What are cookies?
Cookies are small text files your browser stores when you visit a website. They help a site function, but they are also used to measure visits or track behaviour across sites. Below you'll find exactly which cookies Zeehond.org places and why.
Functional cookies (always active)
These cookies are required for basic site functionality and do not need consent.
| Cookie | Purpose | Duration | Type |
|---|---|---|---|
cookie-consent | Remembers your choice in the cookie banner | 1 year | 1st party |
map-filter | Remembers which filter you chose on the spotting map (species, region) | 30 days | 1st party |
Analytics cookies (Google Analytics 4)
With your consent we use Google Analytics 4 (measurement ID G-9EY8P1F6PE) to measure aggregated visitor numbers, popular pages and broad geographic origin. We have IP anonymisation enabled, do not share data with Google advertising products, and retain GA data for no more than 14 months.
| Cookie | Purpose | Duration | Type |
|---|---|---|---|
_ga | Distinguishes unique visitors (Google Analytics) | 2 years | 3rd party (Google) |
_ga_9EY8P1F6PE | Persists session state for GA4 | 2 years | 3rd party (Google) |
_gid | Distinguishes visitors within a session | 24 hours | 3rd party (Google) |
If you refuse these via the banner, the GA scripts are not loaded and nothing is sent to Google.
External services without cookies
The spotting map loads tile images from OpenStreetMap (tile.openstreetmap.org) and the Leaflet library from unpkg.com. Loading these forwards your IP address to those services, but no cookies are set.
What we do NOT do
- No advertising cookies or remarketing pixels (no AdSense, no DoubleClick).
- No social-media trackers (no Facebook pixel, no LinkedIn Insight Tag).
- No profiling, no resale of data.
Adjusting or withdrawing your consent
You can withdraw consent for GA at any time. Use the "Cookie settings" link at the bottom of every page, or delete the cookie-consent cookie in your browser — the banner will reappear on your next visit. You can also delete cookies through your browser settings at any time.

Changes to the cookies in use will be recorded here with the date of update.
