Cookie Policy

Last updated: April 2026

What are cookies?

Cookies are small text files stored on your device by your browser. They allow websites to remember information about your visit. iograf uses a minimal number of cookies, all of which are strictly necessary for the application to function.

Cookies we use

iograf uses only essential cookies. We do not use advertising cookies, tracking cookies, or third-party analytics cookies.

localStorage

In addition to cookies, iograf uses browser localStorage (which is not a cookie but functions similarly) to store:

Key Purpose Duration

No tracking or advertising

iograf does not use Google Analytics, Facebook Pixel, or any other third-party tracking service. We do not share any data from cookies or localStorage with advertisers or analytics providers.

How to control cookies

You can control and delete cookies through your browser settings. Note that deleting the authentication cookie (sb-[ref]-auth-token) will sign you out of iograf. You can clear localStorage through your browser's developer tools or by deleting your account via the app settings.
