นโยบายคุกกี้

1. About this policy

This policy explains how the official BIOSPHERE-AI website (biosphere-ai.com, the "Site") uses cookies and similar technologies. Read it together with our Privacy Policy.

2. What we use

• Essential cookies: only for the admin console login session (HttpOnly, encrypted in transit). Ordinary visitors browse without any login cookies being set;
• Human verification: the admin login page loads Cloudflare Turnstile, which may set its own functional cookies during verification, used solely to tell humans from bots;
• Browser local storage (localStorage / sessionStorage): stores your language preference, inquiry list and AI-assistant chat draft. This data stays on your own device, is never uploaded, and is removed when you clear site data.

3. What we do not use

• No third-party advertising cookies or tracking pixels;
• No cross-site tracking and no sharing of visit data with ad networks;
• No fingerprinting or other covert tracking techniques.

4. Managing cookies

You can inspect, clear or block cookies and site data in your browser settings. Blocking essential cookies only affects admin login and has no impact on ordinary browsing.

5. Changes

Changes to this policy will be published on this page with an updated effective date.
