Cookies
We use one cookie, and it is there only to keep you signed in. We do not track you around the web, so there is no banner to click away.

The one cookie
When you sign in, we set a small cookie called zv_session. It holds a random code that tells our server it is you. It is only sent to our own site, it cannot be read by scripts on the page, and it lasts for up to 14 days or until you sign out. Without it you would have to sign in again on every page, so it counts as strictly necessary and does not need your consent.
What we do not use
- no advertising cookies;
- no analytics or tracking cookies;
- no social media buttons or embedded videos that set their own cookies.
If this ever changes, we will update this page and ask you first where the law requires it.
At checkout
The card fields on the checkout page are supplied by our payment provider. They may set their own cookies or similar technology to prevent fraud and to take your payment safely. Nothing is set until you reach that page.
