Teen Max Height Privacy Policy
Teen Max Height is designed for private, local height tracking with no account, no ads, and no tracking.
Teen Max Height helps people record height measurements, view growth trends, keep optional family context, complete daily growth-support check-ins, read educational guides, and export PDF reports. Its core data is stored on your device and is not sent to a QnSub account or backend.
Data stored on your device
Depending on the features you use, Teen Max Height may store the following locally:
- Profile information such as a profile name, birth date, reference selection, profile role, optional guardian name, optional family links, optional target height, and notes.
- Height records including height, date, measurement source, confidence, quality score, posture cue, analysis inclusion, and notes.
- Daily check-ins including sleep hours, protein meals, calcium-rich servings, activity minutes, outdoor minutes, and optional notes.
- Preferences such as display units, voice guidance, haptics, and other local app settings.
Camera and LiDAR access
On supported devices, Teen Max Height uses the camera, ARKit scene depth, and person segmentation during a live LiDAR measurement. These signals help estimate height and show framing, distance, confidence, point-count, and quality guidance.
Raw camera frames, depth frames, and point clouds are not retained or uploaded to QnSub. Manual measurements do not require camera or LiDAR access.
Accounts, analytics, ads, and tracking
Teen Max Height does not require a QnSub account. The app does not include advertising SDKs or third-party tracking SDKs, does not track you across apps or websites, and does not send core profile, measurement, or check-in data to a QnSub server.
PDF exports and sharing
You control when a height-history PDF is created and where it is saved or shared. After an exported file leaves Teen Max Height, the destination app, service, recipient, or storage provider handles it under its own privacy practices. Delete exported copies separately wherever you placed them.
Apple services, purchases, and backups
Apple processes App Store downloads, purchases, refunds, payment details, and Apple Account information. QnSub does not receive your payment card or Apple Account credentials. Local app data may be included in device or iCloud backups depending on your Apple settings.
Teen and family profiles
The app can store information about teens and family members locally. A parent or guardian should supervise use by a minor and decide what information to enter or export. Teen Max Height does not create an online profile for a child or knowingly collect that information on QnSub servers.
Deleting your data
You can remove records using controls available in the app, use the reset option in Settings for a clean local state, or delete Teen Max Height to remove its local app container. Exported reports and device backups must be deleted from their own locations.
Health and medical boundary
Teen Max Height is an educational measurement and tracking tool. It does not diagnose growth delay, prescribe supplements, predict adult height, or promise additional height. Consult a qualified pediatric clinician for health, growth, nutrition, or development concerns.
