Privacy Policy

Last updated: March 13, 2026

Summary

Krust does not collect, store, or transmit any personal data or usage telemetry. Your Kubernetes clusters, configurations, and workflows stay entirely on your machine.

Data We Do Not Collect

• No telemetry — Krust sends zero analytics, crash reports, or usage data
• No tracking — No cookies, fingerprinting, or third-party trackers in the app
• No cluster data — Your Kubernetes API calls go directly from your machine to your clusters. Krust never proxies, intercepts, or stores cluster data on any external server
• No personal data — We do not collect names, emails, IP addresses, or device identifiers through the app

License Activation

When you activate a Krust Pro license, the app communicates with LemonSqueezy (our payment processor) to validate your license key. This exchange includes:

• Your license key
• A device instance name (your Mac's name, used to label the activation)

This data is processed by LemonSqueezy under their privacy policy. No other data is sent.

AI Diagnostic Agent

The AI diagnostic feature sends Kubernetes resource data (pod specs, events, logs) to Anthropic's Claude API for analysis. This data:

• Is sent directly from your machine to Anthropic's API
• Is not stored by Krust on any server
• Is subject to Anthropic's privacy policy

The AI feature is opt-in — it only activates when you explicitly request a diagnosis. No data is sent in the background.

Software Updates

Krust uses Sparkle for update checks. When checking for updates, your Mac contacts our update server to compare version numbers. No personal data is transmitted. You can disable update checks in Settings.

Local Storage

Krust stores the following locally on your machine:

• Application preferences (UserDefaults)
• License credentials (macOS Keychain, encrypted by the OS)
• AI conversation memory (local files only)

This data never leaves your machine unless you explicitly choose to share it.

Website

The krust.io website uses Google Analytics to understand visitor traffic (pages visited, referral sources). No personal data is collected beyond standard analytics. The waitlist signup is processed by Buttondown under their privacy policy.

Changes

We may update this policy as features evolve. Changes will be posted on this page with an updated date.
