First-party only — a session id and where you arrived from, so we can tell which pages are worth writing more of. No advertising, no third-party trackers, nothing that follows you off this site.
A person reads every message. Refund requests need one line and no explanation — say which purchase and we take care of it.
Often faster than the form, and it works if you would rather not fill anything in.
Within two business days, usually the same day. If you have not heard back in three, something went wrong — send it again and say so.
If something on this site is wrong — a tool detail, a price, a claim in a lesson — telling us is genuinely useful. We fix it and note that it changed.
