WhisprApp - Private Chat

Whispr – Private Chat, Your Way Whispr is a privacy-first messaging app built for people who want real control over their conversations. Every message is end-to-end encrypted before it leaves your device — our servers never see your plaintext content. What makes Whispr different: End-to-End Encrypted Messages Messages are encrypted on your device using Curve25519 key agreement and AES-GCM. Only you and your recipient can read them. Burn After Read Send messages that automatically delete after the recipient opens them. Perfect for sensitive information. Disappearing Messages Set messages to auto-delete after a custom time window. No traces left behind. Encrypted Voice & Video Calls Calls are secured with DTLS-SRTP, the same standard used by Signal and WhatsApp. Your conversations stay private end to end. No Phone Number Required Sign up with just a username. No email, no phone number, no personal data needed to get started. Ciphertext-Only Backend Our servers store only encrypted payloads. Even we cannot read your messages. Delete For Everyone Made a mistake? Delete any message for all participants instantly. Encrypted Attachments Photos and files are encrypted before upload and stored as encrypted blobs — never as readable content on our servers. Your privacy is not a feature. It's the foundation. Whispr is designed from the ground up for people who believe private communication is a right, not a privilege. No ads. No tracking. No data selling. Ever.
