Cookie policy
Version: cookies-2026-10-07.1 · 7 October 2026
Technical draft pending legal and privacy review before production.
TradeArena is designed to operate without advertising or behavioural tracking.
Necessary first-party cookies
__Host-tradearena_login holds the encrypted Auth0 transaction for up to 10 minutes; __Host-tradearena_session holds the encrypted session for up to 30 days; and tradearena_locale remembers language for 365 days. In production they are host-only, HttpOnly, Secure, SameSite=Lax and Path=/. Sign-in, accounts or language preference cannot work without them.
External providers
While the site remains closed, Vercel Authentication uses an access cookie and _vercel_sso_nonce for one hour; this layer will disappear from the public domain when production opens. Auth0, Google and Stripe may set their own cookies on their domains when a person signs in, completes a payment or opens the billing portal.
No advertising analytics
The planned configuration does not install advertising, email-open or click-tracking cookies. If this changes, this policy will be updated and legally required consent collected before activation.
Control
You can block or delete cookies in your browser, but blocking necessary cookies prevents sign-in. The technical inventory will be checked again before opening and any non-essential cookie will stay disabled until the required consent control is in place.
