Whois / DNS Peek Chrome Extension

Last Updated: May 2026

TL;DR: When you click the icon, the hostname of your current tab is sent to public DNS and RDAP services to perform the lookup. Nothing is stored, logged, or shared anywhere else.

No accounts. No analytics. No tracking. No background activity. The extension only does anything at all when you explicitly click its icon.

1. Information Collection

What Is Transmitted

When you click the extension's toolbar icon, the popup reads the hostname of your currently active tab and sends it to public DNS and RDAP services so the lookup can be performed. Specifically:

✅ The hostname of the current tab (e.g. example.com) — not the full URL, path, or query string
✅ A small number of standard DNS query types (A, AAAA, CNAME, MX, NS, TXT) and one RDAP request
✅ Your IP address, as is normal for any HTTPS request, is visible to the services you contact

What Is NOT Collected, Stored, or Transmitted

The extension does not collect, store, transmit, or process any of the following:

❌ No personal information (name, email, address, etc.)
❌ No browsing history (no list of pages you have visited, no aggregation across visits)
❌ No page content, DOM, page title, cookies, form data, or anything inside the page
❌ No full URLs — only the bare hostname is read
❌ No data from tabs other than the active one at the moment of click
❌ No analytics, usage statistics, or telemetry of any kind
❌ No device identifiers
❌ No local storage of any lookup, history, or preference (currently)

What Happens When You Use the Extension

When you click the extension icon:

The popup reads the hostname of your active tab
The popup makes a small number of HTTPS requests to the third-party services listed below, passing only the hostname
The responses (DNS records and registration data) are rendered inside the popup
When the popup closes, everything in memory is discarded
Nothing is written to disk, synced, or sent anywhere else

2. Data Usage

The extension's sole purpose is to look up DNS records and domain registration data for the current tab and display them to you. The hostname is transmitted only:

To the third-party DNS and RDAP services listed in Section 4, for the sole purpose of performing the lookup you requested
On explicit user action (clicking the toolbar icon)
Without any retention, logging, or aggregation by the extension

The extension does not share, sell, or transfer your data to any party outside of these necessary lookup requests. There is no developer-controlled server. There is no developer-controlled database.

3. Permissions Explained

The extension requires the following Chrome permissions to function:

activeTab

To identify which domain you want to look up. This permission is granted only at the moment you click the extension's toolbar icon, is scoped to the single active tab, and lets the extension read that tab's URL so it can extract the hostname. The extension does not inject scripts into the page or read page content.

Host permission: https://dns.google/*

To query Google's public DNS-over-HTTPS JSON endpoint for DNS records (A, AAAA, CNAME, MX, NS, TXT, PTR) of the active tab's hostname. Browsers do not expose a native DNS API, so a DoH service is the only available option.

Host permission: https://cloudflare-dns.com/*

Used as an automatic fallback if Google's DoH endpoint fails or returns an error. The request and the data sent are identical to those described above for Google DoH.

Host permission: https://rdap.org/*

To query the public RDAP gateway (operated by ARIN) for domain registration data: registrar, creation/update/expiration dates, status, and authoritative nameservers. RDAP is the IETF replacement for legacy whois. The gateway proxies to the correct registry RDAP server for the requested TLD.

No <all_urls>, *://*/*, or other broad host patterns are requested. No content scripts run on any host.

4. Third-Party Services

The extension makes HTTPS requests to the following public services, each of which receives only the hostname being looked up plus your IP address (as is unavoidable for any HTTPS request):

Google Public DNS — dns.google — primary DoH resolver. Privacy policy
Cloudflare DNS — cloudflare-dns.com — fallback DoH resolver, contacted only when Google fails. Privacy policy
rdap.org — public RDAP gateway operated by ARIN. ARIN privacy policy

These services are the only external endpoints the extension contacts. The extension does not use any analytics platform, advertising network, or developer-controlled API.

5. Data Security

All requests are made over HTTPS. Because the extension stores nothing and runs no developer-controlled server, there is no data at rest under the developer's control, and no data security risk on the developer's side. The extension code:

Is self-contained with no external script dependencies
Does not use remote code, eval(), or dynamic imports
Can be inspected by unpacking the extension package

6. Children's Privacy

The extension collects no personal data from anyone, including children under 13. Since no personally identifiable data is collected or stored, no special provisions for children's privacy are necessary.

7. Changes to This Policy

If the extension's data practices change, this privacy policy will be updated and the "Last Updated" date at the top will reflect the change. Material changes (for example, the addition of any new third-party endpoint or any local data storage) will be reflected here before being shipped in a new release.

8. Your Rights

Because no personal data is collected or retained by the developer:

There is no developer-held data to access, modify, or delete
There is no data to export or transfer
There are no developer-side data processing activities to opt out of

For data handling by the third-party services listed in Section 4, please refer to their respective privacy policies.

9. Contact

If you have questions about this privacy policy or the extension's practices, you can:

Review the extension package to see exactly what the extension does
Submit feedback through the Chrome Web Store

10. Compliance

This extension complies with:

Chrome Web Store Developer Program Policies
Chrome Web Store Limited Use requirements (the hostname transit is used only for the single purpose of performing the lookup the user requested)
GDPR (no personal data is collected or processed by the developer)
CCPA (no data collection or sale by the developer)

Bottom Line

Whois / DNS Peek is a small diagnostic utility. When you click its icon, it asks public DNS and RDAP services about the domain you're on and shows you the answer. Nothing is stored. Nothing is tracked. The only thing that ever leaves your browser is the hostname of the site you're currently viewing, sent to public lookup services to perform the lookup itself — the same kind of request your browser already makes to resolve DNS for any page you load.
