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.

cothalesr ,

great improvements in the last year

one area for improvement is in the new conversation UI.

There’s too many rich messaging options that i would never use. two separate buttons for document scanning and document upload? that’s very silly. maybe let use choose which buttons should be on the bottom bar?

Developer Response ,

Hi cothalesr 👋 !
Thank you so much for taking time to write a review for Olvid!
We heard you. The rich messaging options can now be reorganized at your will, making more accessible the buttons you use the most. You can further customize this area by choosing your preferred quick emoji (globally for the entire app, with possible overrides by discussion). We hope you will like these improvements!
Have a great day and thank you again for the review 🙌.
