Recipient Sovereignty

Open your verified note vault.

Notes anchored to your mobile number remain sealed behind verification. Once inside, you hold complete authority over whether signed names appear.

Enter your mobile number

First-time visits send a one-time 6-digit SMS verification code. Returning vaults with a PIN or verified email continue directly without SMS.

Zero-disclosure verification

PaperPlane never confirms whether notes exist for a number prior to SMS verification, and raw phone numbers are never stored or displayed. Standard carrier SMS rates may apply.
