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.
