Zero

What is Zero?

Zero is the first open-source email application designed to prioritize your privacy and security above all else. Unlike traditional email clients that often mine your data or expose you to trackers, Zero ensures that your communications remain confidential and free from prying eyes. Built on a foundation of transparency, its open-source code allows security experts and users alike to verify that there are no hidden backdoors or data collection mechanisms.

Key features include end-to-end encryption for all messages, ensuring that only you and your intended recipient can read the content. Zero also blocks tracking pixels and other invasive technologies that are commonly embedded in emails to monitor your behavior. The app supports multiple email providers, including Gmail, Outlook, and custom domains, making it easy to integrate into your existing workflow without sacrificing privacy.

Benefits extend beyond security; Zero offers a clean, intuitive interface that streamlines email management. Features like smart folders, customizable filters, and a unified inbox help you stay organized. The app is available on both desktop and mobile platforms, with seamless synchronization across devices. Use cases range from journalists and activists who require airtight security to everyday users who simply value their privacy. Technical details include support for PGP encryption, OAuth2 authentication, and a modular architecture that allows for community-driven enhancements. Zero is not just an email app; it's a statement that privacy is a fundamental right. By choosing Zero, you take control of your digital identity and contribute to a more secure internet ecosystem. Whether you're managing sensitive business correspondence or personal messages, Zero provides the peace of mind that your data is yours alone.
