Terms of use

Trace, the sprint analysis app by Kongy Labs LLC. Effective 8 October 2026.

Agreeing to these terms

By using Trace you agree to these terms and to the privacy policy. If you don't agree, please don't use Trace.

Accuracy

Trace calculates times, splits and speeds from the frames you mark and the distance you enter. Its results depend on the video's frame rate, the camera angle and where the marks are placed. Use them for training, not for official records.

Not medical or coaching advice

Nothing in Trace is medical, physiotherapy or coaching advice. Sprint training carries a risk of injury; train within your limits.

Videos you add

Only analyze and share videos you have the right to use, and get permission before filming or sharing other people, especially minors.

Your data and your backups

Your data is stored on your device, not on Kongy Labs' servers, so we can't recover it for you. You are responsible for keeping backups; Trace gives you a way to download them. Only restore backups you trust.

Acceptable use

Don't try to break, overload or interfere with Trace or the website.

Kongy Labs' content

Trace's design, code, artwork and logo, and the Kongy Labs name, are owned by Kongy Labs LLC.

No warranty

Trace is provided "as is" and "as available", without warranties of any kind, express or implied, including that it will be error-free, uninterrupted, or that its measurements suit your purposes.

Limitation of liability

To the fullest extent the law allows, Kongy Labs LLC is not liable for injuries, lost data, or indirect, incidental or consequential damages arising from your use of Trace. Trace is free on the web, and our total liability for any claim is limited to zero dollars or the minimum the law allows.

Changes

We may update these terms. The new version will be posted on this page with a new effective date, and continuing to use Trace means you accept it.
