The IM+ team wants your messages to be super-safe

Sicher, a new "super-safe" messenger has arrived today on Windows Phone, iPhone and Android devices. Sicher (pronounced "Zee-her") comes from the team behind IM+ and brings free, encrypted chats and file transfers to users. Using the app, you'll be able to chat, send files, photos and voice messages to other users. Sicher goes so far as to not show incoming messages on your lock screen (only an alert) so you have to open the app to get the full message. Sicher features secure end-to-end encryption of messages, files and group chats, anonymous push notifications and self-destruction message settings.

Only your peer, the holder of original private key, can decrypt the message you sent. Moreover, once your peer receives the message, we delete all of its traces from our servers. And there's a self-destruction timer for everything you send, as well as an option to force-purge existing conversation. The only way for third-party to see your communication is the app on your smartphone, so if Sicher is your primary secure messaging tool, we recommend to set a device-level password in application settings to prevent unauthorized opening of the app. The password itself and the data stored on device are also heavily encrypted.

Nothing is stored on servers, so once your messages are delivered, any trace gets deleted and it can only be read by the recipient. Sicher uses contact matching via phone numbers in your address book to find your friends, so you'll have to have some digits before you can start chatting things up with your buddies.

Sicher is available now as a free download from the Google Play Store, though future versions may offer in-app purchases for non-core functionality.

Sicher from the IM+ team promises to keep your messages 'super-safe'


"Sicher (pronounced "Zee-her")"...

Because of course it is. Not that it matters, because everyone will just call it "sit-cher."

No, this appears to be a full-service chat application (like BBM), not a replacement for your SMS app. Both people will need to be using the app to be able to communicate.

I love how companies are using the whole NSA thing as an excuse to make their apps more secure. As if a simple court order wouldn't have them handing everything over to the authorities... Nothing gets stored on servers you say? It would if they were told to.

Q for those in the know -
Was Blackberry storing the messages in servers or not?
All I remember is when the riots broke in London 2010 , since time after Scotland Yard forced them to turn in all conversations while actual gathering took place and made sure that in the future they have timely access to it.
