Privacy Policy

Last updated: March 13, 2026

What we collect

Account data: Email address (or Apple ID) and hashed password when you create an account.

Device tokens: iOS push notification tokens, used solely to deliver agent alert push notifications to your device.

Agent notifications: Agent name, message, and severity are forwarded from your Mac to our backend only to deliver push notifications to your iOS device. We do not store notification content after delivery.

What we don't collect

We do not collect your code, terminal output, file contents, browsing history, or any data from your AI agents. The local Unix socket server runs entirely on your machine. Notification content is forwarded transiently and not persisted.

Local data

The Zestful macOS app communicates with agents via a Unix domain socket at /tmp/zestful.sock with a local authentication token stored at ~/.config/zestful/local-token. This data never leaves your machine unless you are logged in and have iOS push notifications enabled.

Third-party services

We use Supabase for authentication and Apple Push Notification service (APNs) for iOS push delivery. Your data is handled according to their respective privacy policies.

Data deletion

You can delete your account at any time from the Settings tab in the app. This removes all associated data from our servers.
