Can you compare the privacy and security features of WhatsApp and Olvid? which one's more robust?

Here’s a detailed comparison of the privacy and security features of WhatsApp and Olvid as of early 2026:
WhatsApp
End-to-End Encryption (E2EE): WhatsApp uses the Signal Protocol for E2EE, ensuring that only the sender and recipient can read messages. This is the gold standard for secure messaging.
Strict Account Settings: A new “lockdown mode” bundles multiple security features into a single toggle. When enabled, it blocks messages, media, and attachments from unknown numbers; silences calls from non-contacts; disables link previews; restricts group additions to approved contacts; hides profile details; and enables two-step verification.
Advanced Chat Privacy: Prevents others from exporting chats, auto-downloading media, or using messages for AI features, adding an extra layer of protection for sensitive conversations.
Passkey-Encrypted Backups: WhatsApp now supports passkey-encrypted backups, enhancing the security of stored data.
Metadata Collection: While message content is encrypted, WhatsApp (and Meta) still collect metadata (e.g., who you message, when, and for how long), which can be used for analytics and targeted advertising.
Phone Number Requirement: WhatsApp requires a phone number for registration, which can be a privacy concern for some users.
Olvid
End-to-End Encryption (E2EE): Olvid also uses E2EE, but with a unique cryptographic engine that mathematically proves the integrity, confidentiality, and anonymity of communications. Both message data and metadata are encrypted on the sender’s device and only decrypted on the recipient’s device.
No Personal Data Collection: Olvid does not require or collect any personal data (no phone number, email, name, etc.) for registration or operation, ensuring true anonymity.
ANSSI Certification: Olvid is the only messaging app to receive Security Visas (CSPN certifications) from France’s National Cybersecurity Agency (ANSSI), attesting to its robust security and privacy guarantees.
Decentralized Architecture: Olvid’s design ensures that even if its servers are compromised, the security of user communications remains intact. The server does not play a role in security, which is handled entirely by client-side cryptographic protocols.
No Metadata Leakage: Unlike WhatsApp, Olvid encrypts both message content and metadata, preventing any third party (including Olvid itself) from accessing communication patterns.
Which is More Robust?
For most users: WhatsApp’s new security features (Strict Account Settings, Advanced Chat Privacy, and passkey backups) significantly improve its security posture, making it a strong choice for everyday use—especially if you enable all available protections.
For maximum privacy and security: Olvid stands out due to its ANSSI certification, true anonymity (no personal data required), and encryption of both content and metadata. Its decentralized architecture and cryptographic guarantees make it the more robust option for users who prioritize absolute privacy and security, such as government officials or those handling highly sensitive information.
Summary Table:

Conclusion:
If your priority is convenience and you trust Meta’s ecosystem, WhatsApp’s latest features make it much more secure than before. However, if you need the highest level of privacy, anonymity, and security—especially for sensitive communications—Olvid is the more robust choice.
