## What is Cipherkin?

Cipherkin turns a short note into a sealed message you can send through any app, and turns opening it into a little show.

Write a note, tap Seal and watch it close up: a wax-sealed card, a spellbook bound by glowing runes, a dossier stamped top secret, or a treasure map rolled into a scroll. Share the sealed text in Messages, Mail or anywhere else. Your friend pastes it into Cipherkin and watches it open.

HOW IT WORKS
• Write and seal a note, then copy or share the sealed text.
• The recipient taps Paste in Cipherkin to open it.
• Opening every message, in every theme, is always free.

FREE
• Classic Cipher: a cream card that scrambles into cipher and is sealed with wax.
• Free notes use a password built into the app, so anyone with Cipherkin can open them. They're for fun, not for secrets.

CIPHERKIN FULL: ONE-TIME PURCHASE
• Arcane Runes, Secret Agent and Pirate's Code, plus future themes as they arrive in updates.
• Set your own password, so only people you tell can open your note. Give them the password separately, in person or by a call.
• Preview every theme before you decide.

NO ACCOUNTS, NO TRACKING
• No account, no ads, no analytics, no servers.
• Works offline. Sealing and opening happen on your device.
• Cipherkin doesn't save your notes, passwords or history, and reads the clipboard only when you tap Paste.
• Notes are sealed with AES-256-GCM, with keys derived from the password by Argon2id. Short or common passwords can be guessed by someone who has the sealed text, so use a longer one for anything that matters.

ACCESSIBLE
• VoiceOver, large text, Reduce Motion, and a Skip button on every animation.
