Only your email address, when you join the waitlist. We also note which link brought you (for example "landing") so we know what's working. No names, no tracking cookies, no ad pixels.
In our database at Supabase, a hosted database provider. Visitors to the site can add an email but can't read the list.
To email you launch updates, your early-bird pricing, and the GreenlightKit newsletter. That's it.
We never sell, rent or trade your email. We only share it with the service we use to send email, and only so it can deliver our messages.
Every email has an unsubscribe link. You can also email hello@greenlightkit.com any time and we'll remove your address completely.
Write to hello@greenlightkit.com. A real person reads it.
