Brickfact extension privacy notice
Scope
This notice describes the Brickfact Chrome extension. It compares LEGO set prices and shows recorded retail price history without a Brickfact account. The Brickfact website, app and shop websites have their own privacy information when you choose to visit them.
Page access when you open the extension
Only when you open the extension, it reads limited product metadata, product/page titles and the URL path to suggest set numbers. Tracking query parameters are ignored. It does not read form values, passwords, cookies, full page text or browsing history. Only candidate set numbers are returned locally; the visited-page URL and page text are not sent to Brickfact. Product detection does not run in the background.
Searches and price requests
When you submit a search or confirm a set, that search text or set number and your delivery market are sent to Brickfact over HTTPS to retrieve prices and history. Normal connection information, including IP address and browser user agent, reaches the service. A short-lived set token is used in memory only and is not saved or logged by the extension. Requests omit cookies and referrers and refuse redirects. Temporary failures may be retried once; a rejected token may be renewed once.
Storage and deletion
Only country and language preferences are saved in Chrome local extension storage on this device. You can change them in the extension; uninstalling it removes this storage. Searches, page URLs, offer prices, tokens, collections and watchlists are not stored by the extension. The service may retain normal infrastructure logs under the website privacy policy linked below; this extension does not change server-side retention. Contact the operator below with data-access or deletion requests.
Tracking and use of data
The extension uses this information to provide the comparison you request. It contains no remote analytics, advertising pixels, background browsing tracking, alerts or notifications. It does not sell or share the information it handles for advertising or unrelated purposes. Error details contain only a fixed endpoint name, HTTP status and failure category; they are not stored or sent to analytics.
Shop links and the app
Some shop links are affiliate links. Amazon offer buttons open the matching Brickfact set page, where you can continue to Amazon with a separate click. Other shop buttons open the retailer directly. Brickfact may receive a commission on eligible purchases without an extra charge to you. A shop opens only when you choose its link. The extension does not rewrite retailer-page links or silently add attribution. Amazon is excluded from recorded history. When you open a shop or the Brickfact app download page, that website's privacy practices apply.
Permissions
activeTab provides temporary access to the active page after your action. scripting runs the small set-number detector. storage saves country and language locally. Access to https://brickfact.com/* permits fixed catalogue, offer and history reads. No cookies API, browsing-history API, notifications, proxy controls or background access to all websites is requested.

You can stop page detection by closing the popup, disable the extension in Chrome, or uninstall it. Contact the operator with questions or requests about access, correction, deletion or other applicable privacy rights. This version has no extension account to delete. For infrastructure processing and further information about your rights, see the website privacy policy below.
