Decoder Ring · Secret Codes vs Fulgor

Decoder Ring turns any message into a secret code only your friends can crack. Type what you want to say, tap Encode, and share the gibberish to any chat app. Your friend pastes it back in, taps Decode, and reads your real message. No accounts, no servers, no one else can read it. HOW IT WORKS Every word in your message is looked up in a shared dictionary and replaced with a word based on your cipher number. "hello" becomes "hematologist." Your friend's app shifts it back using the same cipher number to recover "hello." Punctuation, emoji, and names pass through untouched. FOR EVERYONE • Encode or decode any text instantly • Preserves capitalization, punctuation, and emoji • Share directly to Messages, Mail, or any chat app • Beautiful light and dark modes UPGRADE TO PLUS • Change your secret cipher number — pick any number from 1 to 10,000 • Switch between multiple word dictionaries, including British and American English • No ads ADD CONTACTS Save up to ten friends or group chats, each with their own cipher number and dictionary. One tap translates for a specific person — no more setting the dial by hand. AUTO-SHIFT Give each contact a living cipher. Their cipher number bumps by one every day, so yesterday's code is already stale. Perfect for ongoing games, daily challenges, or just making a spy thriller out of your group chat. Enable the companion watch app for synchronizing instant cipher number changes. POLYGLOT (COMING SOON) Take it further — translate the shifted word into Spanish, French, or German before sending. The recipient's app reverses both steps. PRIVACY YOU CAN SEE Decoder Ring runs entirely on your device. There are no accounts to create and no servers to trust. We don't collect, sync, or transmit your messages. The word list lives in the app bundle; everything else lives in your phone's private storage. NOT REAL ENCRYPTION — JUST FUN Decoder Ring is a toy cipher, not a security product. Anyone who knows your cipher number and dictionary can decode your messages. Don't use it for anything you actually need to keep private. QUESTIONS? Email support@decoderring.app Privacy Policy: https://decoderring.app/privacy Terms of Use: https://decoderring.app/terms
