TagProof — Analytics & Pixel QA Inspector

Last updated: June 2026

TagProof is a Chrome extension built by PixelForgeHub (Yogesh Nichal). This policy explains what data the extension touches and where it goes.

Summary

TagProof is built privacy-first. Tag inspection runs entirely on your device in memory. No page content or browsing history is ever collected, stored, or transmitted. The only network connections TagProof ever makes are a one-time license verification with Lemon Squeezy, and an optional, user-configured sync to your own Cloudflare Worker for Pro monitoring.

What TagProof Reads & Modifies

To inspect and validate your analytics and advertising pixels, TagProof runs local content scripts. These scripts:

Observe the network requests made by the page itself to identify analytics and ad tag beacons (GA4, GTM, Google Ads, Meta Pixel, Bing UET, LinkedIn, TikTok, Pinterest, etc.).
Read the browser's local Resource Timing API to recover beacons that fired on page load.
Never read, store, or transmit the content of the pages you visit.
Do not track your browsing history or run on any website until you explicitly click the toolbar icon.

What We Store Locally

The following data is saved inside Chrome's local extension storage (chrome.storage.local) on your device only:

Your license key and activation state.
Your preferences.
(Pro) Per-site baselines (a simple list of expected tag and event names, containing no page content).
(Pro) Your monitoring config (your Worker URL, Slack/Discord webhook, and alert email).

All stored data is deleted when you uninstall the extension. None of it is synced to Google or PixelForgeHub.

Data Sent Over the Network

TagProof makes at most two network calls, both of which are direct and under your control:

api.lemonsqueezy.com:When you enter a license key in the settings and click “Activate”, the background service worker sends the key to Lemon Squeezy to verify its validity. No PixelForgeHub servers are involved.
Your own Worker (Pro Only): Only if you choose to enable Pro monitoring and enter your own Worker URL (*.workers.dev), TagProof sends the page URL you chose to monitor, its expected event baseline, and your alert webhooks/email to your own Cloudflare account.

Permissions Explained

activeTab: Grants permission to inspect the active tab only when you click the toolbar icon. TagProof does not have background access to your websites.
scripting: Required to inject the local inspection scripts on demand under the activeTab grant.
storage: Required to save your preferences, license, baselines, and monitoring config locally on your device.

TagProof declares no host_permissions, no webRequest, no background content scripts, and loads no remote code.
