When you take a virtual bib, the race organizer sends us your name, email, bib, distance and, for the medal, your postal address. The organizer remains responsible for this data; we use it on their behalf, to sign you in, let you run and publish your results.
Your GPS position, every second, only between the start and the finish of a run you start, screen locked included. It measures your distance and time, and plays the announcements at the right places on the course.
At the finish, the app sends the recorded route, your time, your splits, the announcements played and a technical log (battery level, phone model and version, app version) so we can check the measurement and fix problems.
Each time you sign in, we note the date of your last visit and your phone model, so the organizer knows who installed the app.
Some announcements call you by your first name or bib, or say your time. Their text may be written by an artificial intelligence (Anthropic’s Claude, or Llama on Cloudflare Workers AI) and their voice made by ElevenLabs or Google Gemini. To write it, the AI receives your first and last name, bib, town and the current weather; the voice only receives the words to say. None of these services receives your email or your position.
To mention the weather, the app sends a position rounded to about a kilometre; we pass it to Open-Meteo and do not keep it.
If you send a selfie from the “Your race photos” page, we send it, with the organizer’s photos of the place, your bib and the race’s name, to Google (the Gemini image model, through Cloudflare) to make a picture of you in the race. You agree each time you send one; the page shrinks the photo and strips where it was taken before sending.
Your selfie and the picture made stay private: only you see them, until you choose to show the picture on your result page. You can hide or delete it at any time.
A race’s results and your certificate show your first and last name, bib and official time, like the results of a road race, and the race photos you choose to show.
The site, the database, the files and the emails run on Cloudflare. App updates come through Expo, with no personal data. The pages load their fonts from Google Fonts. There is no advertising, no audience measurement and no sale of data.
A sign-in code expires after 15 minutes, a sign-in after 180 days. Your runs and their routes are kept while the race and its results are online, or until you delete them.
In the app, “Delete my data”, at the bottom of your race screen, erases at once your runs, their GPS routes, the announcements written for you, your photos and the pictures made from them, and your sign-ins. Your entry (name, email, bib, address) stays with the organizer: write to them, or to us, to remove it.
You can also ask us for access to your data, its correction or an export, and complain to the CNIL (cnil.fr), the French data protection authority.
The organizer area records the email of each member of a race team, to sign them in by code, and the messages sent through the organizers page form, to answer them.
