Confidential files that self-destruct after review

Share high-stakes M&A memos, litigation discovery, and executive strategies with progressive cryptographic decay that renders exfiltrated files unreadable

Files Protected

Exfiltration Rate

Avg Time to Decay

Enterprise Trust Score

Built for negotiations where leaks are not an option

Stop trusting polite NDAs. Enforce cryptographic physics on every document you send

Progressive Byte Degradation

Render repeated unauthorized opens illegible

Cryptographic noise is injected into document layers upon each authenticated read session

Ensures sensitive numbers cannot be systematically scraped over extended timeframes

Biometric Steganography

Trace physical leaks back to the exact source

Embeds imperceptible viewer signatures into the visual display layer

Survives high-resolution external camera screenshots and social media re-compression

FAQ

Will this corrupt my original files on my own computer? +

No. Your master assets remain intact on your local machine. Cinder only compiles and degrades the encrypted client-side viewing instances.

Do my clients need to install special software or extensions to open files? +

No. Cinder renders directly within standard secure web browsers using WebAssembly and WebCrypto enclaves.

Can a recipient bypass decay by printing the page to PDF? +

Print functions and virtual PDF drivers are cryptographically blocked and trigger immediate file termination.
