# Cookie policy

The cookies and similar technologies used on the Chersus website: one strictly necessary session cookie, no analytics, no advertising.

Last updated 2026-09-03

Chersus sets no analytics, advertising, or social-media cookies, and no consent banner is needed: every cookie we set is strictly necessary for a service you asked for. This policy lists them all.

## What cookies are

Cookies are small text files that a site stores in your browser. They can hold a session identifier or a preference so that a site works as you expect when you navigate or return.

## Cookies we use

We use only the two strictly necessary cookies listed below. The marketing site itself sets no cookies at all; the cookies appear when you sign in to the dashboard. We use no tracking pixels, no fingerprinting, and no local storage for tracking.

## Strictly necessary cookies

| Cookie | Purpose | Lifetime |
| --- | --- | --- |
| `better-auth.session_token` | Your dashboard session. An httpOnly, signed token that identifies you to the API. | Until it expires or you sign out |
| `qj_auth_marker` | A readable hint that lets the static homepage show “Dashboard” instead of “Log in” without a network request. It contains no personal data and is verified server-side before it grants anything. | Until you sign out or close your browser |

Without the session cookie the dashboard cannot work. Blocking it disables signing in. Everything else on the Chersus website works without any cookie.

## How to manage cookies

You can delete and block cookies in your browser settings at any time. Signing out removes your session. If you block the session cookie, you can still read every page of the site but you cannot sign in.

## Changes to this policy

We publish every change on this page with a new last-updated date. If a new cookie were ever strictly necessary, we would list it here before it is set.
