Privacy
Bifröst runs your agents on your Mac, and your code and conversations stay there. This page says what does leave your Mac, who handles it and how to remove it.
Code, sessions, conversations, artifacts, agent sign-ins and API keys.
Everything between your phone and your Mac. Our relay can't read it.
Your email, your subscription status and a short record of your Mac.
What stays on your Mac
Your sessions, conversations, history, code and artifacts are stored on your Mac. Bifröst doesn't send them to us.
Your agents sign in to Claude Code and Codex with your own accounts. Bifröst doesn't read or keep those sign-ins or your API keys. Your agents talk to their providers, such as Anthropic and OpenAI, under those providers' terms.
Your account
You create an account on this site with an email and a password. It signs you in to Bifröst on your Mac and here. Your phone has no account and never signs in.
Your Mac
So your phone can find your Mac, we keep a random ID for it, the name macOS gives it, how many phones are connected and when it was last online. We don't collect your Mac's hardware ID.
Your phone
Your phone connects by scanning a code on your Mac. It tells your Mac its name and model. The key it uses to reach your Mac stays in the iPhone keychain.
Messages, approvals and commands between your phone and your Mac are end-to-end encrypted with keys exchanged through that code. Our relay sees which session a message belongs to and its order, never what it says. It forgets a disconnected phone after 30 days.
Notifications
When an agent needs you, a notification goes to your phone through Apple Push Notification service. The token that addresses your phone is kept on your Mac, not on our servers. Notifications never include code or full commands.
Payments
Paddle sells the subscription as merchant of record and handles payment and tax. We get your subscription status from Paddle, not your card details.
Logs
Bifröst keeps its logs on your Mac. They reach us only if you export them and send them yourself.
Services we use
Supabase stores your account, subscription and Mac record. Paddle handles payments. Amazon Web Services runs the relay. Apple delivers notifications.
Removing your data
Disconnect a phone from Settings › Devices on your Mac or from Settings on the phone, and both sides forget it. To delete your account and what we keep about it, email support@justcode.kr.
Changes and questions
When this page changes, the date at the top changes with it. Questions go to support@justcode.kr.
