A tracker (or “cookie”) is a piece of information stored or read in your browser when you visit a website: a cookie, local storage (localStorage), session storage (sessionStorage) or a script that reads characteristics of your device.
The concierge-os.com website is published by Matthieu de La Selle EI (MAT Agency, ConciergeOS), SIREN 107 023 830, 9 rue du Travail, 74000 Annecy, France. The trackers described below are set by ConciergeOS, except the anti-bot verification, provided by Cloudflare Inc. (United States).
ConciergeOS uses no advertising, social media, cross-site tracking or profiling cookies, and no third-party audience measurement tool. Our fonts and images are served by our own website. Calendly booking opens in a new tab: no Calendly tracker is set on our website.

All these trackers are either strictly necessary for the service you ask for (login, security, conversation, application, display preference), or used for internal audience measurement that meets the exemption conditions set by the CNIL. They therefore do not require your consent (article 82 of the French Data Protection Act). If we ever add a tracker that requires consent, a banner will let you accept or refuse it just as easily.
Our audience measurement counts page views, the referring site and a truncated IP address (never the full address), with no visitor identifier and no cross-referencing with other data. It is used only to produce statistics about our own website, and visits are deleted after 12 months. You can object at any time: your choice is stored in your browser.
You can delete cookies and site data at any time from your browser settings (Chrome: Settings > Privacy and security; Safari: Settings > Privacy > Manage Website Data; Firefox: Settings > Privacy & Security; Edge: Settings > Cookies and site permissions). If you block local storage, logging in to the client area will not work.
Data collected through these trackers is processed in accordance with our privacy policy, which describes your rights and how to exercise them. You can also contact the CNIL (cnil.fr).
This policy is updated whenever a tracker is added or removed. For any question: contact.conciergeos@gmail.com.
