Which cookies we use and how you choose
WikiDetail currently uses only what is needed to make the site work. We measure visitor numbers without cookies and without storing anything on your device. Advertisements are off; if they arrive, your choice determines only whether they are tailored to you, not whether you see them.

- We count how often a product page or business profile is viewed, without a cookie and without storing who looked.
- We measure visitor numbers per page with Vercel Web Analytics, without a cookie, without storage on your device and without linking to your account. We send only the path of the page, never search terms, unsubscribe links or sharing keys. Vercel creates a temporary code per visitor from your IP address and browser, which is discarded after 24 hours.
- Error reports go to Sentry (data centre in the EU), without a cookie, without IP address and without what you entered.
- Payment for Plus takes place on a Stripe page (checkout.stripe.com); Stripe's cookies for payment and fraud prevention apply there (stripe.com/cookies-policy). On wikidetail.com itself Stripe sets nothing.
- The map on a business profile comes from OpenStreetMap and loads as soon as you open the profile; OpenStreetMap receives your IP address when it does. The map sets no cookie on wikidetail.com.
- If you do not choose a country, we derive it from your request on each visit, without a cookie and without storing anything.
Only after consent (not yet active)
These components are currently off. If one is switched on, we first ask for your choice and update this page.
Affiliate measurementOff
Measuring whether a click to a shop leads to a purchase. Ordinary shop links work without it, and the price order does not change because of it. Not yet active.
Advertisements (Google AdSense)Off
Showing and measuring advertisements. Your choice is asked by Google's consent message, a certified consent management platform under the IAB standard (TCF). Your choice does not determine whether you see ads, but which ones: with consent, ads tailored to you, with Google cookies such as __gads, __gpi and __eoi; without consent, limited ads that match only the page, without cookies and without storage on your device. Google stores your choice itself in FCCDCF and FCNEC. Members of WikiDetail Plus see no advertisements. Not yet active.
