Google Analytics
If you choose website analytics, we use Google Analytics to understand how visitors use our public website. It is not loaded in the authenticated product, onboarding, or OAuth-return pages. Google's privacy policy is available at: https://policies.google.com/privacy
Product Analytics
After accepting the Terms and Privacy Policy during onboarding, authenticated users' product interactions are measured with PostHog. PostHog receives only a pseudonymous account identifier and allowlisted product events. It does not receive health data, form answers, free text, email addresses, or tokens. OAuth callback URLs are never sent as automatic page views.
