Send a secret once, then let it disappear.

Flowvault encrypts the note in your browser before upload. The server stores ciphertext plus expiry and view-limit metadata; it never sees the plaintext or URL-fragment key. After the final allowed view, the note is deleted from the database rather than archived.

Use it for short secrets that should not sit in Slack, email, ticket comments, or a shared document forever: temporary database credentials, API keys, recovery codes, one-time client handoffs, or a seed phrase split where the other half travels elsewhere.

If the recipient needs a durable private notebook, use a Flowvault vault instead of Encrypted Send. A send is intentionally disposable; a vault is for notes you want to reopen later, back up, or protect with a decoy password.

When a recipient opens a note, they now see a small, privacy-respecting prompt to send their own encrypted note. No tracking, no forced account, just a useful next step.
