Attentico uses cookies and similar technologies (local storage, session storage) to make the service work, remember your sign-in, and understand how the site is used. This document explains exactly what's set and how you can manage them.
A cookie is a small text file your browser stores when you visit a website. It helps the site remember your preferences or session next time. Beyond cookies we also use 'localStorage' and 'sessionStorage' — similar storage in your browser, but nothing gets sent back to a server.
Grouped by purpose:
Required for the service to work. Without these, you can't log in or use your account. These are always set when you use Attentico.

Strictly necessary cookies are always active — the service won't work without them. Functional and analytics cookies can be declined via the cookie banner on your first visit, or removed afterwards via your browser settings. In every major browser you'll find this under Privacy & Security → Cookies and site data. Removing the auth cookie means you'll have to log in again.
If we start using new cookies (e.g. for a new partner), we'll update this document and notify you in the app. The 'Last updated' date at the top of this page will change.
