What we collect, and what we don't.

The short version

We collect your email when you subscribe. We use it to send you the weekly edition. We don't sell it. We don't share it. You can unsubscribe anytime from the footer of any email.

Email delivery

The newsletter is sent through Resend. They process delivery, open rates, and click data. Their privacy policy applies to that processing.

Site analytics

We use PostHog (cookieless, EU-hosted) to count pageviews and referrers. It does not use cookies and does not identify you personally.

UTM tracking

Subscribe links from our X account, YouTube descriptions, and email footer carry UTM parameters. They tell us which channel a subscriber came from. They do not identify you personally.

Your data, your rights

You can unsubscribe, request a data export, or request a deletion at any time. Email hello@populationcurve.org and we'll handle it within 30 days.
