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.

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

Most email apps now quietly send your mail to a cloud AI — for summaries, smart replies, "priority" ranking. WhoMail doesn't. Your email never leaves your device for an AI service. Ever. WhoMail is a fast, genuinely private email app for iPhone, iPad and Mac that brings Outlook, iCloud, Fastmail, Yahoo and any IMAP account into one unified inbox. WHAT MAKES IT DIFFERENT • No cloud AI. Ever. Your messages aren't uploaded, summarised, scanned, or used to train anything. Anything that feels smart happens on your device. • Know your people. WhoMail builds a private picture of who you actually email — your reply times, how often you talk, your busiest hours, and a profile for each contact assembled from their own email signatures. No other inbox shows you this. • Push that stays blind. New Outlook mail arrives the second it's sent, even with the app closed — but our relay only ever learns "this mailbox got something." The sender and subject are fetched on your phone, by your phone. • One unified inbox across every account, or jump to any single mailbox in a tap. • Native and fast — opens, syncs and searches instantly, with a calendar built in. PRIVACY ISN'T A FEATURE HERE — IT'S THE DESIGN • No AI servers. No mail content on our servers. No tracking, no ads, no profile of you sold to anyone. • You sign in straight with your provider; your tokens stay in the device keychain. • Turn our push service off tomorrow and you lose nothing but a little speed. Supports Outlook / Microsoft 365, iCloud, Fastmail, Yahoo and standard IMAP. Built by Calligo IT. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
