Privacy Policy

This policy covers the CestusAI marketing website. It is deliberately short, because the site does deliberately little. We do not run a data broker, and we do not sell anything about you.

What we collect

If you join the waitlist, we collect the email address you give us, and the time you gave it. That is the only personal information we ask for. We use privacy-respecting analytics that do not build an advertising profile of you.

Why we collect it

Your email is used for one purpose: to tell you when your access cohort opens, and the occasional note when there is genuinely something worth reading. No drip campaign, no third-party marketing.

Where it lives

Waitlist addresses are stored with our email provider under EU data residency. We do not share the list with third parties beyond the infrastructure needed to send you that email.

Your choices

You can unsubscribe from any email in one click. You can ask us to delete your address entirely, and we will, promptly. Write to team@getcestusai.com.

Changes

If this policy changes, the date above changes with it. We will not quietly start collecting more than we describe here.
