Cookie Policy

Last updated: June 29, 2026

This policy is based on a direct inspection of the Kenzo AI codebase. The cookies listed here are the only ones currently set by the platform. There are no advertising, tracking, or analytics cookies.

1. What are cookies?

Cookies are small text files that a website stores in your browser. They allow the site to remember information across requests — for example, whether you are signed in.

2. Cookies we use

Kenzo AI currently sets two types of cookies, both strictly functional:

sb-*-auth-token

Essential

Purpose

Maintains your signed-in session. Without this cookie, you would be signed out on every page load.

Set by

Supabase Auth (via @supabase/ssr)

Attributes

HttpOnly · Secure · SameSite=Lax

Expiry

When you sign out or the session expires (managed by Supabase)

kenzo_demo

Essential

Purpose

Tracks whether you are in demo mode (trying the platform preview without creating an account). Prevents demo visitors from being redirected to the login page.

Set by

Kenzo AI (when you click “Try Demo”)

Attributes

HttpOnly · Secure (production) · SameSite=Lax

Expiry

4 hours from when demo mode is activated

3. What we do NOT use

The following are explicitly not used by the Kenzo AI platform:

Advertising or retargeting cookies
Analytics cookies (no Google Analytics, Mixpanel, Segment, etc.)
Social media tracking pixels
Third-party behavioral tracking of any kind
localStorage or sessionStorage for persistent data

4. Third-party cookies

The Kenzo AI application does not embed any third-party scripts that would set their own cookies. The fonts used in the application (Geist Sans and Geist Mono) are downloaded at build time and self-hosted — your browser does not make requests to Google's font servers when loading the platform.

Our hosting provider (Vercel) and database provider (Supabase) may use their own operational cookies as part of their infrastructure. These are outside our direct control.

5. Cookie consent

Because all cookies we set are strictly functional (necessary to operate the service you requested), we do not currently display a cookie consent banner.

6. How to control cookies

You can control and delete cookies through your browser settings. Note that disabling session cookies will prevent you from staying signed in.

You can also sign out of your account to clear authentication cookies, or wait for the demo cookie to expire (4 hours) to end a demo session.
