Privacy Policy
Last updated: December 2, 2025
Manaflow (the “Company”) is committed to maintaining robust privacy protections for its users. This Privacy Policy is designed to help you understand how we collect, use and safeguard the information you provide to us.
For purposes of this policy, “Site” refers to the Company’s website at cmux.dev. “Application” refers to the cmux desktop application for macOS. “Service” refers to the Site and Application collectively. The terms “we,” “us,” and “our” refer to the Company. “You” refers to you, as a user of our Service.
By using our Service, you accept this Privacy Policy and our Terms of Service, and you consent to our collection, storage, use and disclosure of your information as described here.
I. Information We Collect
We collect “Non-Personal Information” and “Personal Information.” Non-Personal Information includes information that cannot be used to personally identify you, such as anonymous usage data, platform types, and crash diagnostics. Personal Information includes your email address if you choose to contact us.
1. Information collected via Technology
The Application may collect the following information automatically:
- Crash reports and error diagnostics (via Sentry)
- Operating system version and application version
- Anonymous usage patterns
The Application checks for updates via Sparkle, which may transmit your operating system version and application version to our update server.
2. Information you provide directly
If you contact us via email or our contact page, we collect the information you provide such as your name and email address.
3. Children’s Privacy
The Service is not directed to anyone under the age of 13. We do not knowingly collect information from anyone under 13. If you believe we have collected such information, please contact us at founders@manaflow.com.
II. Third-Party Services
The Application integrates with the following third-party services:
- Sentry — error tracking and crash reporting. May collect error logs, stack traces, device information, and OS version.
- Sparkle — auto-update framework. Transmits application and OS version to check for updates.
- Ghostty / libghostty — terminal rendering engine. Runs entirely locally on your device.
Each of these services has its own privacy policy governing the collection and use of your data.
III. How We Use and Share Information
We do not sell, trade, rent or otherwise share your Personal Information with third parties for marketing purposes. We use crash reports and diagnostics solely to improve the Application. We may share information if we have a good-faith belief that disclosure is necessary to meet legal process or protect against harm.
IV. How We Protect Information
We implement security measures designed to protect your information from unauthorized access, including encryption and secure server software. However, no method of transmission or storage is 100% secure. By using our Service, you acknowledge and agree to assume these risks.

Depending on your location, you may have rights under applicable data protection laws (such as GDPR or CCPA), including:
- Right to access a copy of data we hold about you
- Right to request correction of inaccurate data
- Right to request deletion of your data
- Right to data portability
- Right to restrict or object to processing
To exercise any of these rights, please contact us at founders@manaflow.com.
VI. Links to Other Websites
The Service may provide links to third-party websites. We are not responsible for the privacy practices of those websites. This Privacy Policy applies solely to information collected by us.
