One major goal of the AllNet project is, by design, to provide users with privacy in their chat communications. All interpersonal (non-broadcast) communications are encrypted using a key generated on the device itself. The secret part of the key is never shared or transmitted in the clear by AllNet.
By design, the content of all communications is hidden from all but the sender and intended receiver(s). No information, other than the fact that transmission is taking place, is available to any other device.
All key material and all chat records are stored unencrypted on the device (they are in your home folder's .allnet folder). Depending on the security provided by your device, they may be available in backups or to anyone who gains access to your device.
If there are errors (bugs) in the design or implementation of this software, the AllNet security goals may not be accomplished. If this happens, others may have access to your confidential information, including the contents of chat messages and they keys used to generate and read encrypted chat messages.
Encryption is morally neutral, and can be used by morally upright and morally depraved people alike. Each user of AllNet is responsible for the use to which they put the software. The developers strongly prefer that AllNet only be used in ways that do not harm other people, but have no power to compel their users to do so.
