Privacy Policy

Last updated: June 28, 2026

This Privacy Policy describes how the Network Request Sniffer Chrome extension (“Extension”, “we”, “us”) handles information when you use our product. The Extension is published by valkos.by.

1. Summary

Network Request Sniffer captures network request metadata from websites you visit (such as URLs, HTTP methods, headers, status codes, and response bodies when available). All processing happens locally in your browser. We do not transmit captured data to our servers because we do not operate collection servers for this Extension.

2. Information the Extension may access

When you use the Extension, it may access and store locally:

• Request URLs, HTTP methods, and timestamps
• Request and response headers
• Response body content when technically available (e.g. JSON responses)
• Tab identifiers needed to associate requests with the active browser tab
• Video stream URLs (HLS, DASH, and related formats)

Because the Extension monitors network activity on pages you open, captured data may include personal or sensitive information that those websites send or receive (for example, account tokens in URLs or API responses). You are responsible for handling exported files securely.

3. How we use information

Information is used only to provide Extension functionality:

• Display captured requests in the Extension popup and DevTools panel
• Filter, search, copy, and export data at your request
• Temporarily store recent requests in browser memory during your session

We do not use captured data for advertising, profiling, or sale to third parties.

4. Data storage and retention

Captured requests are kept in the Extension’s in-memory storage while the browser is running. Data may be cleared when you click “Clear” in the Extension, when the browser restarts, or when the Extension is removed. Exported files are saved to your device through your browser’s download mechanism and are not controlled by us after download.

5. Data sharing

We do not sell, rent, or share your data with third parties. The Extension does not send captured network data to valkos.by or any other remote service operated by us.

Data you export or copy may be shared by you intentionally (for example, by sending a HAR file to a colleague). That sharing is under your control.

6. Permissions

The Extension requests the following Chrome permissions:

• webRequest — to observe network requests and responses
• storage — to keep Extension settings and session data locally
• downloads — to save exported JSON, CSV, and HAR files
• tabs — to associate requests with browser tabs
• clipboardWrite — to copy URLs at your request
• host_permissions (<all_urls>) — to monitor requests on websites you visit

These permissions are required for core functionality and are not used for unrelated purposes.

7. Children’s privacy

The Extension is not directed to children under 13 (or the minimum age required in your jurisdiction). We do not knowingly collect personal information from children.

8. Your choices

• Pause recording using the Extension controls
• Clear captured requests at any time
• Uninstall the Extension to stop all data capture
• Review and restrict which websites you visit while recording is enabled

9. Changes to this policy

We may update this Privacy Policy from time to time. The “Last updated” date at the top will reflect the latest version. Continued use of the Extension after changes means you accept the updated policy.
