Privacy Policy

Back to Home
Last updated: September 1, 2025

We care deeply about your privacy. This page explains what we collect, how we use it, and how long we keep it when you use our AI‑powered running analysis.

In short
  • Your video is processed briefly and stored temporarily.
  • Analysis results live only in your browser’s session and disappear when you close the tab.

1. Information We Collect

When you use the Service, we temporarily process:

  • Video files you upload to analyze your running form.

2. How We Use Your Information

We use your video files solely to provide the Service:

  • Analyze your running form using our AI models.
  • Generate a metrics report and personalized advice.
  • Create a processed overlay video with your performance metrics.

3. Data Storage, Retention, and Deletion

  • Deletion policy: Both the original and overlay videos are treated as temporary. While exact timing can vary, our policy is to delete these files shortly after your session ends.
  • Local results only: Analysis results are stored only in your browser’s sessionStorage and are lost when you close the tab.

4. Data Security

We use industry‑standard technical and administrative safeguards. All transfers occur over encrypted connections (HTTPS).

5. Third‑Party Services

We rely on Amazon Web Services (AWS) S3 for temporary file storage and processing. Their handling of data is governed by their own policies.

6. Children’s Privacy

This Service is not intended for individuals under 13. We do not knowingly collect information from children under 13.

7. Changes to This Policy

We may update this page from time to time. We will post any changes here.
