Optional website analytics

Only with your consent, we use Google Analytics, provided by Google Ireland Limited, to understand visits to this website. Analytics processes a browser identifier, visits and basic technical information about your browser and device. We do not send names, e-mail addresses, user IDs, URL queries or referring URLs, and do not use advertising personalisation.

The Google tag is not loaded before you allow analytics. Refusing does not limit access to the website. You can withdraw consent at any time through Cookie settings in the footer. Withdrawal stops new collection in this browser; it does not recall information already sent.

Browser storage and retention

Your consent choice is kept in first-party browser storage for up to 180 days, along with a date that fixes the analytics cookie expiry. A necessary opt-out cookie remembers rejection for up to 180 days, including when your browser cannot update its stored preference. This storage is not used for advertising.

After consent, the analytics cookies cisystems_analytics_ga and cisystems_analytics_ga_TBT9HZ9MZ3 use a fixed lifetime of up to 60 days. We configure user and event data retention in Analytics to two months without extending it for each new activity. Google's aggregated reporting has separate retention rules.

Google processing and your choices

Google may process analytics data on infrastructure outside the European Economic Area under its applicable processing and transfer arrangements. Read how Google uses information from sites that use its services.

You may contact us about access, correction, erasure, restriction or objection where applicable, or complain to your data protection authority. Withdrawing consent does not affect the lawfulness of earlier processing.

Technical operation and contacting us

Our server processes connection information to deliver and secure the website, independently of optional analytics. Links to e-mail and telephone open your own application; no contact form or message is sent from this site.
