18+At OddScore, we place great importance on the protection of your personal data.
This privacy policy explains what data we collect, why we use it, and what your rights are regarding that data.
Personal data collected on OddScore is processed under the responsibility of Créacité, a business incubator (association under French law, "loi 1901"), 11 route de la Fédération, 67100 Strasbourg, France — SIRET 479 179 327 00040, under the Contrat d'Appui au Projet d'Entreprise (CAPE) entered into with Pierre Filstroff, the OddScore project lead.

When using OddScore, certain data may be collected in order to allow the service to function.
The data collected is used in order to:
Depending on its purpose, a processing activity relies on one of the following legal bases under Article 6 GDPR:
OddScore uses certain third-party services necessary for the operation of the platform.
OddScore uses no advertising cookies, no social network buttons and no cross-site tracking. The list below is exhaustive.
List verified on 6 August 2026 in a private browsing window, before any interaction with the consent banner.
These cookies are strictly necessary for the service you requested or for the security of the platform. Article 82 of French Act No. 78-17 exempts them from prior consent; they serve no other purpose.
| Cookie | Issued by | Purpose | Lifetime |
|---|---|---|---|
| _odd_score_session | OddScore | Keeps your session alive and protects forms against request forgery. Without it, signing in does not work. | 30 days |
| locale | OddScore | Remembers the language you selected, so we can serve it again on your next visit. | 12 months |
| cf_clearance | Cloudflare | Certifies that your browser passed the anti-bot check of our web application firewall, and protects the platform against automated attacks. | 12 months |
Until you answer, neither exists. If you decline, only "cc_cookie" is set, to remember that refusal and stop asking; "first_touch" is written only if you accept.
| Cookie | Issued by | Purpose | Lifetime |
|---|---|---|---|
| cc_cookie | OddScore | Stores your decision to accept or decline, so we do not ask again on every visit. | 6 months |
| first_touch | OddScore | Remembers the landing page and the source you arrived from, so we can measure how well our acquisition channels perform. | 12 months |
OddScore traffic is measured with Umami, open-source software we host ourselves on our own domain. No traffic data is passed to an advertising network or any other third party.
Umami sets no cookie and writes nothing to your browser storage. Each page view sends the page address, the referring page, the title, the screen resolution and the browser language. Some actions add a named event on top — clicking a navigation link, adding a favourite, submitting a search — sometimes carrying the reference of the match or market concerned. None of these payloads contains an identifier relating to you.
These measurements are used solely to produce aggregated statistics about platform usage. They are not combined with any other processing, allow no tracking across other websites and are never sold. On that basis they fall under the consent exemption the French data protection authority allows for audience measurement.
Traffic data is kept for a maximum of 13 months, then deleted.
The login page loads Cloudflare Turnstile, an anti-bot check with no visual puzzle. It prevents automated sending of login links to email addresses that are not yours.
Turnstile sets no cookie. It does, however, send Cloudflare your IP address and technical signals from your browser for the duration of the check. This verification is indispensable to the service you requested — signing in — and falls under the same exemption as the strictly necessary cookies.
OddScore may send different types of communications:
Marketing communications are optional.
Marketing consent is never pre-checked and can be withdrawn at any time from user settings.
Each category of data is kept for a defined period, then deleted or irreversibly anonymised.
| Data | Retention period |
|---|---|
| Account (email address, display name, preferences, favourites and alerts) | As long as the account is active. After account deletion: 90 days (including the restoration window), then irreversible anonymisation. Billing data is an exception (see its own row). |
| Sign-in session | 30 days after your last activity. |
| In-app notifications | 30 days. |
| Proof of consent (date, version accepted, IP address and browser at the time of consent) | As long as the account is active. The IP address, browser and payment reference are erased when the account is anonymised, 90 days after deletion; only a record with no identity remains (type and version accepted, dates). |
| Devices registered for push notifications | As long as the account is active. Deleted when the account is anonymised, 90 days after deletion. |
| Withdrawal request (first name, last name, email, subscription concerned) | Until our team processes the request, 30 days at most, then deleted, even if your account is closed in the meantime. |
| Billing and payment data (Stripe) | 10 years from issue, under the legal obligation to keep accounting records. |
| Technical logs (IP address, requests, application errors) | 30 days. |
| Error reports (Sentry) | 90 days. |
| Audience measurement (Umami) | 13 months. |
Data may be kept beyond these periods where the law requires it, or for the establishment, exercise or defence of legal claims.
Account deletion can be performed directly from user settings.
This deletion is irreversible. After 90 days, the data that identifies you is anonymised; the retention period for each category of data is detailed above.
In accordance with applicable regulations, you have in particular the following rights:
You also have the right to lodge a complaint with the competent supervisory authority (the CNIL in France): www.cnil.fr
