What Are Cookies
Cookies are small text files stored on your device when you visit a website. Some sites also store similar data in your browser's local storage. This page lists everything T21 Compass stores in your browser.
Analytics & Your Choice
We do not use advertising cookies or cross-site trackers. With your consent, we use Google Analytics to measure aggregate, anonymized site usage. Analytics cookies load only after you choose "Accept" in the cookie banner, and not at all if you choose "Reject." Analytics data is never sold and never used to train AI models. Everything else we store is essential to making the platform work.
What We Store
| Name | Type | Purpose | Duration |
|---|---|---|---|
| access_token | Cookie | Authentication — keeps you signed in | 1 hour |
| cookie_consent / consent_timestamp | Local storage | Remembers that you dismissed the cookie notice | 1 year |
| sb-*-auth-token | Local storage | Sign-in session managed by our authentication provider (Supabase) | Until sign-out |
| _ga, _ga_* | Cookie (analytics — optional) | Google Analytics: aggregate, anonymized usage measurement. Set only if you choose Accept | Up to 2 years |
Essential vs. Optional
The access_token cookie and the Supabase session are essential for the platform to function. Without them, you cannot remain signed in or use the AI guides. The only non-essential items are the Google Analytics cookies, which are set solely if you choose "Accept." To opt out, choose "Reject" in the cookie banner — no analytics cookies are set at all.
Managing Cookies
You can control or clear cookies and local storage through your browser settings at any time. Note that clearing essential items will sign you out. To change your analytics choice, clear the cookie_consent item to bring the cookie banner back, then choose again.
