Description
Proton Mail's all-new encrypted 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 • Send and receive Gmail emails directly inside Proton Mail • 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 inbox is secured across all your devices. No one can read your emails but you. Proton protects your data with zero-access encryption and end-to-end encryption between Proton users or with password protection. • Unmatched protection — We offer strong phishing, spam, and spying/tracking protection.
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 Easy Switch Migrate from Gmail, Outlook, Yahoo, iCloud Mail or AOL to Proton Mail in just a few taps. Your messages, calendars and contacts are transferred automatically, so you’re up‑and‑running in moments—without any manual exporting or importing.
Gmail Auto‑forwarding Enable auto‑forwarding from any number of Gmail accounts and funnel all the emails that matter into your Proton Mail inbox. Preserve Gmail’s convenience while adding an extra layer of privacy protection.
Proton Mail in the press:
“Proton Mail is an 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 from MIT that met at CERN promises to bring secure, encrypted email to the masses and keep sensitive information away from prying eyes.” Huffington Post

Comments on Proton Mail: Encrypted Email for Android
★★★★★Ċymber Michele· Jun 29, 2026
Having traveled the world, it amazes me that only a few places respect privacy. Thank you Proton.

I've only signed up for a couple of days now, came from Tutanota (German) email client that's a lot like Gmail but extremely more secure. I left Tutamail doesn't allow you to swipe left or right to go fwd or back to the next message. I don't intend to use Proton mail often. It's a backup. Instantly I 😍 the UI and dark color themes. Really easy to navigate. Every couple years I perform a deep search to see who has the best free client. I hadn't previously used PM. Reddit's reviews are stout though!
★★★★☆Rebecca Wright· Jun 20, 2026
I like this email except you can't access without internet. Even mail that's already in your inbox.
★☆☆☆☆Canadoug Toronto· Jun 16, 2026
Stop working entirely. FAIL. Also, sleazy advertising trick. In the app interface, the upper right corner shows an icon with a typical alert dot on it. In fact, it is not an alert dot... it is built into the icon. It is designed to get you to press it to see their upgrade offer. The dot can not be turned off, and is just there to fool you into pressing the icon. This is bad interface design, deceptive, and annoying. I expect better of an otherwise reliable company than cheap trick.

Sorry to say, but I found some errors like creating account error, Verification process error even I connected my email account with this software but am unable to see my any single mail from G-mail.
★☆☆☆☆R7Droid· Jun 25, 2026
I like the idea about Proton, but I thought it was kind of poor in terms of stability. When I tried to send a mail into my Gmail, it was not sended. Next, when I send a mail into my Proton Mail account using my Gmail, it was also not sended. I didn't exactly know why, as mails from other such as those from Simple Login is there without any delays or flaws. I hope that there will be a fix to it. Proton, pls hear me 🥲

Can't read any emails. The subject is clear, but when you open it, it's just a bunch of random code, symbols, and other junk.
