Privacy Policy — NOC Toolkit

Last updated: September 6, 2026

Overview

NOC Toolkit (“the extension”) is a browser tool for IT and network diagnostics: IP lookup, DNS resolution, MAC vendor lookup, blacklist (RBL) checking, and subnet calculation. This policy explains what data the extension does and does not collect.

What the extension does NOT do

• It does not collect, transmit, or store any personal data on our servers — we don’t operate any servers.
• It does not track your browsing activity.
• It does not use analytics, telemetry, or advertising SDKs of any kind.
• It does not access the content of the web pages you visit. The extension only runs inside its own popup window.

  What data is processed, and how

When you use a feature, the extension sends a request directly from your browser to a third-party lookup service to fetch the result you asked for:

Feature	Data sent	Sent to
IP Lookup	The IP address you typed, or a request for your own public IP	ipwho.is
DNS Lookup	The domain name you typed	Google Public DNS (dns.google)
MAC Vendor Lookup	The MAC address you typed	macvendors.com
Blacklist (RBL) Check	The IP address you typed, reformatted as a DNS query	Google Public DNS (dns.google) — queried against public blacklist zones (Spamhaus, SpamCop, Barracuda, SORBS)
Subnet Calculator	Nothing — this runs entirely on your device with no network request	—

These requests go directly from your browser to the third-party service named above; NOC Toolkit itself never sees or stores this data. Each service’s own privacy policy governs how they handle that request (typically standard server logs, e.g. IP address and timestamp, consistent with normal web server operation).

Local storage

The extension uses your browser’s local storage (via the chrome.storage API) to remember two small preferences on your own device only:

• which tab (IP / DNS / Subnet / MAC / RBL) you last had open
• which DNS record type you last selected This data never leaves your device and is not accessible to us or to any third party.

Permissions

The extension requests:

• storage — to remember the preferences described above
• Host access to ipwho.is, dns.google, and api.macvendors.com — the three lookup services described above (the blacklist check reuses the existing dns.google access; no additional host permission was needed for that feature) No other permissions are requested. The extension cannot read, modify, or access any other website you visit.

Changes to this policy

If this policy changes, the “Last updated” date above will be revised. Material changes will also be reflected in the extension’s Chrome Web Store listing.
