What LogLens does

LogLens is a Chrome extension that captures console logs, JavaScript errors, network requests, and WebSocket frames from web pages you choose to monitor. It is a local developer tool — no accounts, no servers, no analytics.

Data we do NOT collect

• No personal information (name, email, IP address)
• No browsing history
• No page content is sent anywhere
• No usage analytics or telemetry
• No credentials or authentication data

Data stored locally

LogLens stores the following data only on your device, using Chrome's built-in storage APIs:

• UI preferences — theme (light/dark) and language (English/Vietnamese), saved via chrome.storage.local
• Extension settings — alert patterns, slow-request threshold, spike window, and other toggles, saved via chrome.storage.local
• Captured log sessions — console events, network events, and error data from pages you explicitly choose to monitor, saved via IndexedDB in your browser

This data never leaves your device. You can clear it at any time using the "Clear all storage" button inside the extension.

Permissions used and why

• debugger — to attach to browser tabs via Chrome DevTools Protocol and capture runtime events
• storage / unlimitedStorage — to save preferences and log sessions locally
• activeTab — to read the current tab's URL for display and export file naming
• tabs — to detect when a monitored tab is closed and clean up the session
• notifications — to show local alerts when a pattern matches or an error spike occurs
• <all_urls> — required by the debugger API to attach to any URL the developer chooses to inspect

Third parties

LogLens does not communicate with any third-party servers. No data is sold, shared, or transferred to any external party under any circumstances.

Remote code

LogLens does not load or execute any remote code. All JavaScript is bundled inside the extension package.
