Privacy Policy — BJJ Deal Watcher for BJJHQ

Privacy information for the Chrome/Chromium extension and Firefox add-on.

Last updated: September 10, 2026Created by Max Luong

01Overview

BJJ Deal Watcher for BJJHQ is designed to help users view current Brazilian Jiu-Jitsu gear, apparel, training equipment, and other deal information, and to receive optional deal alerts.

The extension is designed to keep user preferences and deal history within the user's browser.

02Information stored locally

The extension may store information locally in your browser, including:

  • Selected store/country region
  • Interface language
  • Theme preference
  • Notification preferences
  • Selected product interests
  • Optional price limits
  • Optional watch terms
  • Saved size preferences
  • Locally observed deal history
  • Current/cached deal information
  • Deal expiration information used for background refreshes

This information is used to provide the extension's features and preferences.

Normal extension preference and history data is intended to remain in browser extension storage rather than being sent to Lu-ong.com. The extension does still make ordinary web requests in order to obtain public deal information (see Website access below).

03No account required

  • No Lu-ong.com account is required to use the extension
  • You do not need to create a profile with the developer
  • The extension does not require your name, address, phone number, or payment information

04Website access

The extension accesses publicly available BJJHQ pages and resources to obtain information necessary for features such as the current deal, product title, price, shipping information, product image, deal countdown, description, specifications, and size-guide information when available.

When the extension requests information from BJJHQ, those requests are made to BJJHQ or its supporting web resources. As with ordinary website requests, the destination website may receive standard network information such as an IP address, browser/user-agent information, and request details according to its own privacy practices.

05Notifications and background activity

Notifications are optional and controlled by you.

  • Smart Alerts — only notify for deals matching your preferences
  • All Deals — notify whenever a new deal is detected
  • Manual / Silent — use the extension without new-deal notifications
  • Deal-ending and background refresh behavior
  • Rolling / Speed Run deal handling

If enabled, the extension can check for a new deal around the time the current deal is expected to end and can display a browser notification based on your notification preferences.

The extension does not need its popup to remain open for supported browser background features to operate. Browsers, device sleep, network availability, and operating-system behavior may delay background activity, so notification timing is not guaranteed.

06Data collection by the developer

  • Extension preferences are not transmitted to Lu-ong.com
  • Local deal history is not transmitted to Lu-ong.com
  • Saved watch terms are not transmitted to Lu-ong.com
  • Saved size preferences are not transmitted to Lu-ong.com
  • No advertising profile is created by the extension
  • Personal data is not sold by the extension developer

This privacy policy applies specifically to the BJJ Deal Watcher for BJJHQ browser extension. It does not describe any separate data processing performed by the Lu-ong.com website itself, which is covered by that site's own privacy information where published.

07Third-party websites

BJJHQ and other websites opened through the extension are third-party services and operate under their own terms and privacy policies.

Selecting View Deal, product links, or other external links takes you outside the extension.

08Data sharing

Locally stored extension preferences and history are not intentionally sold or shared by the developer with advertisers or data brokers.

09Data retention and removal

Locally stored extension data can remain in browser extension storage while the extension is installed.

Removing the extension or clearing its stored browser data may remove locally stored extension information, subject to the browser's own storage behavior.

10Children's privacy

The extension is not designed to collect personal information from children and does not require users to create an account or provide personal information to the developer.

11Security

The extension is designed to minimize data collection and primarily uses browser-provided extension storage for preferences and local history.

12Changes to this policy

This policy may be updated if the extension's features or data practices change. The "Last updated" date at the top of this page will identify the latest revision.
