About Cyphr
Cyphr - Encrypted messaging simplified.
Cyphr makes encrypted messaging easy. All messages are encrypted, private and 100% yours. Generate your public and private key pair so only you can read your messages, start group conversations with friends, and share attachments privately.
ONLY YOU CAN READ 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 phone company, and not a 3rd party. We take a zero-access approach, and give you total control of your data.
BE AS PRIVATE AS YOU WANT TO BE. Whether you are a casual user or a privacy fanatic, you can adjust Cyphr's settings to fit your privacy needs. If a feature requires information sharing, you can choose to disable that feature.
PRIVACY WITHOUT SACRIFICES. Cyphr doesn't sacrifice simplicity or features for privacy. Start single or group conversations, send attachments, and more.
WE DON'T STORE DATA ABOUT YOUR MESSAGES. We do not needlessly store information about you, your recipients or your messages.
MULTIPLE LAYERS OF SECURITY. Cyphr encrypts your messages using a combination of symmetric keys, and public and private key pairs. Cyphr also verifies messages with public key verification to ensure you and your friends know messages are from each other, not an impersonator. All messages are transmitted securely with SSL/TLS to protect your personal data, in addition to the message.
YOUR MESSAGES. OUR SERVERS. NO 3RD PARTIES. At Golden Frog we own our servers, write our code, and manage our own network to deliver the highest levels of security, speed and privacy. Cyphr servers are located in Switzerland for maximum user privacy and protection.
A COMPANY YOU CAN TRUST. Golden Frog's founders are Internet veterans who have fought to preserve online privacy, security and freedom since 1994. We arm users in 195+ countries with VyprVPN, a secure personal VPN, Dump Truck, a secure online storage solution, and Cyphr, the world's most secure messaging app. Together these tools allow users to protect themselves online, wherever they go.
HELP US BUILD THE APP YOU WANT. Leave your Cyphr feedback and feature requests so we can make the best encrypted messaging app for you.
UPCOMING FEATURES:
• Multi-device capability

Had an issue with Cyphr crashing when searching for a contact. Support was generally pretty fast to respond, but did not seem to read the dialog. (Apr 17th) After a delay they got back to me with a follow-up to double check permissions, appears the application is not requesting the required permissions but after manually granting, it seems to work like a charm.

You guys are the gift that keeps on giving. The app is great and I patiently await new features. UPDATE :However when I take a picture in the app it looks awful. I'm guessing that's due to compression ? Anyway everything else seems fine. UPDATE 2: Notifications don't seem to be working. I need to open the app to receive messages

The field for the passphrase in multi device support only allows 12 characters. My passphrase is a sentence and works fine on the Web app and iOS. Can't use the android app at all.

Initially I suffered from what appeared to be an irreversible login bug. I took all recommended steps to resolve it with no luck. Then I disabled VyprVPN (coincidentally using the server located in Switzerland, like the servers for Cypher), and it worked.
