Cookie Policy
Last updated: July 31, 2026
This policy lists the cookies and browser storage this website uses. We use no advertising cookies, no third-party analytics, and no cross-site tracking, so there is no consent banner to dismiss. Everything below is strictly necessary or a preference you set yourself.
Age acknowledgement
When you confirm you are 18 or older, that acknowledgement is stored in your browser (local storage, key "age_ack") so the notice is not shown again on every page. It records only that the confirmation happened. It is not sent to our servers and it is not age verification. Real 18+ verification happens inside the product at sign-up.
Theme preference
If you use the light/dark toggle, your choice is stored in your browser (local storage, key "theme") so the site renders the way you left it. Until you choose, the site follows your operating system setting and stores nothing.
Referral attribution
If you arrive through a referral link, the invite code from that link is stored in a first-party cookie (name "ref") for 30 days so the person who invited you is credited when you sign up. It holds a public, shareable invite code and nothing else: no identifier for you, no browsing history.
Controlling this
Clearing your browser storage for this site removes all of it. The only consequence is that you will see the 18+ notice again, the site will return to following your system theme, and a pending referral credit may be lost.
The product app
The signed-in product at app.4fantasia.com additionally uses a strictly necessary session cookie to keep you logged in. That is covered by the Privacy Policy.
