Cookies Policy

Last updated: 21 May 2026

1. What are cookies

Cookies are small text files a website stores on your device (computer, phone, tablet) while you browse. They allow the site to recognize your browser on subsequent visits, remember preferences, and measure how the site is used.

GRPC uses cookies in two categories: essential (always on, required for the site to work) and analytics (Google Analytics — loaded only with your explicit consent).

2. Essential cookies

Indispensable for the site to function. They do not collect personal data for marketing. Legal basis: legitimate interest (Art. 6(1)(f) GDPR).

Cookie	Purpose	Duration
`__Host-next-auth.csrf-token`	CSRF protection on the admin login form	Session
`__Secure-next-auth.session-token`	Authenticated GRPC staff session at `/admin`	1 hour
`__Secure-next-auth.callback-url`	Post-login redirect	Session
`grpc_consent_v1`	Local storage (not cookie) of your analytics consent choice	Until cleared

3. Analytics cookies (consent)

Help us understand how visitors use the site, so we can improve the experience. Loaded only after your explicit consent. Legal basis: consent (Art. 6(1)(a) GDPR).

Cookie	Provider	Purpose	Duration
`_ga`	Google Analytics	Distinguishes unique users	2 years
`_ga_SVS6EG8B20`	Google Analytics	GA4 session state	2 years

4. Google Analytics "cookieless" mode

Even when you decline analytics cookies, Google Analytics keeps sending anonymous aggregate pings via the so-called Consent Mode v2— no cookies, no persistent identifiers, no cross-page tracking. These pings produce modeled statistical metrics that comply with GDPR. It is a Google requirement so reports don't end up with massive blind spots when many visitors decline.

5. Managing your preferences

You can review or change your choices any time by clicking "Cookie settings" in the site footer. The banner reopens with your current state pre-selected.

You can also block or clear cookies directly in your browser settings:

Note: blocking essential cookies will prevent the admin area from working. Public browsing (homepage, newsletters, documents) stays available.
