Olvid, the most secure messaging app in the world. Olvid guarantees the total and definitive confidentiality of exchanges, relying solely on the mutual trust of interlocutors. For the first time, security does not rely on trusted servers. No identification element is ever transmitted to the servers: the exploitation of personal data is not possible, neither by Olvid, nor by a third party. Olvid protects you from unsolicited messages since the only users who can send you messages are the ones that you decided to accept within your private network. No more spam ! At the heart of Olvid, a 'cryptographic engine' coming from 5 years of research allows us to mathematically prove the integrity, the confidentiality and the anonymity of your communications.
