YOUR PRIVACY
Updated September 2026
Training activity and Form Lab
Your training sessions and summaries you explicitly save are stored privately with your account until you delete them. You can save up to 250 activities. Form Lab analyzes video pixels in your browser; it does not upload the selected clip or pose frames. A saved review includes the movement, working leg, duration, tracking coverage, estimated knee-bend range, and any measured reference angles. These are client-generated educational estimates, not clinical measurements. Google’s AI model and runtime download on demand; its library may send performance and utilization metrics. Read the library privacy notice. Clips sent separately through the feedback submission form are uploaded and follow the retention policy below.
Your account and billing
Clerk provides KneeRange account creation, email verification, sign-in, and password recovery. Your credentials are handled by Clerk. KneeRange stores your account identifier, email, Stripe customer reference, and membership status. Stripe processes payments; KneeRange does not store your full card details.
Owner notifications
When email alerts are connected, Resend sends KneeRange an operational notification when a paid membership starts or a video upload finishes. The notification includes your account email and an event reference. Video files, submission titles, notes, and feedback are not included in these emails.
Your videos and feedback
Submitted clips, their titles, notes, and feedback are stored privately and are accessible to your account and the KneeRange site owner. They are not published in the library or used in marketing through this service. You can delete each submission from Your videos.
Clips are automatically made unavailable after 90 days, and the service removes expired clips during submission activity. Temporary backups or provider logs may persist according to the hosting provider’s policies. Keep your own copy.
Progress and website services
Saved videos and playback progress are stored with your membership account. The hosting service receives technical request data needed to run the site. Fonts are delivered by Google Fonts. KneeRange has not added advertising trackers.
