Privacy Policy

Last Updated: March 20, 2026

Welcome to mhtmltopdf.online (mhtmltopdf.online). We believe document privacy is a fundamental right. When converting web archives, your files may contain confidential financial dossiers, proprietary code, personal communications, or legal documents. This page describes how uploaded documents are processed for conversion.

1. Document Conversion Processing

The cornerstone of our architecture is strict ephemeral processing:

  • Server Processing: Uploaded files are sent to the conversion server to decode their content and generate the selected output. Rendering uses a separate browser instance that closes after conversion.
  • No Application File Store: The application does not save uploads or outputs to a database or persistent file store. Chromium may use temporary browser-profile data while rendering.
  • Request Lifecycle: Output is returned with no-store caching headers. The rendering browser is closed after processing. There is no scheduled 60-minute deletion service.
  • Zero Content Inspection: We do not inspect, parse for advertising keywords, index, or retain any data from your documents. We do not use your documents to train machine learning models.

2. Information We Collect

2.1 Document Data

Document content is processed for the conversion request. Your browser keeps the generated download available in the current tab until reset or navigation. Downloaded files remain on your device until you delete them.

2.2 Contact Form Inquiries

If you reach out to our team via our Contact Us page, we collect only the information you voluntarily supply — your name, email address, and inquiry details. This information is used strictly to respond to your support request and is never shared with third parties.

2.3 System Telemetry & Diagnostic Logs

To maintain high availability, prevent DDoS attacks, and optimize system speed, our web servers collect standard technical diagnostics:

  • Anonymized IP addresses (truncated where applicable)
  • Browser user-agent and operating system details
  • HTTP request status codes and timestamp of access
  • Aggregated performance metrics (conversion latency, error rates)

These diagnostic logs are kept strictly for infrastructure defense and reliability analysis, and cannot be linked to individual document contents.

3. Local Storage and Client Preferences

mhtmltopdf.online does not use invasive tracking cookies. We utilize client-side browser localStoragesolely for your convenience:

  • Theme Preference: Storing your choice between signature luxury Dark Mode and crisp Light Mode.
  • Zero Tracking Cookies: We do not deploy third-party advertising cookies or cross-site tracking beacons.

4. Third-Party Services

We do not sell, rent, or trade your data to third-party data aggregators or ad networks. In operating our site, we may utilize secure cloud infrastructure providers and privacy-focused CDN edge networks subject to strict confidentiality agreements and data protection standards (such as GDPR and CCPA/CPRA).

5. Data Security Measures

We enforce comprehensive technical protections across the document synthesis lifecycle:

  • TLS 1.3 Transport Encryption: All data transmitted between your browser and our servers is secured via modern TLS encryption.
  • Restricted Uploaded Content: Scripts and embedded frames are removed from uploaded HTML and archives. The viewer uses a sandboxed iframe, and upload rendering blocks external network resources.
  • Resource Limits: Conversion requests have file-size and rendering limits. Live URL fetching rejects private and local network addresses.

6. Children's Online Privacy

mhtmltopdf.online is a general audience document utility. We do not knowingly collect or solicit personal data from children under 13 years of age.

7. Your Privacy Rights

Under global privacy frameworks (including GDPR, UK GDPR, and California CCPA/CPRA), you have the right to request information regarding your personal data. The application does not maintain a database or file store of uploaded documents or generated outputs. For any inquiries regarding support communications, you may contact our data protection team at any time.

8. Updates to This Privacy Policy

We may periodically update this Privacy Policy to reflect architectural improvements or regulatory obligations. Any revisions will be posted to this page with an updated "Last Updated" date.
