Essential
The website doesn't work without them, so they don't require consent. We only store your choice from the cookie banner, so the website doesn't ask you on every visit (and, on our team's devices, a marker that they should not be measured). After 12 months (6 months if you rejected cookies) it asks again.
| Name | Purpose | Storage |

| effistream_cookie_consent | Remembers your choice in the cookie banner | Browser local storage, 12 months (6 months after rejecting) |
| effistream_internal | Excludes our team's devices from traffic statistics; set only via an internal link | Cookie, 12 months |
Analytics
They help us understand how people use the website so we can improve it. We use Google Analytics 4 only if measurement is enabled, and start it only after you allow analytics in the cookie banner. Google Analytics advertising features are switched off and we do not use the data to target ads. If you withdraw consent, measurement stops and we delete its cookies.

Server statistics without cookies
Basic counting of full page loads happens on the server, without cookies, local storage or a tracking script in your browser. It is separate from Google Analytics and from your analytics cookie choice. With a Do Not Track or Global Privacy Control signal, only the page load is added to the daily total, without creating a visitor identifier. Details are in our privacy policy.
Marketing
The website currently uses no marketing or advertising cookies (such as ad pixels). If we add them in the future, we will list them here and run them only with your explicit consent.
How to change your choice
You can change your choice at any time with the Cookie settings link in the website footer. You can also block or delete cookies and website data in your browser settings.
How we process personal data is described in our privacy policy.
