Auction Bid Assistant does not collect, transmit, or share any personal data. Everything the extension saves stays on your device. We have no servers storing your information.
Auction Bid Assistant is developed and operated by Auctioneersvault Ltd, a company registered in the United Kingdom. For GDPR purposes, Auctioneersvault Ltd is the data controller only in relation to any direct correspondence you initiate with us (e.g. support emails). Because the extension does not transmit or store personal data on our servers, we do not act as data controller in relation to your use of the extension itself.
Auction Bid Assistant is a browser extension available for Google Chrome, Mozilla Firefox, and Safari (macOS). It helps online auction buyers and auction house staff:
We do not collect any personal data through the Auction Bid Assistant extension. We do not use analytics tools, tracking pixels, crash reporting services, or any form of telemetry within the extension itself. No data from your use of the extension is ever sent to our servers or to any third party.
The website at auction-bid-assistant.com uses Google Analytics (loaded only with your consent via the cookie banner) to understand general site usage. This does not apply to the browser extension.
The extension stores the following information locally on your device only, using the browser's built-in browser.storage.local / chrome.storage.local API:
| Data type | Why it is stored | Where |
|---|---|---|
| Saved lots (title, image URL, price, estimate, lot number, lot URL, platform) | So you can view and manage your saved lots between browser sessions | Your device only |
| Admin-configured featured auction data (auction URLs, scraped lot catalogues, auction house names, sale dates) | So the featured auction grid persists between sessions for all users of the extension on that device | Your device only |
| Extension settings and preferences | To remember your configuration between sessions | Your device only |
This locally stored data never leaves your device, is never transmitted to Auctioneersvault Ltd or any third party, and can be cleared at any time via the extension popup or by removing the extension entirely.

The optional Live Bridge relays live auction bid prices from auction pages to the Auction Bid Assistant web app when both are open simultaneously in your browser. Data passes between tabs using the browser's built-in messaging APIs (chrome.runtime.sendMessage). No personal information is included. No data is sent to Auctioneersvault Ltd's servers. The Live Bridge does not activate unless you have both pages open at the same time.
The Admin panel allows authorised users to configure a curated grid of upcoming auction lots visible to all users of the extension. The admin panel reads publicly available lot data (titles, estimates, images, lot numbers) from supported and sponsored auction house websites — auction houses that appear in the Featured grid have agreed to this arrangement. This data is stored locally in the extension's storage on the device where the admin panel is used. Scraped data contains only publicly available auction information — no personal data is involved.
The extension displays auction lot images, titles, descriptions, and estimates retrieved from third-party auction platforms (the-saleroom.com, easyliveauction.com, and supported auction houses). All such content remains the property of the respective auction houses and original copyright holders. We display this content for informational purposes only to help users track and organise auction lots of interest.
Lot images are displayed as thumbnails for identification purposes. Image URLs are retrieved directly from the auction platforms' public web pages and are not stored on our servers. If you are a copyright holder and believe your content is being used inappropriately, please contact us at support@auction-bid-assistant.com.
We do not share any data with third parties because we do not collect any. The extension contains no advertising networks, analytics services, social media trackers, or third-party SDKs that transmit data. The extension interacts with the following websites solely to deliver features you have explicitly requested:
Your use of these websites is governed by their own privacy policies, separate from this one.
If you are located in the European Economic Area (EEA), the United Kingdom, or Norway, GDPR or UK GDPR applies. Because the extension does not collect or process personal data on our servers, most GDPR rights apply to data held on your own device, over which you have full control.
If you have contacted us by email, you have the right to access, correct, or request deletion of that correspondence. To exercise any of these rights, contact us at the address below. You also have the right to lodge a complaint with your national data protection authority.
Auction Bid Assistant is not directed at children under 13 (or under 16 in the EEA and UK) and does not knowingly collect data from children. The extension is designed for adult auction buyers and auction house professionals.
We retain no user data on our servers. Lot data and featured auction data stored locally by the extension remains on your device until you clear it via the extension popup or uninstall the extension. Support emails are retained only as long as needed to resolve your query.
If we update this policy, the "Last updated" date at the top of the page will change. Continued use of the extension after any changes constitutes acceptance of the updated policy.
