The Cyph beta is currently invite-only, but has a free tier and premium plans (we intend to always have a free tier, because we see online privacy as a basic right).
Ephemeral Cyph Burner is free to use just by sending a link as well.
Contact us for custom solutions and partnerships.
Currently, we only track numbers of: cyph sessions, messages, timeouts, voice/video calls, file transfers, signups, cyphertext UI views, help UI views, and calls to our API.
Click the plus ("+") icon in the message composition textbox, then click the video (or phone) icon. A warning will pop up confirming that you wish to send the call invite and that connecting will expose your IP (Cyph video uses a peer-to-peer connection for voice and video, so you will be connecting directly to the other party instead of going through our servers).
Simply go to cyph.im or click the "start new cyph" button and a cyph link will be generated for you to send to a friend. Text, email, or send the link to them via any other channel, and when they click it you both will enter a secure chat.
Click the plus ("+") icon in the message composition textbox, click the paperclip icon, and then select the file you wish to share.
