This Cookie Policy explains what cookies and similar tracking technologies we use on econdiagrams.com, why we use them, and how you can control them. It should be read alongside our Privacy Policy.
What is a cookie?
A cookie is a small text file placed on your device by a website you visit. Cookies are widely used to make websites work, or work more efficiently, and to provide information to the site owner. Similar technologies include localStorage, session storage, pixels, and SDKs — this policy covers all of them.
How we categorise cookies
We group cookies into three categories:
- Necessary — required for the site to work (login, security). Cannot be disabled.
- Analytics — help us understand how visitors use the site so we can improve it.
- Marketing — used by advertising platforms to measure campaigns and (where applicable) show you relevant ads.
Analytics and Marketing cookies only load after you give consent via the cookie banner. You can change your choice at any time using the "Cookie settings" link in the footer.

- Cookie settings — click "Cookie settings" in the footer at any time to change your preferences.
- Your browser — all modern browsers allow you to block or delete cookies. Note that disabling necessary cookies will break login and core functionality.
