Get in touch
One person, one inbox. No contact form, no ticket queue, no autoresponder.
Everything goes to one address, and it reaches Yuvaraj directly:
A specific subject line and a link to the page you are writing about will always get a faster, better answer than a general one.
What to write about
- A mistake in a lesson. The most useful email there is. Include the lesson URL and what is wrong; corrections take priority over new features.
- Deleting your account and data. Write from the address you signed in with and say so — see the privacy policy for exactly what gets removed.
- A security problem. Report it rather than exploiting it, and it will be taken seriously.
- Permission to reuse content. The content is all rights reserved; ask, and say what you want to do with it. See the terms of use.
- A question about the material, or a topic request. Both are welcome. For a question you want answered immediately, the AI tutor is faster — with the caveat that it can be wrong.
What to expect
This is a side project run by one person, not a support desk. Every email is read. Replies are best-effort and can take a while, especially for anything that needs a change to the site. Corrections and data-deletion requests jump the queue.
There is no phone number, no live chat and no postal address to publish — the email address above is the only channel.
