthKit data is never used for advertising or marketing.
HealthKit data is never transmitted to external servers.
You can revoke HealthKit access at any time in Settings > Privacy & Security > Health.

1.4 Social Profile Information

If you use social features, the following information is collected:

Display name (user-chosen, does not need to be your real name).
Friend code (randomly generated identifier for connecting with friends).
Avatar seed (random number for generating your avatar).
Posture statistics you choose to share (scores, streaks, session counts).

Social data is stored in Apple's CloudKit public database and may be visible to other AirPosture users you connect with. See Section 5 for details.

1.5 User Preferences & Settings

App settings and preferences (notification preferences, theme, calibration settings).
Subscription status and trial information (managed locally and via iCloud key-value store).
AI coaching conversation history (stored on-device, up to 5 exchanges per day).

1.6 Device Information

Device name is recorded with session summaries to identify which device a session was tracked on.
Device model and OS version may be collected by Apple through standard App Store analytics (see Section 6).

1.7 AI Coaching Interactions

When you use AI-powered coaching features (premium), the following data is sent to our AI provider:

Posture scores, session statistics, and streak data.
Body photos (for posture assessments only), resized to a maximum of 800 pixels and compressed (JPEG, 0.5 quality).
