データのセキュリティは最優先事項です。メッセージはエンドツーエンドで暗号化され、かつゼロアクセスで暗号化されるため、大量監視やデータ漏洩から身を守ることができます。

コントロール

ProtonMailを使用すると、あなたがあなた自身のデータを所有します。他のテクノロジー企業は、あなたのプライバシーを侵害することで数十億ドルを稼いでいますが、私たちは広告を表示せず、あなたのデータを乱用することもしません。

Building an internet that protects privacy, starting with email

Created in Switzerland in 2014 by scientists who met at the European Centre for Nuclear Research (CERN), ProtonMail protects millions of users, including journalists, activists, doctors, lawyers, businesses, and ordinary citizens who want email that is both safer and more private. Because messages are end-to-end encrypted, we cannot read your emails, sell your data to advertisers or compromise the privacy of your communications.
