Proton Mail is a privacy-focused email service that provides secure, encrypted communication. If you’re using FunOS and want to manage your email from a dedicated desktop application, you’re in luck — Proton Mail offers a native Linux app that integrates smoothly into the system. In this guide, we’ll walk you through the process of installing, launching, and uninstalling the Proton Mail app on FunOS, step by step.

What is Proton Mail?

Proton Mail is a secure email service developed by Proton AG, a company based in Switzerland known for its strong stance on privacy and open-source values. All emails sent and received via Proton Mail are protected with end-to-end encryption, ensuring that only you and your recipient can read them — not even Proton itself.

In addition to its encryption features, Proton Mail offers:

• Zero-access encryption and strict Swiss privacy laws
• Open-source applications and transparency
• Anonymous account registration
• Integration with the Proton ecosystem, including Proton Drive, VPN, and Calendar

The Proton Mail desktop app allows users to access their inbox directly from their system without relying on a web browser, bringing convenience and a native feel to the email experience.
