Privacy by Architecture

About Pexlii & Engineering Charter

Pexlii is built to eliminate unnecessary cloud intermediaries. Traditional web utilities stream private documents, credentials, and image files to remote servers. We invert that model: wherever modern browser APIs permit, execution occurs 100% locally on your machine.

Local Engine Isolation

In-Browser tools use WebAssembly, Web Crypto, and Canvas so sensitive payloads never leave memory.

Fast Local Execution

Eliminating remote upload pipes and queuing means instant conversions, calculations, and diagnostics.

Zero Account Barriers

Unrestricted access with zero accounts, zero tracking pixels, and zero artificial limits.

Engineering Standards

Cryptographic Entropy: Password and random generation rely on window.crypto.getRandomValues for hardware entropy.
High-Resolution Timing: Timers and stopwatches leverage performance.now() timestamps.
Architectural Transparency: Every utility discloses its processing model with clear privacy indicators.
Accessible HTML5: Keyboard navigation, ARIA landmarks, and contrast compliance.
