■ 概要
Keep your conversations private. Proton Mail is encrypted email from Switzerland. Used by millions worldwide, our all-new email app protects your communications and has everything you need to easily manage your inbox.

The Wall Street Journal says:
“Proton Mail offers encrypted email, which makes it virtually impossible for anyone to read it except the sender and the recipient.”

With the all-new Proton Mail app, you can:
? Create a @proton.me or @protonmail.com email address
? Send and receive encrypted emails and attachments with ease
? Switch between multiple Proton Mail accounts
? Easily manage your email with conversations
? Keep your inbox tidy and clean with folders, labels and simple swipe-gestures
? Receive new email notifications
? Send Password-protected Emails to anyone
? Enjoy your inbox in dark mode

Why use Proton Mail?
? Proton Mail is free ? We believe everyone deserves privacy. Upgrade to a paid plan to get more done and support our mission.
? Easy to use ? Our all-new app has been redesigned to make it easier to read, organize, and write your emails.
? Your inbox is yours ? We don’t spy on your communications to show you targeted ads. Your inbox, your rules.
? Rigorous encryption ? Your entire inbox is secured, on all your devices. No one can read your emails but you. Proton is privacy, guaranteed by end-to-end and zero-access encryption.
? Unmatched protection ? We offer strong phishing, spam, and spying/tracking protection for all your communications.

Industry Leading Security Features
Messages are stored on Proton Mail servers using end-to-end encryption at all times and are transmitted securely between Proton servers and user devices. This largely eliminates the risk of message interception.

Zero Access to Your Email Content
Proton Mail's zero access architecture means that your data is encrypted in a way that makes it inaccessible to us. Data is encrypted on the client side using an encryption key that Proton does not have access to. This means we don't have the technical ability to decrypt your messages.

Open-Source Cryptography
Proton Mail's open-source software has been thoroughly vetted by security experts from around the world to ensure the highest levels of protection. Proton Mail only uses secure implementations of AES, RSA, along with OpenPGP, while all of the cryptographic libraries used are open source. By using open-source libraries, Proton Mail can guarantee that the encryption algorithms used do not have clandestinely built-in back doors.

Proton Mail in the press:
“Proton Mail is a Gmail-like email system which uses end-to-end encryption, making it impossible for outside parties to monitor.” Forbes

“A new email service being developed by a group who met at MIT and CERN promises to bring secure, encrypted email to the masses and keep sensitive information away from prying eyes.” Huffington Post

■ マーケットレビュー
  • Gメールよりプライバシー保護向け 極めて優れたメールです。有料もあるけど無料でも使えます。また、VPNやカレンダーが実装されたことにより親和性も向上。

    ただし、英語ができない方は使うのをやめたほうがいい。残念ながらそうとしかいいようがない。

    Gメールやヤフーメールがあるのにあえてプロトンを選ぶのは、プライバシーのため、です。脱グーグル。そのために存在するシステムです。逆にいうと脱グーグルに興味がないのならば、使いこなせません。
  • 情報漏洩しない安心感 フリーメールはG社を使ってきましたが、裏で情報抜かれるのが気持ち悪くなり調べてこちらを見つけました。プラットフォーム使い勝手良い。フォルダが無料で3つしか作れないのは残念ですが、そのうちVPNとあわせてアップグレードしようか考え中。
    短所?としては、アプリ版で検索しても検索結果に出てこない時がある(ブラウザでは出る)位です。
  • Did they abandon the app? I don’t know what’s up with this app but despite my notification settings it no longer sends me the alerts that I need for the important emails that I have to be sent to this mailbox.

    Furthermore, when I finally discover the hundreds of emails that I’ve missed, I mark a number of them and then delete and though it looks like the app is working through the commands I’ve sent, it shows everything as completely untouched.

    Did Protonmail abandon the app to be web-based only or am I missing something?
  • デベロッパの回答 Thank you for taking the time to review our app. We apologize for any inconvenience these issues might have caused you. Our development team is aware of them and they are actively investigating potential causes and solutions.

    In the meantime, we can offer some troubleshooting steps that may help resolve the notification issue. Please make sure that the ProtonMail app is fully closed in the Tasks/Apps menu. After you have made sure that the app is shut down, please navigate to your device settings, find the ProtonMail app, disable notifications and background refresh, and then re-enable them. Please let us know if this helps.

    Additionally, please note that we are working on a complete redesign of the ProtonMail app. The new version of the ProtonMail app will have a more modern look and feel, improved functionality, and plenty of new features. In fact, the new version of the app is already available for beta testing. If you haven't already, you can learn how to join the beta here: https://protonmail.com/support/knowledge-base/ios-mobile-beta/.

    If you need any additional help, please reach out to us at https://protonmail.com/support-form/.
