Cookies

TC Engine uses a small number of cookies to keep the site secure and to optionally load third‑party embeds.

Essential cookies

These cookies are required for the site to function securely:

• tc_turnstile_ok

  • Purpose: Anti-bot protection for forms and checkout (Cloudflare Turnstile).
  • When set: After you complete the human verification.
  • Duration: Up to ~8 hours.
  • Notes: This cookie is required to protect our inbox and Stripe checkout endpoints from automated abuse.

• tc_admin_session

  • Purpose: Admin authentication session cookie.
  • When set: After a valid admin magic-link sign-in.
  • Duration: Up to 7 days.
  • Notes: This cookie is HttpOnly (not accessible from client-side JavaScript).

• tc_cookie_consent_v1

  • Purpose: Stores your cookie preference (whether optional LinkedIn embeds are enabled).
  • When set: When you accept or reject non-essential cookies.
  • Duration: ~180 days.

Optional cookies / third‑party content

If you enable LinkedIn embeds, we will load LinkedIn iframes on the /logs page.

• LinkedIn may set its own cookies and use its own tracking and analytics mechanisms.
• If you do not enable LinkedIn embeds, we do not load those iframes.

How to change your choice

Today the simplest way to change your choice is:

• Clear the tc_cookie_consent_v1 cookie in your browser for this site, then reload the page to see the cookie banner again.

(We may add an in-page “cookie settings” control later.)
