Cookies and browser storage

What DICOS puts in your browser, why it is there, and what is not there.

1.The short version

DICOS uses cookies for one thing: keeping you signed in. It also keeps a small amount of information in your browser’s local storage, on your own device, so the app can remember where you were.

No advertising or analytics tracker was found anywhere in the current DICOS codebase. There is no analytics dependency in the project, and nothing here follows you to other websites.

2.Essential cookies

Signing in sets authentication cookies. They are what allow the service to know the request for your project is coming from you. Without them you could not stay signed in, so they are essential to the service rather than optional.

These cookies are set by Supabase, the authentication and database service DICOS uses. They are described in the Privacy Policy.

3.Browser local storage

Local storage is not a cookie. It stays on your device, is not sent with every request, and DICOS does not read it from its servers. These are the only keys DICOS writes:

Local storage keys used by DICOS and their purpose
Key	What it is for
authEmail	Remembers the email address you last signed in with, so you do not have to retype it.
lastKnownEmail	The same address, kept so the app can recognise you between visits in the browser.
businessName	The business name for the project you are working on, so the interface can show it.
savedConversations	A local reference to your projects, so the app can find your work quickly.

None of it is used for advertising or profiling. You can clear it at any time through your browser settings, which will sign you out and make the app forget your last-used details.

4.Controlling cookies

Your browser can block or delete cookies. If you block the authentication cookies DICOS will not be able to sign you in, and the product will not work — they are not optional in the way a tracking cookie would be. If you want to know exactly what is set for your account, ask us at DICOS.TECH@proton.me.

5.If this changes

This page describes the software as it is today. If DICOS ever adds analytics, advertising, session recording or any other tracking, this page must be updated before that code ships, and consent requirements must be reconsidered at the same time.
