Privacy Policy

Last updated: March 2026

Overview

Zowl is a privacy-first desktop application. It runs entirely on your machine. We collect the absolute minimum data needed to validate your license — and nothing else.

Data We Collect

License activation data

When you activate a Pro license, the following is used for validation:

  • Your license key
  • A machine identifier
  • The email associated with your purchase

This data is stored locally in macOS Keychain and validated via the Lemon Squeezy API.

Purchase information

Your email address and transaction details are handled and stored by Lemon Squeezy, our payment processor. Zowl never sees or stores your credit card information.

That's it.

No analytics. No telemetry. No usage tracking. No crash reports. No cookies.

Data We Do NOT Collect

  • Source code or file contents — your code never leaves your machine through Zowl
  • API keys — passed directly to local CLI processes, never transmitted to any Zowl server
  • Usage patterns — no feature usage, session data, or behavioral tracking
  • Personal information — beyond what Lemon Squeezy provides at purchase, we know nothing about you

Local Storage

All app data — projects, pipelines, tasks, logs, and PRDs — is stored locally on your machine in ~/Library/Application Support/Zowl/. Nothing is synced to any cloud service.

Third-Party Services

Lemon Squeezy

Processes payments and license validation. See their privacy policy.

AI CLI tools (Claude, Codex, etc.)

When you run a pipeline, your configured CLI tools make API calls using your own API keys. These calls go directly from your machine to the AI provider. Zowl does not intercept, log, or store any of this traffic.

Data Retention

All data is local. Uninstalling Zowl and deleting ~/Library/Application Support/Zowl/ removes everything. There is nothing on our end to delete because we never had it.

Children's Privacy

Zowl is not directed at children under 13. We do not knowingly collect data from children.

Changes to This Policy

We may update this policy from time to time. Changes will be posted at zowl.app/privacy.
