Privacy Policy
eBay Fee & Profit Calculator — web tool and Chrome extension. Last updated September 18, 2026.
The short version
This tool collects nothing. There is no account, no analytics and no advertising, and we run no server that receives your work. Everything you enter stays on your own device.
1. What is covered
This policy covers the eBay Fee & Profit Calculator Chrome extension (version 1.1.0) and the eBay Fee Calculator page on NoxaKit. It sits alongside the site-wide privacy policy.
2. Data we collect
None. We do not collect, transmit, sell or share any personal or usage data, and we operate no server that receives your input.
The extension makes no network requests of any kind. There is no server to send anything to.
3. What is stored on your device
So the tool remembers your setup between visits, the following is saved locally, via Chrome's extension storage:
- Your calculator settings: eBay site, business or private seller, category, seller level, ad rate, tax rate and theme
- The numbers you type into the calculator, and the cost you enter against individual eBay items
If Chrome Sync is switched on, Chrome may sync the extension's settings across your own devices under your Google account. That is handled by Google under your Chrome settings and never reaches us. Clearing your browser data, or removing the extension, deletes everything listed above.
4. What the extension reads
- The item price, postage price and category breadcrumb of the eBay listing you are viewing, so the panel can calculate fees
This reading happens inside your browser, only on the page you are looking at, and only to produce the result shown on screen. Nothing read from a page is sent to us, and nothing is kept beyond what section 3 lists.
5. Permissions and why they exist
storage— Saves your settings (eBay site, seller type, category, ad rate) and the costs you type in, on your own device.
Site access is limited to:
- eBay item pages only (/itm/* on ebay.co.uk, ebay.com, ebay.de, ebay.fr, ebay.it, ebay.es, ebay.com.au, ebay.ca, ebay.ie, ebay.at, ebay.nl, ebay.be, ebay.ch and ebay.pl)
6. What we do not do
- No analytics, tracking pixels, fingerprinting or advertising
- No accounts, sign-in or email collection
- No selling or sharing of data, because there is no data to sell
- No sending the pages or numbers you work on to us — we never receive them
- No remote code: the extension ships all of its code inside the package
7. Children
This is a general-purpose tool for people running a business or a website. It is not directed at children, and it collects no personal information from anyone.
8. Changes
If this policy changes materially, the "Last updated" date above changes with it, and the change is noted in the updates list on the tool page.
