Cookies policy

Last updated: 27 May 2026

This is the full list of cookies thesium.tech can set in your browser, and what each one is for. We use the bare minimum — no advertising, no third-party analytics, no cross-site tracking.

Strictly necessary

These are required for the site to function. There is no opt-out — without them you can't sign in or stay signed in.

thesium_session: Issued after you log in. Identifies your authenticated session. HttpOnly, Secure, SameSite=Lax. Expires after 30 days of inactivity.
thesium_csrf: A random token attached to form submissions, used to confirm requests originate from this site. Cleared when you close the tab.

Preferences

Optional. If absent, the site falls back to sensible defaults.

thesium_theme: Remembers whether you've set the site to light or dark. If not set, we follow your operating system preference. Lifetime one year.

What we don't use

No Google Analytics, Meta Pixel, Mixpanel, Segment, Plausible, or other third-party analytics.
No advertising, retargeting, or affiliate cookies.
No third-party scripts that set cookies on our behalf — the only cookies on this site are set by this site.
No cross-site or cross-device tracking.

The Chrome extension

The Thesium extension does not set cookies on the pages it activates on (AXIOM, GMGN, Photon, Basedbot, Terminal). It runs in an isolated content script and uses chrome.storage.local for small UI state such as whether the panel is collapsed or expanded. That state stays in your browser and is never transmitted to us.

Managing cookies

You can clear cookies for thesium.tech from your browser's privacy settings at any time. The session cookie disappears when you sign out, and the rest can be cleared manually. If you remove the session cookie you'll need to log in again.

Do Not Track and Global Privacy Control

We honor the GPC and DNT headers. The cookies above are functional rather than tracking, so they continue to work either way — but any future feature that touches aggregate counters or third-party services will default to off when one of those signals is present.
