Olvid is a French secure messenger with a distinction no mainstream app can claim: it is certified by ANSSI, the French national cybersecurity agency, through two CSPN security evaluations. Unlike WhatsApp or Signal, Olvid requires no phone number, email, or personal data at all: identities are pure cryptographic keys exchanged between contacts.

Because there is no central user directory, there is nothing to breach and no metadata graph to exploit. Messages, calls, and shared files are end-to-end encrypted with no size limits, groups work as expected, and the app runs on iOS, Android, macOS, and Windows, even on WiFi-only devices without a SIM card.

Key features:

• CSPN certification from ANSSI, the French cybersecurity agency
• No personal data required: no phone number, email, or name
• No central directory, so there is no user database to leak
• End-to-end encrypted messages, calls, and unlimited file sharing
• Free personal use with paid options funding the service
• Multi-platform on iOS, Android, macOS, and Windows
• Works without a SIM card on any WiFi-connected device

Ideal for teams, officials, and privacy-conscious users who want WhatsApp convenience with certified French cryptography and zero personal data exposure.
