Console Catcher - Privacy Policy

Last updated: April 21, 2026

Overview

Console Catcher is a Chrome extension that captures and displays JavaScript console output (logs, warnings, errors) in a popup panel. Your privacy is important, and this extension is designed to keep all data local to your browser.

Data Collection

Console Catcher does not collect, store, transmit, or share any data externally. Specifically:

• No personal information is collected.
• No browsing history is recorded.
• No console output data leaves your browser.
• No analytics or tracking scripts are used.
• No cookies are set by the extension.
• No data is sent to external servers.

How It Works

Console Catcher uses a content script to intercept JavaScript console method calls (log, warn, error, info, debug) on web pages. The extension reads only the arguments passed to console.* calls and unhandled-error events. It does not read page content, form data, cookies, request/response bodies, or any other data from the pages you visit. Captured log entries are stored temporarily in chrome.storage.local on your device. Log data is automatically cleared when a tab navigates to a new page or when the tab is closed. At most 500 entries are stored per tab. No data is persisted beyond the current browsing session for each tab.

Permissions

The extension requests the following permissions:

• storage — Used for temporarily storing captured console log entries and user preferences (such as capture on/off state) locally on your device.
• activeTab — Used by the popup's "Run Test" button to identify the currently active tab and inject a set of four sample console.* calls so you can verify capture is working.
• scripting — Used by the same "Run Test" button to call chrome.scripting.executeScript with a hard-coded inline function. No remote code, no dynamic code, and no user-supplied strings are ever executed.
• Host access to all URLs (via content scripts) — Required to observe console.* calls on any website you are debugging. The extension can be used on any site a developer needs to inspect, so limiting the host list would break the core feature. Content scripts read only the arguments of console.* calls and unhandled errors; no other page data is accessed.

Third-Party Services

Console Catcher does not use any third-party services, APIs, or SDKs.

Changes to This Policy

If this privacy policy is updated, the changes will be posted here with a revised date. The extension will continue to operate on the principle of zero external data collection.
