Cookie Policy
Cookie Policy for Bulin 47 AI
Effective 11 October 2026
First-purchase offer cookie
The HttpOnly bb_offer cookie stores a random browser identifier for up to 400 days, subject to browser limits. Its server record preserves your first-visit time across pages and sign-in, and hides the first-purchase offer after a confirmed plan purchase, including after sign-out or a refund. Other open tabs receive a first-party update signal. This is not third-party advertising tracking.
Essential cookies
Bulin 47 AI uses an HttpOnly session cookie to keep you signed in and a short-lived state cookie to protect Google sign-in. These are needed for account access and cannot be used for advertising. Google One Tap uses a short-lived sign-in check and remembers a deliberate sign-out for 24 hours to avoid immediately prompting you again. Google may display its own account-selection prompt on the homepage; the standard Log in link remains available.
Browser storage
Your browser stores generation drafts, selected settings and privacy choices. You can clear local drafts in Settings, or remove all site storage through your browser. Clearing your session cookie signs you out.
Analytics and advertising
No third-party analytics or advertising trackers are enabled. First-party analytics does not set visitor-tracking cookies or store persistent analytics identifiers in your browser. Privacy choices can disable optional analytics, and Do Not Track and Global Privacy Control are respected. A signed HttpOnly bb_internal cookie is used for up to one year on administrator browsers to exclude internal testing even after sign-out. First-party offer cookies and verified business records operate separately.
Other services
Google sign-in and PayPal checkout may use their own cookies on their websites, governed by their respective policies.
OxaPay cryptocurrency checkout takes place on its payment website, where its own cookie and privacy policies apply.
