Your email address if you give it to us, and what you bought. Payments are handled by our payment processor — we never see or store your card number.
Send you what you bought, send you the lessons you asked for, and answer you when you write to us. That is the whole list.
We do not sell your address, rent it, trade it, or hand it to a data broker. We do not run advertising on this site and nobody pays us to put a product in front of you.
Every email has a one-click unsubscribe. Ask us to delete your data and we delete it, usually the same day.
