PPAD Viewer

PPAD Viewer lets authorized recipients open and view protected documents shared with them, with access controlled entirely by the sender.

Getting started is simple:

1. Tap a .ppad file from email, messaging apps, or your file explorer
2. Verify your identity with a one-time passcode (OTP)
3. If you have permission, the file opens instantly

Every document is protected by the sender's security settings, enforced automatically:

- View-only access — no downloads, printing, or forwarding
- Watermarking and screenshot protection
- Sender-controlled expiration dates
- Identity verification via secure OTP

PPAD Viewer only opens .ppad files — it does not create or protect files.
