Data collected

The site opalecrest.com measures its audience without a cookie and without storing anything in your browser. For each page viewed, it sends the publisher's statistics tool the page address, the site you came from and, where present, the campaign parameters. To count the distinct visitors of a day, a fingerprint is computed from your IP address and your browser with a key renewed every day and then erased: the IP address is not kept, and the same person cannot be recognised from one day to the next, nor from one site to another. These statistics are kept on servers of OVH SAS (2 rue Kellermann, 59100 Roubaix) located in France. The site collects no other data.

Hosting

The site is hosted by Vercel Inc., 340 S Lemon Ave #4133, Walnut, CA 91789, USA. That host may process technical connection data outside the European Union; those transfers are framed by the European Commission's standard contractual clauses.

Consent

Limited to audience statistics, this measurement requires no prior consent. Its data is neither combined with other processing nor passed on to third parties.

Our apps and games

Processing related to an app or a game is described in its own privacy policy, reachable from its own site:

• Korem
• Voyelle
• OpaleCrest Games
