Chat designed for privacy

Protections that go beyond encrypting messages.

You expect a secure chat app to have one on one and group conversations. You expect always-on encryption. You expect we can’t read your messages. You expect we don’t store messages—or any data—on our servers. If you can save files, they should be stored securely. These are the basics.
SKY ECC goes beyond the basics. SKY ECC has self-destructing messages, flash messages that expire in 30 seconds, secure audio messages, stealth mode, emergency password, and message privacy controls built in. Your messages are 100% private, we can’t read your messages under any circumstance. We encrypt your metadata in transit. We don’t store data on our servers. Our number one priority is your security and privacy. Period.
All of these features are in a modern interface that’s easy to use from day one. SKY ECC is powerful secure messaging in a zero-learning curve package.

Trusted, Private Contacts

You manage your own contact list, not a directory server. Add, approve, and reject contacts to build your private network.

Security is based on trust. Your SKY ECC ID is randomly generated and only you know it. Your ECC ID can’t be discovered through the app—you have to give it to someone or share it through a mutually trusted contact. Before someone can chat with you, you have to approve their contact request. If someone breaks that trust, you can delete and block that contact.Your SKY ECC contacts are a trusted group of people because you’re in control of your contact list—not us.

Installed on Tamper-resistant Hardware

We protect the device to protect the app.

We use devices with tamper-resistant hardware and OS-level protections built-in, then we apply device management policies to lock down features that could compromise your security or privacy. The devices we choose not only have to have tamper-resistant chips, but also come from manufacturers with a proven record of not weakening protections with backdoors.
Only when the device is secure is SKY ECC installed within a protected container on the device.

Security at Scale

A network of servers around the world making sure SKY ECC works wherever you are.

SKY ECC runs on a secure, distributed global network so you can chat in privacy wherever you are. Sky uses SIMs from global carriers so you have data access around the world to work where you work.
Our SIMs connect through a private tunnel to our servers to prevent eavesdropping at any level. Wi-Fi connections are secured immediately, no gaps. SKY ECC prevents you from logging into the app if the connection is insecure. From the first packet to the message itself—your connection and data are secure and encrypted

Don’t compromise on your privacy.
