Ask us anything about it.
Questions before you start, feedback once you have, or a problem with a payment or a lesson. It reaches a person rather than a ticket queue, and you do not need an account to write.
If you would rather use your own mail client, write to contact@howdoistudy.com.
For anything about your data specifically (a copy of it, or deleting it), the privacy notice says what we hold and how to get it, and an account can export or delete itself from settings without asking us.
