Privacy Policy

Mbox Viewer (“the App”) is developed by Color Vivo Internet, S.L. This policy explains how we handle your data in the App and on this website.

Local processing

Mbox Viewer processes all email files entirely on your machine. No content, metadata or attachments are transmitted to any server. Your files never leave your Mac.

Index files

The App creates small binary index files next to your MBOX files for fast access. They are stored locally and never transmitted anywhere.

Purchases

Upgrading to Pro is an in-app purchase through the Mac App Store. Apple handles payment; we never receive or store your payment details. We run no license-validation server.

Analytics and tracking

Mbox Viewer includes no analytics, telemetry or tracking. We collect no usage data or crash reports.

Contact form

If you write to us from the support page, we receive your name, email and message solely to reply. Delivery is handled via Cloudflare. We do not use this data for marketing or share it with third parties.

Website & cookies

This website uses Google Analytics 4 to measure traffic. By default it runs in cookieless mode (Google Consent Mode): analytics cookies are only set if you accept them in the cookie banner, and you can reject them — the site works the same. Your theme (light/dark) preference is also stored locally in your browser.
