CIPHERKIN / SUPPORT

A hand with your secrets.

Cipherkin is coming soon to iPhone and iPad. Downloads and app support are not available yet.

How will messages work?

Write a note and seal it, then send the sealed text through Messages, email, or any app in the share sheet. The recipient copies it, pastes it into Cipherkin, and watches it open. Both people need the app.

Are free messages private?

No. Free Classic Cipher notes are sealed with a password built into the app, so anyone with Cipherkin can open them. They’re for fun, not for secrets. With the unlock, you can protect a note with your own password (at least 12 characters). Share that password in person or by a call, not alongside the message.

Will recipients need to pay?

No. Opening messages in every theme will always be free, including notes protected with a password. The planned US $1.99 one-time purchase unlocks creating messages with Arcane Runes, Secret Agent, Pirate’s Code and future themes, and setting your own password. Classic Cipher will be free.

What if a message won’t open?

Check that the whole message was copied, from the “CK1:” at the start to the end, and that the password is exactly right, including capital letters and spaces. Cipherkin can’t recover a forgotten password, and nobody else can either: there are no accounts or servers.
