If you subscribe to the newsletter

The newsletter runs on our own infrastructure — a Cloudflare Worker with a Cloudflare D1 database, sending through Cloudflare's email service. No third-party newsletter company holds the list. When you subscribe we store:

Subscription is double opt-in: no confirmation click, no email. The emails themselves contain no tracking pixels — we do not know whether you open them or what you click. Every email carries a one-click unsubscribe that works immediately. Unsubscribing stops all email at once; to have your address deleted from the database entirely, email tips@groundtruth.health with the subject “Delete my data” and it will be removed.

Analytics on the site

The site currently uses Google Analytics 4 to count visits in aggregate — which pages are read, roughly where readers come from. That means Google sets identifiers in your browser and processes your IP address under Google's privacy policy. We use the default configuration, look only at aggregate numbers, and run no advertising, remarketing, or audience features. Page fonts are served from Google Fonts, so your browser also requests files from Google's servers when a page loads.

What we never do

Retention

Subscriber records are kept while you are subscribed. If you unsubscribe, the record is marked unsubscribed and kept only so we cannot accidentally email you again; ask and it will be deleted outright. Aggregate analytics follow Google Analytics' standard retention settings.

Questions or deletion requests
