There is one address for everything: hello@cognosc.com.

What to write to us about

• A question about how it works. Start with how it works, which answers the questions people ask first. If yours isn't there, write to us.
• A student price. Write from your school or university email and we'll send you a student code to use at checkout.
• Something isn’t working, or looks wrong. Tell us what you were doing and what you saw. If a tutor note was wrong, you can report it on the page where you saw it.
• Your data. You can download or delete everything yourself from your account page. For anything else about it, see the privacy page or write to us.
• An idea for a goal, or a correction. If a goal, article or test says something that isn't true, we want to know, with a source if you have one. Ideas for goals are welcome too.

Before you write

It helps to tell us the page you were on, and whether you were signed in. Please don't send a password or card number. We'll never ask for either, and payments are handled by Dodo Payments, not by us.

More about who we are is on the about page.
