Cookie policy
Cookies are small files stored on your device. This page says which ones we use and how you choose.
Necessary cookies
These keep you signed in, remember the tab you are using, and protect forms from some cross-site abuse. The app cannot work without them.
Optional cookies
If you choose Accept all, we may store a record of that choice and basic anonymous measurements of public pages (for example, whether the landing page loaded). We do not use optional cookies to advertise to students.
Your choice
On the landing and login screens you can choose Accept all or Necessary only. After you have an account, you also confirm this choice when you agree to Terms, Cookies, and Privacy Policy.
You can change cookie choice later from Settings. Withdrawing optional cookies does not delete your account.
