Zenit-Polar

Turn any message into your own secret code. Create custom ciphers only you and your friends understand — completely private, playful, and yours to control.

BIG UPDATE: iMessage native integration!

Ever wished you had your own secret language?

Zenit Polar turns any message into a private code, instantly. Type it, dictate it, or paste it in, and watch it transform right before your eyes. Only people who know your cipher can read what you wrote.

MAKE IT YOURS Do not just use our cipher, build your own. Pick any letter pairs you want and create a substitution code that is completely unique to you and your circle. Make one for your best friend, your family group chat, or just for the fun of it. Share it with a single tap, so anyone with the app can use the exact same cipher too.

SPEAK IT, DO NOT TYPE IT Dictate your message out loud and watch it appear in real time, no typing required. Choose your dictation language independently from the apps interface, so you can write in Portuguese while speaking Japanese, or any combination you like.

STAY ORGANIZED Group your secret messages into named, color-coded conversations. Keep your Surprise Party plans separate from everything else, search your full history in seconds, and never lose track of what was said to whom.

SPEAK YOUR LANGUAGE Fully available in English, Portuguese, French, Spanish, Italian, German, Japanese, and Chinese, with a unique aurora-inspired color palette for each one.

YOUR MESSAGES STAY YOURS Everything is stored locally on your device. No account, no sign-up, no servers holding your secrets. What you write is yours alone.

Whether you are passing notes with friends, playing a code game, or just love the art of cryptography, Zenit Polar makes secrecy simple, playful, and beautifully yours.
