How secure is my communication and information with appear.in?
The video and audio communication in an appear.in room is only visible to participants inside a room. It is not possible for other users to listen in to the communication unless they are present in the room themselves, in which case they will be visible for everyone in the room. It is possible for anyone who can guess a room name to enter an open room. If you want to prevent others from coming into the conversation, you can lock the room by clicking the lock button in the menu. No new participants will then be able to enter the room. We have a feature where a new participant may "knock" on a room, and be presented to the user's in the room with live video. However, no video is broadcasted back to the user in this case, and the feature may also be disabled completely for some rooms.
To control the room, we recommend claiming ownership of it. Then you can keep the room locked at all times, so no one else can enter it. For a team use case, the person who claims ownership of the room can add people as members, and they will then be able to access the room even when it's locked.
As for saving data we store as a little as possible about the user. Our main goal is to create a service that is fast and reliable and to remember you when you choose to claim a room. :) Basically the only thing we are going to know about you is what you voluntarily tell us (e-mail address and phone number if you choose to claim a room or sign up for premium, background pictures/content for the room, etc). No video or audio is ever saved our servers. Also we don't partner with third party vendors and sell user information for targeted marketing. We believe we are part of team with our users and respect your privacy as any good team should. You can reference more of our security and privacy standards in our Terms of Service as well!
All communication between your browser and appear.in is transmitted over an encrypted connection (SSL). Video and audio transmitted in the service is sent directly between the participants in a room and is encrypted (SRTP) with client generated encryption keys. In some cases, due to NAT/firewall restrictions, the encrypted data content will be relayed through our server. We take pride in collecting and storing as little user data as possible in the service. We believe that these properties make appear.in one of the most secure and eavesdropping-resilient video conferencing services around. More information on our encryption practices including our premium version is available within our Terms of Service.
