Short version, in plain language, because a privacy page nobody can read isn't a privacy page.
What's collected. If you start the seven days: your email address and which of the three tracks you picked. Nothing else, and no name is asked for. Separately, anonymous page analytics run through PostHog — pages viewed and links clicked, with no cookies, no session recording and no attempt to work out who you are.
What it's used for. Sending the seven emails, and seeing which pages are worth keeping.
What it is never used for. Selling, sharing or renting to anyone. Changing what anything costs. There is no advertising here and no data goes to advertisers.
A copy, or deletion. Email hello@hansonbarry.me and say which you want. No form, no verification loop. Deletion is immediate and stopping the emails is immediate.
