Sold Stats for eBay, published by Soldstat · last updated 16 August 2026

The short version: this extension has no server. It does not collect, transmit or sell your data. Everything it calculates is worked out inside your own browser. Since version 0.3.0 it also keeps a history of the searches you look at, so their prices can be charted over time — that history is written to your own computer and is never sent anywhere.

What the extension does

When you are on an eBay search results page, Sold Stats reads the listings already displayed on that page and calculates statistics from them: sell-through rate, median and typical sold prices, and how many items sold over the period visible. To compare sold listings against active ones it also requests the same search in the opposite view from eBay, exactly as your browser would if you clicked the filter yourself.

It then saves those figures, once per day per search, so that a chart can be drawn later. eBay itself only shows sold listings for roughly the last 90 days; keeping the numbers is the only way to see further back. The extension's own page, opened from its toolbar icon, reads that history back.

Data collected

None. Specifically, the extension does not collect:

personally identifiable information, including your name, address, email or age
health, financial or payment information
authentication information, passwords or credentials
personal communications
location data
your browsing history or web activity
analytics, telemetry, usage statistics or crash reports

“Collect” here means what it means in the Chrome Web Store programme policies: transmitting data off your machine. The searches you look at are written to your own computer, as described under What is stored on your computer, and are never transmitted.

Where data goes

Nowhere. There is no backend, no API key, no analytics provider and no third party of any kind. The developer cannot see what you search for, because nothing is ever sent to the developer. The only network request the extension makes is to ebay.com (and its national domains), for the search page you are already looking at.

What is stored on your computer

Two things, both local to your machine, in the browser's own extension storage. This storage is not synced to your Google account.

Search history. For each eBay search whose panel you have seen: the search terms and filters, the site (such as ebay.com), and one set of figures per calendar day — median and typical sold price, sell-through, number sold, number of active listings, sales per day. Alert settings and any note you type are stored alongside. A search you pinned is kept until you unpin it; a search you merely passed by is forgotten after about 45 days.
A short-lived page cache. Fetched eBay pages are held in memory for a few minutes so that revisiting a search does not re-request it. It is capped to a handful of searches and disappears when the browser stops the extension's background process. Nothing is written to eBay's own storage.

None of this leaves your computer. There is nowhere for it to go: the extension has no account system and no server to send it to.

Deleting it

Removing the extension deletes everything it stored. To clear the history while keeping the extension, open its page from the toolbar icon and unpin the searches you no longer want, or use Chrome's Remove extension and install it again for a clean slate. There is no copy anywhere else to ask us to delete.

Permissions, and why each is needed

Access to eBay domains (ebay.com, ebay.co.uk, ebay.de, ebay.fr, ebay.it, ebay.es, ebay.ca, ebay.com.au). Required to read the search results page and to request the matching sold or active view. eBay only shows sold listings to a signed-in user, so the request is made with your existing eBay session, the same one your browser already uses. Your credentials are never read, stored or transmitted anywhere by the extension.
Storage. Required to keep the search history described above on your own computer between browsing sessions. It grants no access to anything outside the extension's own storage area.

No other permissions are requested. The extension reads pages only on eBay search pages.

Changes to this policy

If a future version ever changes what the extension handles, this page will be updated before that version is published, and the date at the top will change.
