Cookie Policy
We use a small number of cookies, each with a specific purpose. Last updated April 17, 2026.
Session cookie
After you sign in, the server sets an httpOnly cookie named
op_sid that keeps you authenticated. This is essential to the
functioning of the site and cannot be disabled.
Preference cookies
If you toggle interface preferences (for example, notification settings), we may store the choice in a cookie so the site remembers you across sessions. These are first-party and expire after one year.
Analytics
We use aggregate analytics to understand which lessons are working. These are not linked to your individual account, do not follow you around the web, and are configured with IP truncation.
Your choices
You can clear cookies in your browser settings at any time. Clearing the session cookie will sign you out. Questions about cookies: privacy@omicpathways.org.
