Cookie Policy
Last updated: Oct 6, 2026
This page lists every cookie and browser storage key F1 Predictions sets, in plain language: what it does, who sets it, and how long it stays on your device. For the fuller picture of what data we collect and why, see our Privacy Policy.
We do not set a first party Stripe cookie: checkout happens on Stripe's own hosted page, not ours. Analytics cookies load only after you accept them in the cookie banner shown on your first visit, in line with Google's Consent Mode v2.
