Smartbrowse for Marketplace

Privacy Policy

Effective date: April 16, 2026

Overview

Smartbrowse for Marketplace ("the extension", "we", "us") is a browser extension that helps you filter and organize Facebook Marketplace listings. We take your privacy seriously. This policy explains what data we collect, how it is used, and what we do not do.

Data we collect

Anonymous usage statistics

The extension sends limited, anonymous usage events to Google Analytics 4 (GA4) using the Measurement Protocol. These events help us understand which features are used and whether the extension is working correctly. We do not use this data for advertising, profiling, or sale to third parties. The data collected is:

  • A randomly generated client ID — a UUID created locally in your browser the first time you install the extension. It is not linked to your Google account, Facebook account, or any personally identifiable information.
  • A session ID — derived from the current timestamp and reset after 30 minutes of inactivity.
  • Event names and limited event parameters — for example, when extension pages are opened, when settings are changed, or when extension features are used. These analytics events are limited to extension interactions and DO NOT include webpage content, listing URLs, or any personally identifiable information whatsoever.

We do not collect:

  • Your name, email address, or any account credentials.
  • Marketplace listing content, URLs, prices, or seller information.
  • Your web browsing history, including lists of pages you visit, page titles, or the URLs of Marketplace listings you view.
  • IP addresses or precise location data (GA4 Measurement Protocol does not forward IP addresses to Google's reporting servers).

Extension settings and preferences

Your rules, filters, and preferences are stored locally using the Chrome browser's built-in chrome.storage.sync and chrome.storage.local APIs. chrome.storage.sync data is synchronized across your signed-in Chrome devices by Google. We have no access to this data.

How we use the data

Anonymous analytics are used solely to:

  • Understand which features are most useful so we can prioritize improvements.
  • Detect errors or unexpected usage patterns that indicate bugs.

We do not sell, rent, or share analytics data with any third party beyond Google Analytics, and we do not use it for advertising or profiling.

Third-party services

The extension uses Google Analytics 4 via the Measurement Protocol. Events are sent directly from your browser to Google's servers. Google's data collection is governed by the Google Privacy Policy.

No third-party services nor entities outside of Google receive data from the extension.

Data retention

Google Analytics retains event data for up to 14 months by default, after which it is automatically deleted. The randomly generated client ID persists in your browser's local storage until you uninstall the extension or clear the extension's storage.

Your choices

Because analytics data is anonymous and not linked to any account, there is no individual record to retrieve or delete. If you prefer not to send any usage events, you can disable or uninstall the extension to stop future analytics events from being sent.

Children's privacy

The extension is not directed at children under 13. We do not knowingly collect any information from children.

Changes to this policy

If we make material changes to this policy, we will update the effective date above and, where possible, note the change in the extension's changelog. Continued use of the extension after an update constitutes acceptance of the revised policy.
