Curio uses only what it needs to work. There are no analytics, advertising or tracking cookies, so there is nothing to consent to and no banner. If that ever changes, you will be asked first, and this page will list them.
Cookies
| Name | What it does | How long |
|---|---|---|
curio-session |
Keeps you signed in after Steam sign-in and ties your requests together. Not readable by scripts. | up to 30 days |
XSRF-TOKEN |
Proves a form or action came from Curio itself, not from another site. | up to 30 days |
locale |
Remembers the language you chose. | 1 year |
locale_persist |
Keeps that choice across the trip to Steam and back when you sign in. | 10 minutes |

These are strictly necessary: the site cannot sign you in, protect your actions or remember your language without them.
Stored in your browser
curio:recent-items— the last items you opened from search, so they are at hand next time. It stays on your device; we never receive it.curio:locale-scroll— your place on the page while the language switches; gone when the tab closes.
Other sites
Item and hero images load from Steam's image servers, which see your IP address as any website you load an image from does. They set no cookies through Curio. Links to Steam open Steam itself, under Steam's own cookie policy.
Clearing them
You can delete cookies and site data in your browser at any time. You will be signed out, and the language and currency return to their defaults.
