Olvid

Olvid represents a significant technological breakthrough in the world of secure messaging. While most "secure" messengers encrypt the content of your messages, they often leave the metadata (who is talking to whom, when, and from where) visible to their servers. Olvid is the first messenger to also encrypt the metadata, meaning not even the Olvid servers know who is communicating with whom.

Developed in France by cryptography experts, Olvid's security model has been validated by ANSSI (the French National Cybersecurity Agency), earning it the prestigious CSPN certification. This level of validation is rare in the consumer app market and makes Olvid a top choice for government officials, executives, and privacy enthusiasts.

Olvid operates entirely without a central directory. This means you do not need a phone number or email address to create an account. Connections are established by physically scanning QR codes or exchanging manual codes, creating a "web of trust" that is immune to mass surveillance or directory hacks. This decentralised approach ensures that your social graph remains private and stored only on your device.

The app is free to use for messaging. A paid version (subscription or one-time purchase) unlocks advanced features like secure voice calls and multi-device usage. By removing the reliance on phone numbers and centralized servers for contact discovery, Olvid offers a level of privacy that exceeds almost all other competitors.
