1. Overview
eBay Profit Calculator ("the Extension") is a Chrome browser extension that displays net selling prices and a profit calculator on eBay product listing pages. This Privacy Policy explains what information the Extension accesses, how it is used, and what it does not do.
2. Data We Do Not Collect
The Extension does not collect, store, transmit, or share:
- Personal information of any kind
- Browsing history or visited URLs
- eBay listing data, prices, or product information
- Search queries or purchase behavior
- Device identifiers or IP addresses
- Analytics or usage statistics
3. Data Stored Locally
The Extension stores only the category fee rules you manually configure in the settings (category name and fee percentage). This data is saved using chrome.storage.sync, which is managed entirely by Chrome and may sync across your own devices if you are signed into Chrome sync.
This data never leaves Chrome's own storage system and is never transmitted to any server controlled by this Extension or its developer.
4. Permissions Explained
- storage — to save and retrieve your category fee rules across browser sessions.
- activeTab — to read the category name from the eBay listing page you have open when you click "Add from current page" in settings. This runs only when you explicitly trigger it.
- scripting — required by Chrome to execute the category-reading function on the active tab. It is used only for the "Add from current page" feature.
- Host permissions (ebay.com, ebay.co.uk) — to inject the net price badge and profit calculator into eBay listing pages. The Extension operates exclusively on eBay domains.
5. No Third-Party Services
The Extension does not use any analytics platforms, advertising networks, crash reporting services, or external APIs. No data is sent to any third party, including the developer.
6. No Remote Code
All code that runs in the Extension is bundled within the extension package itself. No scripts, styles, or resources are loaded from external servers at runtime.
7. Children's Privacy
The Extension does not knowingly collect any information from anyone, including children under the age of 13.
8. Changes to This Policy
If this Privacy Policy is updated, the revised version will be published at this URL with an updated effective date. Continued use of the Extension after changes are posted constitutes acceptance of the updated policy.
