Nothing until you contact me. There are no accounts, no checkout, and no advertising trackers on this site.
I receive your name, your email address and whatever you write. It is used to answer you and nothing else. It is not sold, rented or added to a mailing list you did not ask for.
This site sets one cookie, and only if you accept it: a first-party analytics cookie that counts page visits anonymously. If you decline, no cookie is set and you are counted in aggregate only. You can change your mind at any time using the link in the footer.
This site is hosted by Cloudflare. Aggregate, anonymous request data passes through them as a hosting provider. No other third party receives anything.
Email is kept for as long as the conversation is useful, and then it is deleted. Analytics data is retained for 12 months.
Canadian PIPEDA and, for visitors in Europe, GDPR give you the right to ask what is held about you and to have it deleted. Write to the address in the footer and it will be done.
