Privacy Policy

Cardmarket Currency Converter • Last Updated: [Insert Date]

1. Introduction

This Privacy Policy describes how Cardmarket Currency Converter ("we", "us", or "the Extension") collects, uses, and discloses information, and what choices you have with respect to the information.

We respect your privacy and are committed to protecting it. This extension is designed to enhance your browsing experience on Cardmarket by converting currency values locally on your device.

2. Information We Collect

Personal Information

We do not collect, store, or transmit any personally identifiable information (PII) such as your name, email address, physical address, or phone number. You do not need to create an account to use this Extension.

Non-Personal and Technical Information

To function correctly, the Extension may process the following data:

Web Page Content: The Extension reads the HTML content of the Cardmarket pages you visit solely to identify price elements and convert them to your selected currency. This processing happens locally on your device.
Currency Preferences: We store your selected target currency (e.g., USD, PLN, GBP) in your browser’s local storage (chrome.storage) to remember your settings for future visits.

3. How We Use Your Information

The data processed by the Extension is used strictly for the following purposes:

Functionality: To identify prices on the Cardmarket website and display the converted value next to them.
User Preferences: To remember your preferred currency settings so you do not have to select them every time you open the browser.

4. Third-Party Services and APIs

To provide accurate currency conversion, this Extension fetches current exchange rates from a third-party API.

Exchange Rate API: We use
Data Transmission: When the Extension updates exchange rates, a request is made to this third-party service. This request may expose your IP address to the API provider as part of standard internet communication protocols.
No Tracking: We do not send your browsing history or the specific URLs you visit to this third-party API. Only a request for exchange rate data (e.g., "Get EUR to USD rate") is sent.

5. Browser Permissions

The Extension requires specific permissions to function. Here is an explanation of why we request them:

"host_permissions" or "activeTab" (Cardmarket): This is required to access the text on Cardmarket websites to find prices and insert the converted prices. We do not access data on any other websites.
"storage": This is required to save your currency preference and the last cached exchange rate locally on your browser.

6. Data Retention

Local Data: Your preferences are stored locally on your device until you uninstall the Extension or clear your browser data.
External Data: We do not maintain a database of user data.

7. Changes to This Policy

We may update our Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page and updating the "Last Updated" date.
