1. Introduction

iTextMaster ("we", "our", or "us") is committed to protecting your privacy. This Privacy Policy explains how we handle your information when you use our PDF tools.

2. How Our Service Works

iTextMaster is local-first. Most PDF tools run in your browser, while a small number of tools require server-side processing and disclose that clearly. This means:

  • Most file-based PDF processing happens directly in your web browser
  • Server-side tools submit only the information needed for that conversion, such as a public URL for Webpage to PDF
  • Localhost, private network, metadata, and internal-only URLs are blocked for server-side webpage conversion
  • Generated results are returned to your browser and are not intentionally stored by the tool

3. Information We Collect

3.1 Your Files

We do not collect your files for local browser tools. When a tool requires server-side processing, the page explains that processing before submission and the generated result is returned to your browser.

3.2 Usage Data

We may collect anonymous usage statistics to improve our service:

  • Which tools are most popular
  • General geographic region (country level)
  • Browser type and version
  • Device type (desktop, mobile, tablet)

This data is aggregated and anonymized — it cannot be used to identify you.

4. Local Storage

iTextMaster may use your browser's local storage to:

  • Remember your language preference
  • Store your recent tool history
  • Save work-in-progress for interrupted sessions

This data is stored only on your device and is never transmitted to us.

5. Cookies

We use essential storage and optional analytics cookies:

  • Essential cookies: Required for the website to function properly
  • Preference cookies: Remember settings like language preference
  • Analytics cookies: Enabled only after you explicitly allow anonymous analytics

Google Analytics Consent Mode defaults analytics storage to denied. We do not use advertising cookies.

6. Third-Party Services

iTextMaster does not share file contents with analytics or advertising providers. With consent, Google Analytics receives aggregate page and interaction events. We do not use:

  • Analytics event parameters containing file names, document contents, email addresses, API keys, or payment-page data
  • Advertising networks
  • Social media tracking pixels
  • Third-party file processing services for uploaded documents

7. Your Rights

You can decline analytics, clear cookies and local storage, or change browser privacy settings at any time. Contact us if you have a privacy request concerning account or analytics data.

8. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page and updating the "Last updated" date.
