Privacy Policy

Effective date: 2025-05-01

1. Introduction

Load Time Tracker ("the Extension") is a Chrome browser extension designed to help developers and QA teams measure, record, and visualize page-load performance in real time. This policy explains what data the Extension collects, how it is used, where it is stored, and your rights and controls.

2. Data Collected

The Extension collects and stores the following information locally in your browser's storage:

Tracked domains: the list of hostnames you explicitly add via the "＋" button.
Load events:
- timestamp: the millisecond-precision moment when a tracked page completes loading.
- loadTime: the duration (in milliseconds) between navigation start and the page's load event, obtained via the Performance API or a timestamp fallback.
In-flight timing: transient start timestamps used to drive the live badge timer while a page is loading.
Favicons: URLs scraped from each page's <link rel="icon"> tags for display in the popup.

3. Purpose of Collection

We use this data solely to:

Display a live badge timer on your toolbar icon while a tracked page loads.
Persist each page's final loadTime and timestamp when loading completes.
Compute and display sliding-window aggregates: total load time over the last hour, day, week, and month.
Show per-site statistics in the popup, including last load duration, average load time, and reload count.
Prune logs older than 30 days automatically to keep your data fresh and storage usage minimal.
Render each site's favicon for easy recognition.

4. Storage & Retention

All data is stored in chrome.storage.local under your profile. No data leaves your device. Records older than 30 days are automatically pruned by the Extension on each new load event.

5. No External Sharing

We do not transmit, share, sell, or analyze any of your data on remote servers. There is no external backend or analytics service. All processing and storage occur entirely on your local machine.

6. Security Practices

All code runs locally under the Chrome Extension framework—no remote code execution.
The Extension requests only the minimum necessary permissions ( storage, webNavigation, activeTab, scripting, and host access to <all_urls>).
Data isolation: information is kept within your Chrome profile and cannot be accessed by other profiles or users.

7. Your Controls & Rights

Manage tracked sites: add or remove domains at any time via the popup UI.
Clear data for a site: clicking "×" next to a domain removes its logs, in-flight entry, and favicon.
Uninstall: removing the Extension clears chrome.storage.local entirely.
Inspect storage: browse to DevTools → Application → Storage → Extensions to view raw data.

8. Changes to This Policy

We may update this policy to reflect new features or legal requirements. Any changes will be posted here with an updated Effective date. Continued use of the Extension after updates implies your acceptance.
