1. Publisher and game operator

  • Site name: Pronos Biathlon
  • Nature of the service: a free biathlon prediction game and season tracker.
  • Contact: contact@pronosbiathlon.fr
  • Publication director: the administrator of the Pronos Biathlon website.
  • Data controller: the publisher of Pronos Biathlon, reachable at the contact address above.

The Pronos Biathlon game may also be presented and distributed within the Biathlon Live editorial environment. Pronos Biathlon remains the operator of the game and accounts, as well as the party functionally responsible for game data. Biathlon Live provides the editorial environment and distribution for this version. In the current architecture, this access does not transmit account data, predictions, scores, badges or notifications to Biathlon Live.

2. Hosting

The web application is hosted by Vercel Inc.

Authentication, the database and server functions are provided by Supabase Inc. Encrypted backups are stored outside the Supabase project as private GitHub Actions artifacts.

3. Intellectual property

The text, visuals, logos, layouts, graphic design and content specific to the Pronos Biathlon game are protected by applicable intellectual property rules.

  • Any reproduction, adaptation or distribution, in whole or in part, without prior authorisation is prohibited.
  • The names of biathletes, brands, social networks or competitions mentioned on the site remain the property of their respective owners.
  • The Biathlon Live brand, logo, visual design and editorial content remain the property of their respective owners.
  • Avatars are unofficial editorial illustrations of biathletes. They are not official assets and do not imply any affiliation with the IBU, the athletes or their representatives.
  • Content published in the community area must respect third-party rights and the spirit of the game.

4. Personal data and purposes

Pronos Biathlon processes only the information needed for accounts, the game, requested notifications, support and service security.

Account and profile Email, username, avatar and preferences

Your email is used for authentication and account security. Your username, avatar, favourites and preferences configure your player experience.

Public game Predictions, scores, ranks and badges

Submitted predictions, usernames, scores, standings, badges and some statistics are visible to other players. Email addresses and passwords are never public.

Support and security Messages, technical logs and abuse prevention

The form retains the information submitted. Restricted logs protect the service; abuse prevention uses a pseudonymous SHA-256 fingerprint of the network address, never the raw address.

  • Notifications: on the Pronos Biathlon version, when this feature is available and with your explicit consent, a Web Push endpoint and its technical keys are stored for this device. Web Push is not offered in the Biathlon Live environment. Internal notifications remain accessible in the site’s notification centre on both versions.
  • Required information: an email, username and password are needed to create an account. An email, subject and message are needed to use the support form; a username is optional there. Favourites and, on the Pronos Biathlon version, Web Push are optional.
  • Legal basis: depending on the processing, performance of the requested service, the legitimate interest in securing and administering the service, or your consent where required.
  • No sale: personal data is neither sold nor rented.
  • Automated decision-making: automatic point calculations apply only the game rules and have no legal effect.

5. Visibility, recipients and providers

Private account data is accessible only to the user and to strictly necessary administration functions. The game information described above is public by nature.

  • Vercel: application hosting and delivery.
  • Supabase: authentication, database and server functions.
  • Brevo: delivery of transactional registration confirmation and account recovery emails.
  • GitHub: encrypted backups in private artifacts with a limited retention period.
  • Web Push services: the service chosen by the browser or operating system, including those provided by Google, Mozilla, Apple or Microsoft, receives the technical data needed for delivery.
  • External resources: the browser may load fonts, flags and images from Google Fonts, cdnjs, FlagCDN or public IBU sources.

Some providers or technical services may process data outside the European Economic Area, depending on their infrastructure and the applicable contractual safeguards.

6. Retention and account deletion

  • Active account: account and profile data is retained for as long as the account exists.
  • Deletion: users can delete their account from My profile. Their identity, profile, preferences, Push subscriptions and personal badges are deleted.
  • Sporting history: previously published predictions, scores and standings are retained under the identity “Deleted user”, without a link to the former account.
  • Contact: messages are retained while the request is being handled, then for the limited period needed for administrative follow-up.
  • Security: anti-abuse counters operate in 24-hour windows. Private audits are retained for the period needed to ensure the service’s security, integrity and traceability.
  • Backups: daily encrypted backups are retained for 14 days; weekly and pre-competition backups for up to 56 days. Deleted data may remain in these copies until they expire.

7. Cookies and local storage

The site currently uses neither audience analytics nor targeted advertising. It uses technical storage needed to provide the requested functions:

  • Supabase authentication session;
  • temporary profile and calendar cache to speed up display;
  • on the Pronos Biathlon version, the state of PWA installation guidance and Web Push;
  • on both versions, preferences and the state of the internal notification centre;
  • a local contact-form cooldown marker, without a copy of the message or email.
No advertising consent: this storage is limited to the service and its security. If a non-essential tool is added, this page and the consent mechanism will be updated before it is enabled.

8. Your rights

Depending on the processing concerned, you may request access, rectification, erasure, restriction or portability of your data, or object to processing.

  • To exercise a right or ask a question: contact@pronosbiathlon.fr
  • Full account deletion is available directly in My profile.
  • On the Pronos Biathlon version, consent to Web Push can be withdrawn at any time from My profile settings without affecting access to the game. Web Push is not offered in the Biathlon Live environment.
  • You can visit the CNIL website and lodge a complaint if you believe your rights are not being respected.

9. Liability

Pronos Biathlon endeavours to provide information and content that is as reliable as possible. Despite this care, errors, omissions, temporary unavailability or delays in updates may occur.
