Privacy Policy

Last updated: April 19, 2026

Calis League app and calisthenicsambition.com website

1. Introduction

This privacy policy describes how Calis League (hereinafter "we", "our" or "the App") collects, uses, stores and protects your personal data when you use our mobile application and website.

We are committed to protecting your privacy in accordance with the General Data Protection Regulation (GDPR - EU 2016/679) and applicable data protection laws.

2. Data Controller

3. Data We Collect

We collect the following categories of data:

3.1. Registration Data

• Email address: used to create and authenticate your account
• Password: encrypted and stored securely (never accessible in plain text)

3.2. Workout Data

• Exercises performed: exercise type, number of repetitions, number of sets
• Session history: dates and details of your workouts
• Quality scores: performance evaluations calculated by the app

3.3. Profile Data

• Username: freely chosen by you, displayed on the leaderboard

3.4. Body and Pose Data (Camera Usage)

The app's AI Tracker feature loads a web page hosted on our own website (calisthenicsambition.com) inside an in-app WebView. This web page uses your device's camera to provide AI-powered exercise form tracking. Here is how it works:

• Web content provider: The AI Tracker loads content from https://calisthenicsambition.com/counter/launcher.html, which is owned and operated by us (the same developer as the app). Although this web content is served from our website, it is governed by this same privacy policy.
• Technology used: The web page uses Google MediaPipe Pose Landmarker, an on-device machine-learning model that detects body pose landmarks (e.g., shoulders, elbows, wrists, hips, knees, ankles). The model also outputs a nose landmark used solely as a head-position reference point for pull-up repetition counting.
• No face data is collected: The app does not perform facial recognition, face identification, or create any facial geometry map. The nose landmark is a single 2D/3D coordinate used exclusively to measure vertical head displacement relative to the hands during pull-up exercises — no facial features, expressions, or biometric face data are analyzed or recorded.
• All processing is on-device: The MediaPipe model runs entirely in the WebView on your device using the device's GPU/CPU. No camera frames, images, video, or pose landmark coordinates are transmitted to any external server. The web page does not upload camera data — only the static JavaScript and ML model are downloaded from our website; all processing happens locally.
• Data transmitted to our website: The only data sent from the app to our website is your authenticated session token (so your workout can be saved to your account) and an exercise context parameter. No camera frames, video, images, or pose landmark coordinates are ever transmitted.
• No storage of pose data: Landmark coordinates are processed in real time within the WebView and immediately discarded after each video frame. Only the resulting exercise repetition count and quality score (numerical values) are saved to your account in our database (Supabase).
• No third-party sharing: No body pose, landmark, or camera data is shared with any third party, including Google. The MediaPipe model is loaded once and runs locally within the WebView — it does not phone home or transmit data.
• Retention: Since pose landmark data is never stored, there is no retention period. The numerical workout results (rep count, quality score) follow the same retention policy as other workout data (see Section 7).

3.5. Expert Athlete Review (Optional, Paid Feature)

The app offers an optional paid feature called Expert Athlete Review, which allows you to submit a recorded video of your exercise for personalized written feedback from an experienced calisthenics athlete.

• Strictly voluntary and user-initiated: Your video is only uploaded when you explicitly purchase and initiate a review request. No video is collected without your deliberate action.
• What is uploaded: A short exercise video recorded within the app (typically 10–60 seconds), containing only your body performing the exercise. No audio, location, or other identifying data is included.
• Who accesses the video: Only the founder of Calisthenics Ambition (an experienced calisthenics athlete with 10+ years of practice) accesses your video for the sole purpose of delivering your written feedback. No third party ever sees it.
• Storage: Videos are stored in a secured, access-controlled Supabase Storage bucket (encrypted at rest and in transit, EU/US region). Access is restricted via Row Level Security — only you and the coach can read your video.
• Retention: Your video is retained for a maximum of 90 days after your feedback has been delivered, then automatically deleted. You can also request immediate deletion at any time (see Section 10 and our account deletion page).
• No third-party sharing: Your video is never shared with, sold to, or accessed by any third party.
• Legal basis: Performance of contract — you explicitly purchase and consent to this service.

8. Data Sharing

Your data is never sold to third parties. It may only be shared with:

• calisthenicsambition.com (our website): the app's AI Tracker feature loads web content from our own website in an in-app WebView. The only data shared is your authentication session token and exercise context. No camera data, images, or pose landmarks are transmitted. This website is owned and operated by us.
• Founder (experienced athlete): if you purchase an Expert Athlete Review, the founder of Calisthenics Ambition (10+ years of calisthenics practice) accesses your exercise video solely to deliver your feedback. This access is strictly limited to your review request and no one else has access to your video.

• RevenueCat: in-app purchase management and entitlement verification
• Competent authorities: only upon legal request

9. International Transfers

Your data may be transferred to the United States (Supabase servers). These transfers are governed by Standard Contractual Clauses approved by the European Commission, ensuring an adequate level of protection.
