Privacy & analytics

We use PostHog and Google Analytics to understand visits, returning browsers, useful pages, referring websites, campaign performance and actions such as newsletter signups and guide download clicks. Analytics uses cookies and browser storage to recognize a browser across visits, with an expiry of up to 180 days that may renew with activity. We do not enable session recordings or send subscriber email addresses to these analytics reports.

Since October 19, 2026, PostHog also receives page speed measurements (how fast a page loads and responds) and reports of JavaScript errors so we can fix broken pages. Error reports include the error message and the location in our code, not what you typed or the contents of the page.

PostHog processes IP addresses and browser information for approximate location and detection of known bots. Analytics reports do not identify the person using a browser. We respect previously recorded analytics opt-outs, Global Privacy Control and Do Not Track signals. Advertising features, Google Signals and advertising personalization are disabled.

Our analytics events remove URL query strings and fragments, and keep referring URLs at the website origin level. We separately retain selected campaign names such as newsletter source and campaign identifiers. Google and PostHog process analytics data for their respective services. Read how Google uses information from sites that use its services and PostHog’s privacy information.

Links in The Mortal Brief pass through aiformortals.co/r, which records the issue, which link was clicked, the time, the browser type and a hashed, day-scoped version of the IP address, then sends you on. Poll answers from the Brief are stored the same way, with any comment you choose to add. Neither includes your email address.

If you subscribe or request guide extras, we process the email address you submit to deliver the newsletter or requested resources. Newsletter emails include an unsubscribe link.

When you subscribe, we also store how you found us with your email address: the page you signed up on, the first page of that visit, the referring website and any campaign tags. If you answer the optional questions after signing up, we store those answers too. We use this to decide what the newsletter covers.

Analytics tracking began September 22, 2026. It does not provide historical visitor records from before installation.
