Updated MaiPDF protection path
SendPDFOnline pages now describe MaiPDF as a two-level product family: Online Cloud Sharing creates quick browser links and QR codes, while the MaiPDF App creates protected .maipdf packages for sensitive PDFs that need App DRM controls.
Upload a PDF, share a browser link or QR code, and keep read code / modify code management.
Package the PDF in the MaiPDF App with local encryption, license rules, expiry, open limits, and revoke control.
Use protected viewer, device binding, screenshot-aware controls, watermark trace, and license management where supported.
No web page can fully stop screenshots. MaiPDF App DRM is positioned as the stronger path: reduce casual copying, bind access to identity/devices, revoke licenses, and trace leaks with visible watermark information.
