Each note is deleted 7 days after its creation, even if it has not yet been read. The system allows the generation of a note that can only be viewed once. Immediately after its creation, the note and any attached images are encrypted before being transmitted to the server. The decryption key is never known to the server. This ensures that no one, including the server administrators, has access to the decrypted content of the note.
When the provided link is accessed and the display button is clicked, the note is retrieved and immediately deleted from the server. Since the decryption key is only known to the user's original browser, only that browser can decrypt and display the note. No cookies are used on this page. If the provided link is lost, there is absolutely no way to retrieve or decrypt the note. If the key (in the link after the #) has been altered, the message will be immediately deleted upon access, even if it cannot be displayed due to the incorrect key.
