Email support

Support email: [email protected].

Email is our published support channel for order problems, account issues, privacy requests, and promoter questions. Please allow time for investigation, especially when we need to check payment-provider or PDF-generation records.

Information to include

For a purchase issue, include the date, order or transaction reference, lecture URL, selected language, and a brief explanation of what went wrong. If your issue relates to sign-in or referrals, explain the affected page and the error message.

Do not share passwords, one-time invitation links, full card details, government identity documents, secret API keys, or bank credentials by email. We may request account verification through an appropriate method.

Feedback

You can also use the Feedback control on the homepage for general comments and suggestions. For urgent purchase disputes, account access problems, privacy matters, or refund requests, use the support email above so your request can be tracked.
