Encrypt, track, and revoke emails and files inside Gmail, Google Drive, or your own platform — protecting sensitive content from unauthorized people and AI tools, with simple access for recipients.
PPAD is a modern, low-friction DRM (Digital Rights Management) solution. Protection travels with the file itself — so you stay in control after it’s sent, forwarded, or downloaded. No matter where it ends up.
Update permissions, set expiry, or revoke access at any time — even after the file has been downloaded to someone’s laptop.
See who opened your files, when, and how much time they spent on each section. Know exactly what happened after you hit send.
Encryption, copy-paste blocking, watermarking, and screenshot deterrence keep sensitive content away from unauthorized users and AI tools — even after files are downloaded.
PPAD works in different ways depending on how your team shares sensitive information.
For teams that share sensitive information through Google Workspace and need control, compliance, and audit visibility without leaving familiar tools.
For developers, SaaS platforms, and portal builders that need persistent file protection, revocation, and tracking built into their existing architecture.

Once a file is downloaded or forwarded, there's nothing stopping a recipient from feeding it into an AI tool. PPAD makes that significantly harder.
Encrypted files are unreadable to AI. Protected files can't be indexed or ingested by AI systems without authorization.
Copy-paste extraction blocked. Recipients can't lift text from protected files into AI prompts.
Screenshots made harder. ScreenShield limits how much content is visible at once and blocks screen capture attempts.
Three steps. No new platform. Simple access for recipients.
Encrypt emails and attachments in Gmail with a single toggle. Right-click to convert files in Google Drive. Or use the API to protect files programmatically inside your own product.
Recipients access protected content securely — no desktop software required, no complicated logins. Simple access for the people you share with.
Track who opened what and when. Update permissions. Apply watermarks. Revoke access at any time — even after the file has been downloaded and saved on someone else’s device.
Traditional DRM protects files, but makes recipients jump through hoops to open them. PPAD gives you the same level of control — without the friction.

Persistent Protection After Download (PPAD) is a modern approach to Digital Rights Management that helps you keep control over files after they are downloaded. PPAD files follow the rules you set, such as view-only access, expiration dates, or the ability to revoke access.
Digital Rights Management (DRM) enables you to set and control copyright protection and data privacy for your intellectual property, such as market research, eBooks, training materials, PDFs modules and reports. DRM protection enables you to prevent your digital files from unauthorized redistribution and restrict how your recipients can copy content.
