Privacy Policy

Last updated: January 24, 2026

Privacy Summary

TL;DR: TechUtility.io is designed with privacy as a core principle. All tools run locally in your browser. We don't collect, store, or transmit your personal data to our servers. Your files, text, passwords, and other inputs never leave your device.

Information We Do NOT Collect

TechUtility.io is built on the principle of minimal data collection. We do NOT collect:

  • Personal information (name, email, phone number)
  • Account credentials or passwords you input into our tools
  • Files or documents you process using our tools
  • Text, images, or any other content you work with
  • IP addresses for tracking purposes
  • Browsing history or tool usage patterns
  • Device fingerprints or unique identifiers

How Our Tools Work

All tools on TechUtility.io are designed to run entirely in your web browser using JavaScript. This is called "client-side processing" and means:

  • Your data is processed locally on your device
  • No data is sent to our servers for processing
  • Tools work even when you're offline (after initial page load)
  • Your sensitive information never leaves your computer

Exception: Some tools require external API calls for functionality that cannot be performed locally (e.g., IP geolocation, DNS lookups). In these cases:

  • Only the minimum required data is sent (e.g., an IP address for geolocation)
  • We use reputable, free public APIs
  • These tools are clearly marked when external calls are made
  • No personal or identifying information is transmitted

Local Storage & Cookies

TechUtility.io uses your browser's localStorage to store:

  • Theme preference: Light/dark mode setting
  • Favorite tools: Tools you've marked as favorites
  • Recent tools: Recently used tools for quick access
  • Tool settings: Your preferences for individual tools

This data is stored only in your browser and is never sent to our servers. You can clear this data at any time by clearing your browser's local storage or using your browser's "Clear Site Data" feature.

We do not use tracking cookies, advertising cookies, or any third-party cookies.

Third-Party Services

Some tools use third-party APIs for specific functionality:

  • IP Geolocation: Uses public APIs to look up IP address locations
  • DNS Lookups: Uses Google DNS and Cloudflare DNS over HTTPS
  • Password Breach Check: Uses Have I Been Pwned API with k-anonymity
  • MAC Vendor Lookup: Fetches OUI database from public sources
  • WHOIS/RDAP: Queries public RDAP servers for domain information

These services have their own privacy policies. We encourage you to review them if you use these specific tools.

Hosting

TechUtility.io is hosted on Cloudflare Pages. Cloudflare may collect standard web server logs (IP addresses, browser type, access times) for security and performance purposes. This is standard web hosting practice and is governed by Cloudflare's privacy policy.

Children's Privacy

TechUtility.io does not knowingly collect any personal information from children under the age of 13. Since we don't collect personal information from any users, this applies to all visitors regardless of age.

Changes to This Policy

We may update this privacy policy from time to time. Any changes will be posted on this page with an updated "Last updated" date. We encourage you to review this policy periodically.
