Privacy Policy

ComUtil.com ('we', 'us', or 'our') operates the ComUtil.com website. This Privacy Policy explains how we collect, use, and protect information when you use our developer tools and services.

By using ComUtil.com, you agree to the collection and use of information in accordance with this policy.

Automatically Collected Information

When you visit our website, we may automatically collect certain information about your device and usage:

• IP address (for network-related tools like IP lookup)
• Browser type and version
• Pages visited and time spent
• Referring website

User-Provided Data

Browser-local workflows such as Base64 encoder, URL encoder, and JSON editor can run without sending the text to ComUtil first.

Other tools, including Hash generator, JWT decoder, prompt toolkit, and structured output validation, submit request data to ComUtil for processing.

For lookup tools such as IP lookup and Domain WHOIS, ComUtil processes the query data so it can retrieve registry, network, or certificate information for the immediate request.

Recent domain lookup history is stored only in this browser on this device and can be cleared from the domain lookup page.
