Cryptic Send

Keep personal conversations private inside iMessage. Encrypt with your own key, auto-decrypt on tap with a key you only know and set messages to expire for added security

Send private messages inside iMessage with an extra layer of protection.

Cryptic Send helps you encrypt messages before you send them, so only someone with the same secret key can read them. It is built for private conversations, sensitive details, and moments when you want more control over who can see your message.

Why people use Cryptic Send

• Add privacy to messages sent through iMessage
• Encrypt messages with your own secret key
• Auto-load and decrypt messages when opened in the extension
• Set messages to expire for extra privacy
• Keep message content out of plain view if someone else accesses the device

How it works

1. Write your message
2. Enter your secret key
3. Send through iMessage
4. The recipient opens the message and uses the same key to decrypt it

Built for privacy

Cryptic Send is designed to protect message content before it is sent. Only the correct key can unlock the original text. For even more control, you can choose message expiration for conversations that should not stay readable forever.

Great for

• Personal conversations
• Sensitive information
• Extra privacy on shared or accessible devices
• Anyone who wants more control over message visibility

Important

Both people need the same secret key to decrypt the message.

If you want a simple way to send more private messages inside iMessage, Cryptic Send gives you that extra layer without leaving your normal messaging flow.
