Cookie notice
The small files this site stores in your browser, and the choices you have. Last updated 21 October 2026.
How we use cookies
Cookies are small text files a website stores in your browser. We use as few as possible.
Essential cookies make the site work: they keep your safari list between pages, protect forms from forgery and remember your cookie choice. They don’t need your consent and can’t be switched off here.
Analytics cookies (Google Analytics) help us see which pages are useful. They are set only after you choose “Allow analytics”, and are not used for advertising.
Cookies on this site
This list follows the site’s settings, so it is always current.
| Cookie | Type | What it does | Lasts |
|---|---|---|---|
gvs_session | Essential | Keeps your safari list and protects forms from forgery. | Until you close the browser |
gvs_consent | Essential | Remembers your cookie choice so we don’t ask on every page. | 12 months |
Changing your choice
Choose “Cookie settings” at the bottom of any page to allow or refuse analytics. Refusing removes the analytics cookies straight away. You can also delete cookies in your browser’s settings; the site still works, but your safari list will be emptied.
