Your calls.
Your privacy.
Only you and the recipient can hear your calls. Not even Ecall can access them.
End-to-End Encryption (E2EE)
Every call is locked with dynamic, session-only keys generated locally on your device. Nobody – not ISPs, not us – can decrypt or eavesdrop.
Fully Independent
Self-contained architecture. We never rely on tracking-heavy infrastructures from Apple, Google, or other Big Tech.
Radically Transparent
Complete operational transparency. If forced to hand over data, our system mathematically proves it has none.
Open Source
No black boxes. Ecall's entire codebase is public for independent security audits and verification.
Zero-Knowledge Server
Our servers merely relay encrypted signals. Designed with a strict Zero-Trust philosophy, we don't know and can't access your content.
How Ecall
protects your calls
Multiple layers of protection work continuously to keep your conversation private – without interruption
Encrypted on your device
Your call is encrypted before it leaves your phone.
Only you hold the keys
Encryption keys are created for each call and shared only with participants.
No one can listen
Not even Ecall can access your conversations.
Keys disappear after every call
Temporary keys are deleted when the call ends.
