Privacy Policy — Domain WHOIS Lookup

Last updated: March 16, 2026

Overview

Domain WHOIS Lookup is a browser extension that retrieves WHOIS, DNS, and SSL information for domains. Your privacy is important to us. This policy explains what data the extension accesses and how it is handled.

Data Collection

We do not collect any personal information. The only data transmitted externally is the domain name you look up, which is sent to WHOIS/DNS/SSL lookup APIs to retrieve the requested information. No personal information, browsing history, or identifying data is ever collected or transmitted.

Data Sent to Third Parties

• WHOIS / DNS / SSL Lookup APIs — The extension sends only the domain name (e.g., "example.com") to retrieve registration, DNS, and SSL data. No other data is included in these requests.

Data Storage

The extension stores your lookup history using the browser's local storage API (chrome.storage.local). This data is stored locally on your device only and never leaves your browser.

Permissions

• activeTab — Used to detect the domain of the currently active tab.
• storage — Used to save your lookup history locally.

Third-Party Services

This extension uses public WHOIS, DNS, and SSL lookup APIs solely to fetch domain information. No analytics, tracking, or advertising services are used.
