Data controller

4h/world is operated on a personal basis. For any question about your data, contact us at contact form.

Data collected

This site runs without a user account and without advertising trackers. The data processed is the following:

• Anonymous browsing data: pages visited, session duration, device type, collected via Vercel Web Analytics in an aggregated, non-personal form.
• Data entered in forms: the sporting performances (times, splits) you enter voluntarily, as well as the first name, last name and email address you provide in the contact form or a video analysis request.
• Data sent with a video analysis request: the date and location of the race, the lead leg, a link to the video, and any optional comment you add.

Video analysis requests

The video analysis form, available from the race entry page, lets you send us a link to a race video along with your first name, last name, email address, and the date, location and characteristics of the race. This information reaches us by email and is used solely to carry out the requested analysis and reply to you.

Sending the form requires your explicit consent, collected via a checkbox before submission. This consent covers two distinct uses: viewing the video for analysis purposes, and publishing the corresponding performance in the site's database. The published entry may include your first and last name, the date and location of the race, the recorded times and the video link.

The video itself stays hosted on the platform of your choice: we only keep the link. You can delete it or make it private at any time, independently of us.

If the athlete filmed is a minor, the submission must be made by a legal guardian or with their prior agreement.

You can withdraw your consent and request the removal of the published performance at any time, without giving a reason, via the contact form.

Vercel Web Analytics

This site uses Vercel Web Analytics, a cookieless audience measurement tool. It does not set any cookie on your device and does not create an individual profile. The metrics collected are fully aggregated and anonymized.

No prior consent is required for this collection, in line with CNIL recommendations for exempted audience measurement tools.

Cookies

This site does not use tracking or advertising cookies. No cookie consent banner is required.

Data sharing

No personal data is sold, rented or transferred to third parties for commercial purposes. Anonymous browsing data is processed by Vercel Inc. under its own privacy policy. Messages sent from the site's forms, including video analysis requests, are routed through Resend, our email delivery provider, under its own privacy policy.

Your rights

As the site has no user account, these rights apply only to the data you send us through a form:

• Access and rectification of the information you provided
• Erasure of this data, including the removal of a published performance
• Objection to processing or withdrawal of your consent, at any time

To exercise these rights, contact us via our contact form. You can also file a complaint with the CNIL.
