This is not legal advice. We may update this policy as the product evolves.
Data we collect
Waitlist: email address when you join the waitlist.
Contact form: email address, optional name, and message content when you contact us.
Analytics: usage data such as pages viewed, button clicks, device/browser type, and approximate location derived from IP. We use PostHog for this.
Technical data: standard server and security logs from our host (Vercel).
How we use data
To operate the waitlist and send product updates you signed up for.
To respond to contact form messages.

Legitimate interests — responding to enquiries, site security, and aggregated analytics.

We use service providers to run the site. They process data on our instructions:
Resend — waitlist contacts and outbound email.
