The hour
It stays sealed until the day and time you set. A guest sees the seal, not the words.
Sealed letters
Write it now. The words wait.
Open Sealed
/open/9f3a…
Sealed, then the words.
It stays sealed until the day and time you set. A guest sees the seal, not the words.
When the hour comes, it can be read, and only for as long as you allow. Then it closes.
You can still read it after the letter has closed.
The seal is a clock. The letter is stored as plain text and is not encrypted.
