Cookie Policy
Last updated: 14 January 2026
This policy explains what cookies are, how Bitflowmatrixfr uses them, and how you can manage your preferences at any time. Our approach: no advertising or analytical cookie is activated before your explicit consent.
1. What is a cookie?
A cookie is a small file placed on your device when you visit a website. Depending on its type, it allows the site to recognise your browser, remember your choices, or measure how you interact with the site.
2. Categories used
We use four cookie categories: (a) strictly necessary — operation and security; (b) functional — language preference; (c) audience measurement — anonymised statistics; (d) advertising and personalisation — campaign measurement via Google Ads. Only category (a) is active by default.
3. Google Consent Mode v2
We implement Google Consent Mode v2. Concretely, as long as you have not accepted, the following signals remain 'denied': ad_storage, ad_user_data, ad_personalization, analytics_storage. Your choices are transmitted to Google services as anonymous signals, without marketing cookies.
4. How to withdraw or change your consent
You can change your preferences at any time via the 'Manage cookies' link located in the footer, or by clearing your browser data — the banner will reappear automatically on your next visit.
5. Cookie lifetime
The cookie storing your decision is kept for a maximum of 13 months, in line with the CNIL guidelines. After that period, we will ask for your consent again.
6. Third-party cookies
When you consent, some cookies are placed by Google Ireland Limited (Google Ads campaign measurement). We do not allow any social network cookies or external advertising tracking beyond these services.
