1. What we use cookies for
#Cookies are small files a site keeps in your browser. Zerqano uses the cookies it needs to keep you signed in and to open your workspace the right way; those are always set. Analytics cookies are set only if you choose “Accept all” in the cookie banner, and you can change that choice at any time. Zerqano also records simple product events on its own servers whatever you choose; the Privacy policy explains them.
Zerqano does not use advertising cookies.
2. Signing in
#Set when you sign in to the app, whatever you chose in the cookie banner: the app cannot keep you signed in without them. Signing out removes the session cookies.

sb-<project>-auth-token | Your sign-in session as kept by Supabase, the sign-in service we use. A long session is split across cookies ending in .0, .1 and so on. | Up to 400 days |
sb-<project>-auth-token-code-verifier | A one-time check value Supabase keeps while you sign in with Google or reset your password, so that only this browser can finish it. It is removed when the sign-in or reset completes. | Until the sign-in or reset completes; up to 400 days if it never does |
user | Your account record from the sign-in service, such as your user ID and email address, used to check your sign-in. Scripts on the page cannot read it. | 7 days |

5. Analytics
#Not set on this site: analytics is not switched on here, whatever you choose in the cookie banner. If it is switched on, this cookie is set only if you choose “Accept all”.
| Name | What it is for | How long it lasts |
|---|---|---|
ph_<project key>_posthog | PostHog product analytics: a random ID for your browser and your current visit, so we can count visits and see which pages are used. After you sign in, analytics events are linked to your account. PostHog keeps a copy in your browser’s storage under the same name. | 365 days |
6. Stored in your browser, not as cookies
#Kept in your browser’s local storage. Unlike cookies, they are not sent with each request. The signed-in app also keeps its own working settings there, such as your text size, workspace layout and table views.
| Name | What it is for | How long it lasts |
|---|---|---|
zerqano_cookie_consent_v1 | Your cookie choice and when you made it. | Until you clear site data |
zerqano_visitor_landed_v1 | Set only if you allowed analytics: the time of your first visit, so a first-visit event is sent once. | Until you clear site data |
__ph_opt_in_out_<project key> | PostHog’s record of your analytics choice, written when you change it after allowing analytics. | Until you clear site data |
chatMessages, chatModel | Set on the sign-in pages and in the app: your assistant conversation on this device, empty until you use it, and the assistant’s setting. | Until you clear site data |
chakra-ui-color-mode, Zerqano-workspace-mode | Set on the sign-in pages and in the app: your display settings. | Until you clear site data |
Zerqano_sw_build_version | Set on the sign-in pages and in the app: the installed version of the app, so it can update itself. | Until you clear site data |
device_id, mcp_client_id, mcp_last_conn_attempt | Set only once you are signed in: random IDs for this browser and the time of the last connection attempt, used for live updates. | Until you clear site data |
7. Security check on forms
#The sign-in, sign-up and demo request forms can show a Cloudflare Turnstile check that tells people apart from automated submissions. It runs in a frame from challenges.cloudflare.com. Cloudflare processes your IP address and browser signals for this check, and acts as an independent controller when it uses those signals to improve its bot detection. Zerqano sets no cookie for it.
8. Changing your choice
#Use Cookie settings in the footer of every page of the public site, or the button below, to open the cookie banner again. In the signed-in app, Cookie settings in your account menu opens this page. Choosing “Reject non-essential” stops analytics on that page and deletes the PostHog cookie. Your choice is kept in this browser only.
Your browser’s settings can also delete this site’s cookies and stored data at any time. That signs you out, and where this site has analytics switched on, the banner asks for your choice again.
