API Response Interceptor - Chrome Extension

Last Updated: November 2025

Overview

API Response Interceptor is a developer tool designed to help web developers test and debug API integrations by intercepting and modifying HTTP responses. This privacy policy explains how the extension handles your data.

        Privacy First: This extension operates entirely locally on your device.
        No data is ever transmitted to external servers, collected by the developer, or shared with third parties.
      

Data Collection

What We DO NOT Collect

Personal information (name, email, address, etc.)
Browsing history or visited URLs
Network request/response content
Authentication tokens or credentials
Usage analytics or telemetry
Any data transmitted to external servers

What Is Stored Locally

The extension stores the following data locally on your device using Chrome's storage API:

Interception Rules: The rules you create (URL patterns, response modifications, headers)
Rule Groups: Organizational groups for your rules
Extension Settings: Your preferences (theme, sort order, etc.)
Network Logs: Temporarily captured request/response data (session only, cleared on browser restart)

        Important: Network logs are stored in memory only and are automatically
        cleared when you close the browser or disable the extension. They are never persisted to disk.
      

Permissions Explained

This extension requires certain permissions to function. Here's why each permission is needed:

Permission	Purpose
`debugger`	Required to intercept network requests and return mock responses using the Chrome DevTools Protocol. This is the core functionality of the extension.
`storage`	Used to save your interception rules and settings locally. Data never leaves your device.
`activeTab`	Allows attaching the debugger to the currently active tab when you click the extension icon.
`contextMenus`	Adds a right-click "Intercept this tab" checkbox so you can toggle interception on the current tab. It only changes the extension's own state and reads no page content.
`host_permissions: <all_urls>`	Required to intercept requests on any website you're developing or testing. The extension only activates on tabs where you explicitly attach the debugger.

How Your Data Is Protected

Local Storage Only: All data remains on your device
No External Connections: The extension never connects to external servers
No Analytics: We don't track how you use the extension
User Control: You can delete all data at any time via the Import/Export settings page
Open Source: The extension code is available for inspection on GitHub

Third-Party Services

This extension does not integrate with any third-party services, analytics platforms, or advertising networks. All functionality is self-contained.

Data Retention

Rules and Settings: Stored until you manually delete them or uninstall the extension
Network Logs: Stored in memory only; cleared when browser closes or debugger detaches

To delete all extension data, use the "Clear All Rules" option in the Import/Export settings, or uninstall the extension.

Children's Privacy

This extension is a developer tool and is not intended for use by children under 13. We do not knowingly collect any information from children.

Changes to This Policy

We may update this privacy policy from time to time. Any changes will be reflected on this page with an updated "Last Updated" date. Continued use of the extension after changes constitutes acceptance of the new policy.
