HushHush.

Instead of a new messaging app, HushHush is a secure layer for the ones you already have. It combines the absolute privacy of local encryption with the freedom to keep using the platforms you already love.

HOW IT WORKS:

• Type a message → HushHush encrypts it • Paste the encrypted text into any messaging app • Your contact copies it back into HushHush to read it.

KEY FEATURES:

ZERO-KNOWLEDGE ARCHITECTURE: • HushHush uses a zero-knowledge architecture to ensure that privacy is baked into the code, making it technically impossible for us to collect your data.

MINIMUM 4 LAYERS OF ENCRYPTION: • Messages protected by at least 4 layers of stacked and shuffled encryption, with the option to customise and add as many encryption layers as you would like.

QUANTUM-RESISTANCE: • Optional quantum-resistant ML-KEM encryption available, with a two-step in-person QR-code key exchange for extra security.

LOCAL AND ON-DEVICE: • Encryption keys never leave the device.

QR-CODE EXCHANGES: • Key exchanges are done In-person via QR-code scanning to prevent encryption interception.

DUAL-PROTECTION: • Messages are dual-protected by your password and a hardware-backed key stored in each device’s secure enclave. Neither factor alone can unlock your data.

DURESS MODE: • An optional duress mode is set up via a secondary password that, when used, replaces/ replaces and wipes all data with convincing decoy contacts and conversations.
