let's talk about schmoose - the secure messenger

private messaging

schmoose is a cross platform instant messenger with a passion for privacy. With end-to-end encryption you can exchange messages and media without the cost of using SMS and without the nagging feeling that someone is watching you. Your conversation stays private the way you meant it to be! It’s not just another instant messenger—with schmoose you reclaim your control over who sees your messages.

multi device in sync

schmoose is continuous communication in privacy. Whether you’re on your way to work, in the office, or going out with friends, schmoose offers you seamless communication on all major platforms and devices. Start up your conversation on the go, keep it going at your desktop, take it up again from your couch. schmoose keeps you in sync – unlike most others.

encryption and privacy

schmoose uses open standard technology for end-to-end encryption (AES-256, SHA-256, RSA with key size of 2048 bits). These technologies guarantee privacy—you’ll feel good again about texting confidentially with your friends and colleagues. With the OpenPGP standard in place, schmoose provides the ready environment for you to conduct truly private communication based on proven technologies. Data is only exchanged using a secure line (128-bit TLS 1.2). No one else can read your schmoose messages, not even us, and that’s the way it should be!

fast and easy to use

schmoose bundles encryption with convenience. Encryption doesn’t need to be gray and complicated anymore (though encryption software and services usually are). We’ve crafted schmoose into an extremely user friendly messenger app. Enjoy privacy without having to worry about security—we take care of that. It’s a gratifying user experience built on reliable technology – schmoose.

I wanna know what schmoose is, I want you to show me

So, where to start?

When starting the app for the first time, you need to enter either a valid email address or a SMS-capable phone number. At that time, schmoose has already created a public/private key pair on your device. The data you've just entered will then be encrypted and signed before it is sent to one of our servers.

What's in a name?

We originally wanted to go with "schmooze" as in, "have a friendly, private conversation". But legal said no, so instead we went with "schmoose" – pronounced /ʃmuːz/, which for us was pretty much the same thing. That was when localization threw up their hands, so we boldly embraced our inner moose – that noble, fiercely private beast.

How safe are my messages?

Your messages are still kept private, even if someone listens to the message traffic and tries to understand (i.e. decrypt) what’s going over the wire. Schmoose relies on transport layer encryption as well as message level encryption in order to provide a high degree of privacy to its users.

When will schmoose be available?

We’ll release the various versions as soon as possible, because the world needs schmoose! Stay posted by following our development timeline on twitter and facebook.

How do I connect to other people?

You can synchronize your address book with the server-side schmoose directory. This simple process will send hash values of the email addresses and/or phone numbers of your address book contacts to our server-side schmoose directory. For each match, the server will send back the individual schmoose ID of the found contact as well as the corresponding public key(s).

How do I connect to other people in a trusted way?

You receive the schmoose ID from your intended messaging partner through any external channel of your choice (phone, email, slip of paper, face to face …). You enter your counterpart’s ID into the schmoose app, which then retrieves your contact’s corresponding public key from the schmoose server. If you’re able to meet your messaging partner face to face, you can directly exchange your schmoose IDs and public keys by scanning each other’s schmoose QR code.

Why not Open Source?

Well, we decided to start closed source, considering that schmoose is a product that could eventually help pay our bills. But we don't preclude the future possibility of sharing portions of our codebase with the Open Source community. We intend to have trusted experts with the right background and knowledge in software security analyze our product’s source code for any potential flaws.

Why not use OTR?

OTR requires the recipients of a message to be online for a session to be negotiated. This falls short of the requirements of real-world mobile-to-mobile messaging, where connectivity gaps and offline periods are still all too common.

What happens after registration?

We’ll promptly send you an email containing a short code to validate your email address. When you open the schmoose app on your device, you’ll be requested to enter the code, which will then be securely transmitted to the server for verification. If you’ve specified a phone number rather than an email address, we’ll send a short message to that number. This message also contains a code for completion of the validation process. If the SMS or email (check your spam!) doesn’t reach you, just request a phone call. A gentle voice will then tell you your code. It does not help to delete and reinstall schmoose!

How do I individually connect to other people?

In order to connect to other people individually, without synchronizing your address book, you simply tap in the phone number and/or email address of the contact you want to chat with. A hash value is calculated and sent to one of our servers to be looked up in our global schmoose directory. If a corresponding contact is found, the server will send back the individual schmoose ID of the found contact as well as the corresponding public key(s).

Can anyone else read my messages - maybe you?

Your messages are encrypted on your device using the public key of the receiver(s). Only encrypted messages leave the sender’s mobile device.
Only the intended receiver is able to decrypt your message back into readable format by using their private key. Because all private keys are created on the users’ devices and never leave these devices, schmoose is unable to decrypt your messages into a readable format.

Where are your servers located?

Currently, our servers are located in data centers across Germany / Europe.

Why should I trust you?

Because we are building the messenger we always wanted!

What do I need a password for, and when?

To use more than one device, you need a master password. This ensures that you are the correct recipient of the same messages on your various devices. You’ll also need this master password later on to transfer your schmoose access to a new device – so you can remain the same user and preserve your previous contacts and chats.

If you use an Android device, you must always enter a password when starting the schmoose app. This prevents any unauthorized person who may have simply copied your whole device from being able to read your messages.

Please make sure to remember your password well! We cannot help you if you lose it!
