{ -brand-short-name } supports end-to-end encryption of one-to-one conversations. This prevents third parties from eavesdropping on a conversation. End-to-end encryption can only be used when the other person also uses software that supports OTR.

When requiring end-to-end encryption, messages in one-to-one conversations will not be sent unless they can be encrypted. Received unencrypted messages will not be shown as part of the regular conversation, and not logged either.
