Contact
One address, read by a person. Most things are answered within two business days, and anything involving money is answered faster than that.
If you have an account, the support form reaches the same place with your details already attached.
What to write about what
- Something is broken, or a lesson looks wrong
- The support form inside your account is the fastest path — it arrives with your account details attached, so nobody has to ask you which email you signed up with.
- Billing, refunds and cancellations
- Write from the address on your account and say which charge you mean. Refunds inside 14 days are issued without discussion.
- Privacy requests
- A copy of your data, a correction, or deletion of your account. We act within 30 days and usually the same week.
- Security
- If you have found a vulnerability, tell us before you tell anyone else and we will work with you on it. Please do not test against other people's accounts.
- Copyright
- Include enough detail to identify the work and where it appears on the site, and we will act promptly.
Before you write
The questions and answers page covers most of what arrives in the inbox — cancelling, refunds, what happens to your code, and what to do when a payment does not show up.
