Audience measurement (Google Analytics 4)
With your consent, we load Google Analytics 4 to understand how the site is used: most-visited pages, most-tried cipher methods, traffic sources. The data is aggregated and is never used for advertising targeting.
- Operator: Google Ireland Limited — Gordon House, Barrow Street, Dublin 4, Ireland.
- Cookies set:
_ga(anonymous unique identifier),_ga_<CONTAINER_ID>(GA4 session state). - Retention: 13 months maximum.
- Anonymisation:
anonymize_ipis enabled on the GA side — the last octet of the IP address is truncated before any processing. - Without consent: no Google script is loaded, no
cookie is set, no network request is sent to
googletagmanager.com.
For more on how Google processes the data, see Google's Privacy Policy.
No third-party cookies, no advertising tracker
The site does not load Facebook Pixel, TikTok Pixel, LinkedIn Insight, any ad network, or any fingerprinting tool. The list above is exhaustive — should it change, this page will be updated before deployment.
Manage your consent
- Initial banner: on your first visit, a banner at the bottom of the screen asks you to accept or reject. No measurement script is loaded until you respond.
- Change your choice: use the “Manage cookies” button in the footer. The banner reappears and your decision is updated immediately.
- Browser-level: you can also block or delete cookies via your browser settings (Firefox, Chrome, Safari, etc.).
