Sealed

Sealed is a privacy-first messaging stationery application built around the timeless metaphor of a physical sealed letter.

Write an intentional private letter, seal it with on-device authenticated encryption, and share a unique human-typeable secret code. Your recipient enters the code to unseal and read your words.

Key Highlights:
• No accounts, logins, or phone numbers required
• No social feeds, likes, or followers
• No cloud servers storing private messages
• All encryption is performed locally on your device
• Messages are unlocked only with the secret code

Experience intentional, quiet, and truly private communication with Sealed.
