Is this two aliens talking?
Your texts, in runes. Or stars. Or glyphs.
Pick your aesthetic — only your friends can read them.
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.

Tiny fixes, big improvements

- Faster decryption on long-press (you'll feel it)
- Fixed a few sneaky bugs that were hiding in the runes
- Made Cipheus a little more reliable for your secrets
Still figuring this out with you. Send feedback — I read everything.
