Privacy-first browser engineering for local data processing.

Utilvo develops browser-based software and research focused on client-side computation, privacy-preserving architectures, WebAssembly, and secure browser runtimes.

Our work explores how data-intensive applications can perform processing locally on the user's device while minimizing unnecessary server-side data exposure.

A technical study of browser-based local processing architectures using WebAssembly, Web Workers, and client-side execution.

The research includes implementation materials, benchmark methodology, and reproducibility resources.

Utilvo projects generally follow these principles:

• Client-side processing — perform computation locally whenever practical.
• Data minimization — avoid sending user data to servers when server processing is unnecessary.
• Reproducibility — document implementations, benchmarks, and methodology.
• Explicit security boundaries — document what the architecture protects and what it does not.
• Open technical documentation — make implementation decisions inspectable where possible.

• PDF Tools — Browser-based PDF processing designed around local execution.

• Calculators — Browser-based mathematical and engineering calculators.

• Unit Converter — Physical and SI unit conversion utilities.

Public repositories contain implementations, experiments, benchmarks, and supporting research materials.

Repositories are published when they contain sufficient implementation or documentation to be independently inspected or reproduced.

Privacy claims are evaluated within an explicit technical threat model.

Client-side processing can prevent a server from receiving the processed source data, but it does not by itself protect against a compromised device, malicious browser extensions, compromised dependencies, or malicious code executed in the browser environment.

Security documentation and project-specific limitations are provided in each repository.
