Privacy policy

1. Who we are and what this policy covers

Fee Calculator for eBay Sellers is a browser extension for Google Chrome, published by an independent developer. It is not made, endorsed or sponsored by eBay Inc. This policy explains what the extension does with your data, what our website at feecalculator.page does, and what rights you have. It applies to the extension itself and to the pages of feecalculator.page (the front page, the welcome page, the uninstall page, the "Wrong numbers?" page and this policy).

The short version: the extension works inside your browser and does not send your data anywhere.

2. What data the extension handles

The extension does not send personal data to us or to anyone else, and we do not sell it. The data described below is handled only on your device.

• The item page you open. The extension runs only on item pages of eBay.com (addresses that start with www.ebay.com/itm/). On such a page it reads the item number, title, price or current bid, the shipping the buyer pays and the category (from the breadcrumbs or the category number on the page), so it can work out eBay's fees in your browser. It does not read your eBay account, Seller Hub, messages, orders or buyers' details, and it does not run on any other website.
• Your costs. The item cost, your shipping and packaging that you type are kept for your recent items (up to 40, by item number) with the browser's built-in chrome.storage.local API, so a listing you reopen shows the same numbers.
• Saved items. When you click Save, the item number, title, a link to the item built from its number, the price, shipping, your costs, the fee category, the profit and the date are saved (up to 10 items) in chrome.storage.local. Export CSV creates a file on your computer only when you click it.
• Settings. Your store level, Top Rated Plus, promoted listings rate, sales tax, international buyer, whether the panel is folded the last tab of the extension window and the numbers you last typed in its Manual tab are saved the same way, in chrome.storage.local, on this device only. The extension does not use Chrome sync.
• No accounts. The extension has no sign-up, no login and no user profiles. It does not know your name or your eBay account.
• No tracking inside the extension. The extension contains no analytics, no advertising code and no remote code, and it makes no network requests. The fee table is a file inside the extension.

Chrome Web Store disclosure. Our Chrome Web Store listing declares Website content, because the extension reads the price, shipping, title and category from the item page, and Web history, because saved items keep a link to the item. That data stays on your device.

3. Cookies and analytics on our website

The front page, the welcome page and this policy page on feecalculator.page use Google Analytics 4 to count visits. This happens only on the website, not inside the extension. The uninstall page has no analytics. The welcome page also reports whether the extension's icon is pinned to your toolbar. We never send Google Analytics your costs, saved items or anything the extension reads from eBay. Advertising features are off for everyone.

If you are in the European Economic Area, the United Kingdom or Switzerland, analytics cookies are off. Google works out your country from your IP address. In those places Google Analytics sets no cookies and stores no identifier on your device. The Google script still loads and can send Google a basic signal without a cookie: the page you opened, the time, your browser and device type, and your approximate location.

Everywhere else, analytics cookies are on by default. Google Analytics sets cookies named _ga and _ga_*, which can last up to two years, and processes the same technical data.

Your browser connects to Google to load the script, so Google sees your IP address. Google says Google Analytics 4 uses it to estimate location and does not store it. Statistics are kept for 14 months (see section 8).

Your choice. This website does not ask for consent, so visitors from the European Economic Area, the United Kingdom and Switzerland stay without analytics cookies.

You can also block cookies in your browser settings, use a content-blocking extension or install Google's opt-out add-on. The website keeps working without them. Google's own privacy policy describes how Google processes this data.

Server logs. Like any web server, ours keeps a technical log of requests to these pages: IP address, the address requested, the time, the browser type and, if your browser reports it, the page you came from. We use it to keep the site running and safe, and it is deleted automatically after a short time. The extension sends nothing to this log; only opening one of these pages does.

4. How we use data

The only data we receive is the aggregated website statistics and server logs described above and, if you choose to send them, your answer on the uninstall page and any email you write to us. We use the statistics to see how many people reach the welcome page, the logs to keep the site running and safe, and your answers and emails to reply to you and to improve the extension. We do not build individual profiles and we do not combine this data with any other source.

When you remove the extension, Chrome opens a short page on our website that asks why. Answering is optional. Only if you press Send, the reason you picked and the text you typed (up to 500 characters) go to our server, which passes them to us as a message in Telegram with the name of the extension and does not store them. To stop spam, the server counts answers per day by a one-way hash of your IP address with a key that changes every day; the hash is kept for 2 days and is never part of the message. The uninstall page has no analytics and sets no cookies. Please do not put personal details in your answer.

The use of information received from Google APIs will adhere to the Chrome Web Store User Data Policy, including the Limited Use requirements.

5. Who we share data with

We do not sell or rent data, and we share it only with the services named here. They process data for us: Google Analytics, as a service provider for the website statistics in section 3; Telegram, which delivers answers from the uninstall page to us (it receives the extension name, the reason and the text you send, but not your IP address or any install ID); and our hosting and email providers, which store the server logs and the emails you send us. Please do not put personal details in your answer on the uninstall page. We have no server that receives data from the extension.

6. Your rights, including under the GDPR

If you are in the European Economic Area, the United Kingdom or Switzerland, you have the right to access, correct or delete personal data about you, to restrict or object to its processing, and to lodge a complaint with your local data protection authority. Because the extension stores data only on your device, you can exercise these rights yourself at any time (see section 8). For website analytics, you can opt out as described in section 3. For anything else, write to [email protected] and we will answer within 30 days.

This website does not ask for consent, so it sets no analytics cookies in those places. The legal basis for the basic signal without cookies, for website analytics elsewhere and for server logs is our legitimate interest in understanding how the website is used and keeping it safe. The legal basis for emails and uninstall page answers you send us, and for counting those answers by the IP hash, is our legitimate interest in replying to you, improving the extension and preventing spam. The legal basis for keeping your costs, saved items and settings is that you asked the extension to save them.

7. Children

The extension and the website are not directed at children under 13 (or under the age set by your country's law). We do not knowingly collect data from children. The extension sends nothing to us, so we hold no such data from it.

8. Data retention and deletion

Your costs, saved items and settings live in your browser only and stay there after you close it. You can delete a saved item, or clear the whole list, at any time in the Saved tab of the extension window. Removing the extension from Chrome deletes all of this data. Website analytics data is kept by Google Analytics for the retention period set in our account (14 months) and then deleted automatically. Server logs are deleted automatically after a short time. We keep emails only as long as we need them to reply or to improve the extension, and you can ask us to delete them. Answers from the uninstall page stay in our private Telegram chat until we delete them; our server keeps only the daily counts and the IP hash described in section 4, for 2 days.

9. Changes to this policy

If we change this policy, we will update the text on this page and the date at the top. Please check this page from time to time if you want to stay informed.
