Privacy Policy

Effective Date: January 1, 2024  |  Last Updated: October 9, 2026

1. Introduction

Welcome to OpenToolFactory ("we," "our," or "us"), available at https://opentoolfactory.com. We are committed to respecting and protecting your privacy. This Privacy Policy details our operational practices, how we handle user data, our 100% client-side privacy architecture, and our use of third-party services including Google AdSense.

2. Our Core Principle: 100% Client-Side Processing

Zero Server Upload Architecture: All files processed through our utilities (including image compressors, PDF mergers, converters, Base64 tools, SVG modifiers, and e-invoicing suites) are processed locally inside your web browser using HTML5 APIs, WebAssembly, and client-side JavaScript.

Your images, PDF files, text snippets, and document contents never leave your device. We do not transmit, inspect, store, or possess copies of any files or content you process with our tools. When you close your browser tab, all temporary memory state is discarded immediately by your browser sandbox.

3. Information We Collect

3.1 Voluntary Communications

If you contact us via our contact form or email (for feedback, feature requests, or technical support), we collect your name, email address, and message contents solely to communicate with you and address your inquiry.

3.2 Automated Technical & Aggregate Data

Like standard websites, our hosting provider (Vercel) and analytics services (Google Analytics 4) may log non-personally identifiable technical information, such as:

  • Browser type, language, and operating system
  • Referring website and exit pages
  • Approximate geographic region (country/city level, non-precise)
  • Date and timestamp of visits and aggregate page interaction metrics

4. Cookies, Web Beacons, and Tracking Technologies
