Sub Rosa (Under the Rose)
— An ancient idiom meaning "done in secret."

Sub Rosa separates the lock from the key. When you create a secret message, we generate a unique encryption key that is part of the link you share—we never store this key.

We only store the scrambled lockbox. Once the link is visited, the message is decrypted in your browser and the lockbox is incinerated forever.
