Inky - Secure Email

By Inky

Open iTunes to buy and download apps.


Inky, the groundbreaking mail app that makes exchanging end-to-end encrypted mail with your existing Exchange and IMAP email account as easy as sending a text, now lets you send end-to-end encrypted emails to anyone.

Just install Inky and enter your email address and password (or use oAuth for Gmail accounts.) Inky will verify your account within 60 seconds, after which you can exchange encrypted email.

There are no keys, certificates, or fingerprints to manage: encrypted email with Inky works exactly like legacy insecure mail – the difference is that only the intended recipients can read the emails you send. Inky handles all the key and certificate management for you – so you don't have to be a crypto expert to send secure mail. It just works.

When you opt to encrypt email to someone who doesn't have Inky, that person will receive an email with a secure link to view the message on the web. After clicking this link, they will prove they control their email account by simply entering their email address and clicking on an authorization link in a follow-up email. They will then be shown the secure message, decrypted on their local device (keeping the message completely end-to-end encrypted.) They can also securely reply via this web page. Your recipients do not need to install anything or remember a password.

Inky's encryption technology is based on the S/MIME standard. Inky encrypts emails with AES-256, deemed suitable for classified communications at the Top Secret level by the US Government. Your private keys are kept secret, and nobody but you has access to them – not our employees, your email host, or anybody else.

Of course, Inky offers all the email and calendar features you'd expect from a modern email client – an elegant design, speedy search, and timesaving features like quick replies. You can even search your inbox with hashtags like #pdf and #package with results returned instantly, as you type. Give Inky a try, and let us know what you think by dropping a line to

Working great

This version is much better than the previous versions. Along with all the new features, many major bugs are fixed and it runs great. I am now getting push notifications like I should be. Great work from the Inky team.


If you're anyone that uses email even if only once a day this app is amazing!
