Metatag Debugger Chrome Extension
TL;DR
The extension only accesses the URL of your active tab. No browsing history, no personal data, no accounts, no analytics, no third-party tracking—ever.
1. Who We Are
Metatag Debugger is a Chrome extension developed and maintained as a personal project. The metadata analysis backend is hosted at metatag-analyzer.utilsfor.dev on Cloudflare Workers.
2. What Data the Extension Accesses
The Extension accesses only the URL and page title of the browser tab you are actively viewing. This data is used solely to initiate a metadata lookup for that URL.
The Extension does not access:
- Your browsing history beyond the current active tab's URL
- Page content, cookies, or local storage of websites you visit
- Any personally identifiable information (name, email, location, etc.)
- Passwords, credentials, or authentication data
- Financial, health, or communications data
3. How the URL Is Used
When you analyse a URL (either automatically on tab navigation or manually via the input field), the URL is sent as a query parameter to the Cloudflare Worker API:
https://metatag-analyzer.utilsfor.dev/api/metadata?url=<target-url>The Worker fetches the target page server-side, extracts its <meta> tags, and returns a structured JSON response to the Extension. The Extension then renders this response locally in the side panel.
The URL you submit is:
- Transmitted over HTTPS
- Used only to fetch and parse that page's metadata
- Not stored in any database or logging system beyond Cloudflare's standard infrastructure logs (see Section 5)
- Not sold, shared, or transferred to any third party
4. Local Storage
The Extension stores the following data locally in your browser using localStorage:
| Data | Purpose | Retention |
|---|---|---|
| Metadata analysis results | Cache to avoid redundant API calls | 5 minutes (auto-expired) |
| Theme preference (dark/light) | Remember your UI preference | Until you clear browser data |
This data never leaves your browser and is not transmitted to any server.
5. Cloudflare Infrastructure Logs
The metadata analysis API is hosted on Cloudflare Workers. As with all internet services, Cloudflare may retain standard server-side infrastructure logs (including IP addresses and request timestamps) in accordance with Cloudflare's Privacy Policy. These logs are outside our control and are not accessed or used by this Extension's developer.
6. No User Accounts
The Extension requires no account, registration, or login. No user profile or identity is created or stored.
7. No Third-Party Analytics or Tracking
The Extension does not include any analytics SDK, tracking pixel, or telemetry. No data about your usage of the Extension (e.g. which features you use, how often you use it) is collected.
8. Children's Privacy
The Extension is not directed at children under the age of 13 and does not knowingly collect any information from children.
9. Changes to This Policy
If this policy is updated, the “Last updated” date at the top of this document will be revised. Continued use of the Extension after changes are posted constitutes acceptance of the updated policy.
