Privacy Policy
Last updated: February 2026
Mbox Viewer ("the App") is developed by Color Vivo Internet, S.L. This privacy policy explains how we handle your data.
Local processing
Mbox Viewer processes all email files entirely on your local machine. No email content, metadata, or attachments are transmitted to any server. Your files never leave your Mac.
Index files
The App creates small binary index files alongside your MBOX files for fast access. These index files are stored locally on your machine and are never transmitted anywhere.
License validation
When you activate a Pro license, the App sends only the license key and a device identifier to the Lemon Squeezy API for validation. No email content or personal data is transmitted during this process.
Analytics and tracking
Mbox Viewer does not include any analytics, telemetry, or tracking. We do not collect usage data, crash reports, or any other information about how you use the App.
Newsletter subscription
If you subscribe to our early access list, we store only your email address and the language you signed up in. Your email will be used exclusively for communications related to Mbox Viewer and other applications and services by Color Vivo Internet, S.L. We will never share your email with third parties.
Website
This website does not use cookies or third-party tracking scripts. No personal data is collected during your visit.
