    Tutanota está a liderar:

    Tutanota is in many ways ahead of Protonmail:
    We are an encryption pioneer: ‘Open soure’ and ‘encrypt everything’ are built into our DNA
    From the beginning we encrypted the entire email (subject, text, attachments) and stored all emails end-to-end encrypted on our servers. In the beginning, Protonmail stored unencrypted emails unencrypted on their servers.
    Protonmail still does not encrypt subject lines.
    Protonmail stores names and email addresses unencrypted in the address book. The Tutanota address book is encrypted entirely – not just parts of the information.
    We offer full-text search on encrypted data since end of 2017. Back then, Protonmail always claimed this was impossible, yet, we built it.
    We don’t promise to open source our clients, we just do it: web client, Android & iOS apps, desktop clients – all are published as open source and developed on GitHub.
    We even offer a Google-free Android app – https://tutanota.com/blog/posts/open-source-email/ – while Protonmail’s app still uses Google Captcha, which enables Google to track users of the Protonmail app.
    We believe security and anonymity go hand-in-hand. That’s why you can use Tutanota anonymously and we would never ask for your phone number to verify your account: https://tutanota.com/blog/posts/anonymous-email/
    Our servers are based in Germany, which has very strong data protection laws: https://tutanota.com/blog/posts/data-protection-germany. Also – unlike Switzerland – Germany has no data retention law for email so once you have deleted an email in your Tutanota mailbox, it’s gone for good: https://en.wikipedia.org/wiki/Data_retention
    The desktop clients are one of the biggest differentiators to Protonmail when it comes to security:
    The Tutanota desktop clients for Linux, Windows and MacOS are open source and handle the entire end-to-end encryption.
    When installing or updating the clients, users can verify that the code published on GitHub is the code that is being run in their local version.
    This is the only way, to make absolutely sure that no man-in-the-middle attack has taken place – and Tutanota is the only secure email service that offers such a solution for free to all users.
    We are a European company and develop everything in Germany for security reasons. We don’t have developers working the USA, and we have never taken venture capital investments from American companies.
