Murmur Input: Encrypt Messages

Murmur Input adds on-device text encryption to your everyday typing. Write in the keyboard, turn your message into encrypted emojis, and send it through your chosen messaging app. Copy a supported encrypted message and tap Read/Paste to read it inside Murmur's keyboard. Connect with other Murmur users through a shared-key QR invitation or private ECDH pairing. Both participants need Murmur and the matching key or completed pairing. Murmur prepares messages; you choose when to send them in your chat app. Type in 11 languages: English, Chinese (Simplified and Traditional), Spanish, Russian, Arabic, French, German, Portuguese, Italian, Turkish, and Korean. All 12 keyboard language options are free. Use offline dictionaries, optional local word learning, keyboard size controls, and light or dark appearance. Free includes 3 QR key slots and 1 ECDH key slot. The ECDH slot holds a one-to-one pair or a received group invitation. Premium is an optional lifetime purchase for more key storage and creating private groups of 3–10 people. Storage capacity depends on key size and secure-storage limits. There is no subscription. Optional developer-support purchases are separate and do not unlock Premium. Encryption, decryption, and dictionary lookup run on your device. No Murmur account, advertising, or cross-app tracking.
