Privacy Policy & Architecture

Standard web utility platforms often transmit user inputs to remote microservices for processing (such as sending base64 strings to cloud servers or uploading PDF files to remote conversion queues). PrivaUtils operates under a zero-knowledge architectural model.

// Core cryptographic isolation guarantee:
async function digestLocalBuffer(plainString: string) {
  const encoder = new TextEncoder();
  const data = encoder.encode(plainString);
  
  // Hardware-accelerated inside client context without network invocation
  const hashBuffer = await window.crypto.subtle.digest('SHA-256', data);
  const hashArray = Array.from(new Uint8Array(hashBuffer));
  return hashArray.map(b => b.toString(16).padStart(2, '0')).join('');
}

All string manipulation, regex evaluation, CSS minification, image resizing, and cryptographic derivations execute within isolated browser threads. If you disconnect your internet connection while using PrivaUtils, the processing logic continues to function offline.

When your browser connects to privautils.com to retrieve static application files (HTML, CSS, JavaScript, and WebAssembly binaries), edge hosting infrastructure and Content Delivery Networks (such as Cloudflare and Vercel) automatically record standard network transport metadata.

These server logs are collected solely for cybersecurity monitoring, firewall rule enforcement, and content delivery optimization. They are maintained separately by edge hosting providers and contain zero tool inputs, files, code snippets, or processing results.

PrivaUtils does not use first-party tracking cookies, user session cookies, or server-synced profiles. Information saved on your device remains under your direct control:

PrivaUtils is offered free of charge without subscriptions or user registration. To support server infrastructure and continuous development, we display advertisements provided by third-party ad networks, including Google AdSense.

PrivaUtils records privacy-respecting, aggregate metrics solely to detect edge outages, monitor static bundle delivery performance, and prioritize tool improvements.

We do not use session recording or heatmap tools that capture keystrokes or mouse movements inside input elements.

Because PrivaUtils does not collect or ingest personal user data on servers, our architecture adheres to privacy regulations by design:

PrivaUtils is designed for developers, technical professionals, and general audiences. We do not knowingly solicit, collect, or maintain personal information from children under the age of 13 (or under 16 in applicable European jurisdictions).

If a parent or legal guardian believes that a child has submitted personal details through our contact form, please notify us immediately. We will promptly delete that information from our communication records.

You can verify our zero-egress architecture directly using your browser developer tools:

PrivaUtils serves all web traffic strictly over encrypted HTTPS with TLS 1.3. Document streams, cryptographic keys, and hash inputs reside only in temporary memory heaps. Memory buffers are cleared when you navigate away from or close the tool.
