100% Client-Side Privacy Guarantee

Privacy Policy

Effective Date: January 1, 2026 • Last updated: September 2026

The Zero-Server Guarantee

At htmlformater.com, your source code privacy is our paramount engineering commitment. All HTML formatting, beautification, tag stripping, and vector PDF compilation take place 100% locally inside your web browser using client-side Web Workers. Your markup, scripts, and private data are never sent, saved, or inspected by our servers.

1. Information We Do Not Collect

When you paste, type, or upload HTML files into our workbench:

  • We do not transmit your source code to any cloud service, remote server, or third-party API.
  • We do not log, cache, or store HTML snippets, email backups, or file contents.
  • We do not collect personally identifiable information (PII) unless you explicitly contact us via email.

2. Client-Side Web Workers & Sandboxing

Our formatting algorithms run within isolated browser Web Worker threads. These background threads execute locally on your device's processor:

  • Zero Outbound Requests: Web Workers are strictly prohibited from making network calls with your code.
  • Iframe Sandboxing: The live HTML viewer isolates DOM preview rendering using strict sandbox attributes to prevent cross-origin script injection.

3. Local Storage Preferences

To maintain your user experience across browser sessions, we may store non-sensitive configuration settings in your browser's local storage (localStorage), such as:

  • Indentation preference (2 spaces, 4 spaces, or tab)
  • Line wrap settings (80, 100, 120 chars, or no wrap)
  • Interface language preference

You can clear these preferences at any time by clearing your browser's site data or cache.

4. CDN Infrastructure & Edge Security

Static web assets (HTML, CSS, JavaScript) are served via globally distributed Content Delivery Networks (such as Cloudflare). Standard anonymous technical metadata (such as IP addresses and user-agent strings) may be processed transiently at the network edge solely for DDoS mitigation, bot protection, and cache routing.

5. GDPR and CCPA Compliance

Because htmlformater.com does not collect, store, or sell personal data or uploaded source code, our architecture is compliant by design with the General Data Protection Regulation (GDPR) and the California Consumer Privacy Act (CCPA).
