Description

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 Follow Proton on social media for all the latest news and offers: Facebook: /proton Twitter: @protonprivacy Reddit: /protonmail Instagram: /protonprivacy Our open-source code base: https://github.com/ProtonMail EULA: http://www.apple.com/legal/itunes/appstore/dev/stdeula

    I like both the app and the desktop version. Spam management is absolutely amazing.
  • Buggy Update

    An otherwise excellent app, since the last update content in emails from Capital One and Verizon opens in the web version but not in the iPhone or iPad app versions.
  • I Have So Had It With This App

    Clunky, annoying, sometimes trash does not empty like it used to (and, yes, I am emptying the trash correctly), latest update is not showing my messages, tweaked the Privacy & Security to see if that helped - nope. Ugh!
  • Good mature privacy focused solution

    The product works well for keeping your conversation private. I like using the app but there are nuisances especially on the UI side as it’s not very user friendly. I would like to see a more streamlined UX design. For example give ability to remove sender images for the inbox. No I do not want to see the sender initials either. Add function to set number of rows to preview a message. Add ability to color code different accounts. Remove the delete message confirmation. Small things but would make user experience and aesthetics much better.

    Yubikey recently not recognized in iOS 26.1
  • Clunky, background sync does not work

    Background sync does not work correctly with this app. I often find notification bubbles showing incorrect unread counts after I’ve already addressed the message elsewhere (web, etc) and the changes are also not reflected in my inbox, I always have to manually pull down to do a sync. Swipe actions also don’t always work, the message will just stay there visually and I again need to manually pull down to make it update in the message list. Needs work.
  • Still missing some of the best of the old version.

    Edit 12/3/2025. Seriously! You need to restore the export to pdf before I run out of storage space. There are no other usable options to save 100 message conversations and I don’t want to have to start deleting them with no export. It’s not a new feature! It’s something that was in the old version and that you removed. Please put it back now! I updated my iPad version today, hoping that some of the disaster from the recent version had been fixed. The version notes say that we can change the font size of messages. Not on the iPad you can’t. The same issues and a new one are there. Can’t increase the font size above the tiny setting. Can’t decrease the wait times after sending. It still stuck on 10 seconds. What happened to export to pdf? That was a great feature that’s just gone. This latest update for iOS is another disappointment. Doesn’t anyone read the reviews? People have been screaming about how you destroyed a great app since the new version was rolled out two months ago.

    I tried to sign up for unlimited through apple I was charged 3 times but still says I have free subscription. I attempted to report issue through proton app and after filling it out it wouldn’t allow me to submit. Been using proton for 15 years. Never again
  • We have to manually mark each email as ‘read’ now?!?!

    By AsleepT
    Read emails stay bold (marked uread) now. It’s ridiculous for us to have to manually for each email click through actions to mark them as read, instead of them being marked read after, you know, they have been read. Sheesh. It’s like it’s 2005. Give us an option in the settings menu to have emails automatically marked ‘read’ after 5 seconds or whatever time period.
  • No Spam! Great!
