Privacy & Compliance

LumioPDF operates with zero-trust architecture. Your files are processed entirely in your browser's RAM using WebAssembly. We never upload, store, or see your data. Our site is a static export, meaning we don't even have a backend database to store files if we wanted to.

Designed for high-security environments. Since no data ever leaves your device, LumioPDF helps you maintain GDPR alignment and satisfies internal data governance requirements for legal and medical professionals.
