Privacy Policy

1. Overview

UnitConverter ("we", "us", "our") operates the unit conversion tool available at this website. We are committed to protecting your privacy. This policy explains what information is collected when you use our service, how it is used, and your choices regarding that information.

2. Information We Collect

We do not collect personally identifiable information. All unit conversions are performed locally in your browser. No input values, conversion results, or calculation history are transmitted to our servers.

We use the following third-party services which may collect anonymous usage data:

• Google Analytics — collects anonymous data including IP address (anonymised), browser type, device type, pages visited, and session duration. This helps us understand how visitors use the site.
• Google AdSense — may collect cookie data to serve relevant advertisements based on your browsing behaviour.

3. Cookies

Our site uses cookies for the following purposes:

• Google AdSense cookies — used to serve personalised or contextual advertisements.
• Google Analytics cookies — used to track anonymous usage statistics.
• localStorage (currency cache) — we store currency exchange rates in your browser's localStorage for up to 30 minutes to reduce API calls. This data contains no personal information.

You can control or disable cookies through your browser settings. Disabling cookies may affect the functionality of third-party features like advertising personalisation, but will not affect the core unit conversion functionality.

4. Google AdSense & Advertising

We participate in the Google AdSense programme to display advertisements. Google uses cookies to serve ads based on your prior visits to this and other websites. Google's use of advertising cookies enables it and its partners to serve ads based on visits to our site and/or other sites.

You may opt out of personalised advertising by visiting Google Ad Settings. You can also opt out via the Digital Advertising Alliance opt-out page.

We do not control the content of advertisements shown by Google. Advertisements do not constitute endorsements by us of any product or service.

5. External APIs

Our currency converter fetches live exchange rates from third-party financial data providers (including Frankfurter/ECB, ExchangeRate-API, and CurrencyAPI). These API requests are made server-side through our own proxy route and include no personal user data beyond the requested currency code. We do not log individual user currency requests.

6. Data Retention

We do not store personal data on our servers. Currency rate data is cached server-side for up to one hour for performance. Browser localStorage data (currency cache) is stored on your device for up to 30 minutes and can be cleared at any time by clearing your browser data.

7. Children's Privacy

This website is not directed at children under the age of 13. We do not knowingly collect any personal information from children. If you believe a child has provided personal information through our site, please contact us and we will delete it promptly.

8. Third-Party Links

Our site may contain links to third-party websites. We are not responsible for the privacy practices or content of those sites. We encourage you to read the privacy policies of any third-party sites you visit.

9. Changes to This Policy

We may update this Privacy Policy from time to time to reflect changes in our practices or applicable law. Any changes will be posted on this page with an updated "Last updated" date. Continued use of the site after changes constitutes acceptance of the revised policy.
