Privacy Policy

Last updated November 10, 2026

Katie is a voice assistant for your Mac, with this website for signing up, approving drafts and following tasks. This page says what Katie keeps, why, and what you can do about it.

Your account

You sign in with an email address and password, or with Google. Sign-in is handled by our authentication provider, Supabase: Katie never sees your password. Katie keeps your email address and your place in the beta (whether you're admitted or waiting, and your position in line), and sends you a few account emails: one when you join the waitlist and one when you're let in.

Signing in with Google shares your name and email address with Katie. It does not give Katie access to Gmail.

What you ask Katie to do

Katie keeps your requests (what you asked for), the drafts it writes for you to approve, and the results of your tasks, so you can see them in the Mac app and on this website. Contact names, phone numbers, requests and messages are stored encrypted. They never appear in notifications, alert emails or logs.

Research uses public web pages only. Katie never signs in to a website for you, and never books, buys or pays for anything.

Gmail

If you connect Gmail, Katie asks Google for permission to send email only. It never reads, lists or searches your mail. It sends an email only after you approve that exact draft, and only once. Katie keeps the access Google gives it until you disconnect, which you can do at any time; see How Katie uses Gmail.

Katie's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.

Katie writes WhatsApp messages for you to approve. Approving opens WhatsApp with the message filled in, and you press send there. Katie never sends WhatsApp messages itself and doesn't connect to your WhatsApp account.

What this website stores in your browser

Your sign-in session, in your browser's local storage (under a key starting sb-), so you stay signed in. While a sign-in is under way it also holds a one-time code used to finish it. Signing out removes them.
One small flag in session storage, so Buddy says hello only once per visit.

The website sets no cookies and uses no analytics, trackers, advertising pixels or session recording.

Who else handles your data

Supabase runs sign-in. Google handles Gmail if you connect it, and Google sign-in if you use it. Katie doesn't sell your data.

Deleting your data

Disconnect Gmail at any time in the Mac app, on the Connected accounts page, or in your Google Account. To delete your Katie account and its data, contact us.

Changes

If this policy changes, we'll update this page and the date at the top.
