You can read every page on Fullduplex (fullduplex.ai) without an account. This page covers what we collect if you create one or sign in, how we use it, and how to have it removed.
What we collect when you sign in
You sign in with your Google account or with a one-time link we email you. With Google, Google shares your email address, your name and a link to your profile picture with us, and we never see your Google password. With the email link, we only have your email address. Supabase, the service that runs our authentication and database, handles the sign-in.
What we store
Your account details (above), the entries you save (which models, datasets and benchmarks, and when you saved each one), and your answer to "What brings you here?" if you give one.
How we use it
We use it to sign you in, to show your saved list on any device, and to decide what to cover. We do not sell it, show you ads, or share it with anyone except the services that run the site: Supabase for sign-in and data, Resend for sending email, and Vercel for hosting.
The Weekly report is your choice
Creating an account does not subscribe you to the Weekly report. You get it only if you tick the box when you sign up, or turn it on in the account menu. You can turn it off there, and every email has an unsubscribe link.
On your device
Your browser keeps your sign-in session in local storage. The site also remembers whether you collapsed the side menu, and when it last offered you an account, so it does not ask again for 30 days. Signing out removes the session.
Analytics
We use Vercel Web Analytics and Speed Insights to count page views, count how often the sign-up panel is shown, closed and completed, and measure page speed. Neither uses cookies.
Removing your account
Email hi@fullduplex.ai from the address you signed in with, and we will delete your account, your saved list and your answers.
Changes
If this page changes, the date at the top changes with it.
