100 words: NO SUS keeps your files on every screen and lets you choose how you send them. The app has two tabs. Chat is your own chat, stored in your Google Drive. Open your domain on a borrowed computer, scan its QR with the app and approve. That screen never gets your Google password. Send has three ways. One open: encrypted on your device, opened once, then deleted. Watermarked: each viewer's typed email is stamped across the document. Traceable copies: each reader gets a slightly reworded copy of a note, so leaked text shows whose copy it was. The native app is Android.
