We made private messaging easy.
Cyphr is a free, easy-to-use, encrypted messaging app for Android and iOS. All messages are encrypted, private and 100% yours. Create a free account, generate your public and private key pair, and start messaging.
Only you can read your messages.
Cyphr is a zero-knowledge messaging app. This means we cannot read, decrypt or share your messages. Cyphr generates a unique public and private key pair so only you and your friend can read your conversation - not us, not your wireless provider and not 3rd parties.
Multiple layers of security.
When you use an unencrypted messaging app or traditional SMS/MMS messaging, you are essentially putting your messages in a mailbox that anyone can access. When you use Cyphr, you gain multiple layers of security. Imagine everyone has a mailbox that requires a public key for inserting mail and a private key for withdrawing mail.
Only your friend has the private key to the mailbox so only they can open it and unlock your message.
Be as private as you want to be.
Whether you are a casual user or a privacy fanatic, Cyphr allows you adjust the privacy settings that fit your needs. You are in control of your personal information and can enable or disable features that require it.
