Everyone's favourite privacy-loving cat is now on iPhone! Get an encrypted cat in your pocket, have private chats with friends any time.

“Cryptocat has a simple, countercultural goal: people should be able to talk on the Internet without being subjected to surveillance.” — NYTimes

16th Annual Webby Awards Honoree, Social Media Category. — Webby Awards

Cryptocat lets you chat with privacy. It encrypts your chats and you already know how to use it.

Easily have group conversations with your friends without fearing monitoring or interception. Cryptocat is free, open chat that aims to provide an open, accessible Instant Messaging environment with a transparent layer of encryption that's easy to use.

Cryptocat is developed by privacy advocates, for privacy advocates. Big Data providers continue to amass gigantic amounts of personal information without providing any guarantee of privacy, while encryption remains largely inaccessible. This means that a lot of what you do online is not within your control, but rather susceptible to governmental or corporate interception.

Cryptocat aims to bridge the gap for those who need encrypted communications that are easily accessible.

What's New in Version 1.02

■ Fixed a bug that could cause crashes when initiating private chats or verifying fingerprints.
■ Fixed a bug that wouldn't allow underscore characters in nicknames or conversation names.
■ Autocorrect has been disabled to prevent potential caching of words of messages.
■ Fixed a bug that would make the iOS app icon look less appealing on devices.

Customer Reviews

Clean, works, is presumably secure, but misses a key piece of functionality

The app is pretty, and it works simply to send and relieve messages. According to cryptographic reviews I've read, it is presumably secure (I'm no expert on that, sadly).

My complaint is that it's impossible to have more than one chat at a time. This is somewhat a feature since it forces you to log out and in the process purges your previous conversation, but it also means you can only have one conversation at a time. I'd very much like to have the option to carry on multiple conversations.

Almost Perfect

This app would be perfect if it didn't log you out after a couple minutes in the background. As messages are not saved when you are not logged on, this renders the app useless as an everyday messenger, and makes it approximately equivalent in utility to an IRC client. I love, love, love this app. Just put a passcode lock on it when you move it to the background and don't have a timeout. Please!! Then I will recommend this app to all my friends.

An encrypted chat your grandma can use

Love the simplicity, works straight out of the box., and is very secure.

it lacks a bit in features: adding the option of using a passcode lock would allow for non-simultaneous conversations and multiple conversations

There is a bug: the first time you open the app it does not work; restarting it fixes the issues
