About Cipheus

Is this two aliens talking? It might be. Or it might be your group chat in Cipheus. — Cipheus turns every text you send into ancient runes, celestial symbols, or geometric glyphs. Your friends with the same Language Pack see the real message. Anyone glancing at your phone sees... something they can't read. It's not magic. It's not really alien. But it kind of looks like both. — WHAT IT'S FOR - Group chats your parents/siblings/coworkers shouldn't read - Aesthetic texting (your messages look cool now) - A private second layer for conversations that matter - Just for the vibes, honestly — HOW IT WORKS Pick a Language Pack — Nordic Runes, Celestial, Geometric, and more. Share it with one friend or a whole group. Every message you send turns into symbols. Long-press to see what's underneath. It's encrypted end-to-end. Even I (the dev) can't read your messages. That's the point. — FROM THE DEV Hi, I'm Flood. I built Cipheus solo because I wanted texting to feel like a secret again. The kind of secret you and your best friend share in a language no one else speaks. I'm still adding Language Packs, fixing rough edges, and listening to everyone using it. Send feedback. I read everything. — CIPHEUS+ (Optional) Unlock unlimited Language Packs and unlimited friends. $3.99/month or $29.99/year. Cancel anytime. — Privacy Policy: cipheus.com/privacy Terms: cipheus.com/terms Contact: cipheus.com (yes I read DMs) cipheus.com
