Cookie policy
We only use cookies the site needs to work. No analytics, no advertising, no tracking across other websites — so there's no cookie banner.

The cookies we use
- Sign-in (sb-… , set by Supabase) — keeps you signed in. Lasts until you sign out or the session expires.
- lang — remembers English or 中文. Lasts one year.
- gt_intro — remembers you've already seen the opening screen, so it doesn't show on every page. Deleted when you close your browser.
Managing cookies
You can delete or block cookies in your browser settings. If you block the sign-in cookie you won't be able to stay signed in.
Changes
If we ever add analytics or other optional cookies, we'll ask for your consent first and update this page.
