1. Overview
FuelMileageCalculator.com ("we", "us", "our", or "the site") is operated by James Will. This Privacy Policy explains what information we collect, how we use it, and what choices you have. We are committed to handling your data transparently and in accordance with the EU General Data Protection Regulation (GDPR), the UK Data Protection Act 2018, the California Consumer Privacy Act (CCPA), and Google's Publisher Policies.
The short version: the calculator runs entirely in your browser, and we do not collect the numbers you type into it. We do, however, use Google Analytics to understand how visitors use the site, and we use Google AdSense to display advertising. Both of those services set cookies, and the rest of this document explains exactly what that means for you.
2. Information We Collect Directly
FuelMileageCalculator.com does not require an account. We do not ask for your name, email address, or any other identifying information in order to use the calculator. The fuel-up data, odometer readings, and unit selections you enter into the calculator are processed entirely in your web browser; the values never leave your device, are not transmitted to our servers, and are not stored by us in any form.
If you choose to contact us by email, we will naturally receive whatever personal information you include in your message. We use that information solely to respond to your enquiry and to keep records of our correspondence. We do not add you to any marketing list, and we do not share your email with third parties.
3. Google AdSense and Third-Party Advertising
We use Google AdSense, a third-party advertising service provided by Google Ireland Limited and Google LLC, to display advertisements on some pages of the site. Google AdSense uses cookies, web beacons, and similar technologies to serve ads based on a user's prior visits to this site and/or other sites on the internet. Google's use of advertising cookies enables it and its partners to serve ads based on your visit to this site and/or other sites on the internet.
Information that may be collected by Google on your behalf includes: your IP address, the type of browser and operating system you are using, the pages you visit on this site and the time you spend on each page, the referring URL (the previous web page that linked you to ours), and a pseudonymous identifier stored in a Google cookie. Google may also associate this information with your Google account if you are signed in, in which case the data becomes part of your Google account profile and is governed by Google's Privacy Policy.
You may opt out of personalised advertising by visiting Google Ads Settings. You may also opt out of certain third-party vendors' use of cookies for personalised advertising by visiting www.aboutads.info (for US visitors) or www.youronlinechoices.eu (for EU/UK visitors).
Some of the advertising served on this site may be from third-party networks other than Google. Each of those networks is governed by its own privacy policy, which is typically accessible from the ad itself or from the network's website.
4. Google Analytics
We use Google Analytics 4 to collect aggregate, anonymised statistics about how visitors use the site. Google Analytics sets first-party cookies that store a pseudonymous client identifier and record the time of your visit, the pages you viewed, the referring source, and basic device information (screen size, browser family, operating system family). We have enabled IP anonymisation so that the last octet of your IP address is removed before the data is stored by Google. We do not enable Google Analytics' advertising features, and we do not share Analytics data with any third party.
You can opt out of Google Analytics on all sites by installing the Google Analytics Opt-out Browser Add-on. The add-on is available for most modern desktop browsers.
5. Cookies We Use
Cookies are small text files that a website stores in your browser. The cookies set by FuelMileageCalculator.com and by the third-party services we use fall into three categories:
- Strictly necessary cookies, set by the site to remember your theme preference (light or dark mode) and any other small UI state. These cookies expire after a short period (typically 30 days) and do not contain any personal data.
- Analytics cookies, set by Google Analytics to distinguish unique visitors and to record session activity. These cookies expire after two years and contain a pseudonymous identifier.
- Advertising cookies, set by Google AdSense and its partners to deliver and measure personalised and non-personalised advertising, to cap the frequency with which a given ad is shown to you, and to build aggregate interest categories. These cookies typically expire between 30 days and two years.
You can clear or block cookies at any time through your browser settings. Most modern browsers also offer a "Do Not Track" or "Global Privacy Control" option, which we honour by disabling non-essential cookies and analytics when the signal is present.
6. Your Rights
Under GDPR, CCPA, and equivalent legislation, you have the right to access, correct, delete, or export any personal data we hold about you. Because we do not collect or store personal data on this site (the calculator runs client-side and we have no user accounts), most of these rights are moot in practice. Where they do apply, for example, to email correspondence or to data held by Google about you, you can exercise them by contacting us at team@fuelmileagecalculator.com. We respond to verifiable requests within 30 days, and usually much faster.
7. Children's Privacy
FuelMileageCalculator.com is not directed at children under the age of 13, and we do not knowingly collect personal information from children. If you are a parent or guardian and believe that your child has provided personal information to us, please contact team@fuelmileagecalculator.com and we will promptly delete it.
8. Data Retention
We retain email correspondence for as long as it remains useful for the purpose it was collected, and no longer than two years, after which we delete or anonymise it. Google Analytics data is retained by Google for 14 months by default. Google AdSense cookies expire according to the schedule in the Google advertising policies.
9. International Data Transfers
FuelMileageCalculator.com is operated from the United States. By using the site, you understand that your information may be transferred to, stored in, and processed in the United States and in the European Economic Area (where Google maintains its AdSense and Analytics servers). Google adheres to the EU-US Data Privacy Framework and the UK Extension thereto, and we rely on Google's contractual safeguards for any personal data processed on our behalf.
10. Security
We use HTTPS throughout the site, so the data exchanged between your browser and our servers is encrypted in transit. We do not store personal data on our servers, so the attack surface is small. Where personal data is processed on our behalf by third parties (Google), we rely on the security commitments in their respective privacy policies and the technical safeguards documented in their security centres.
11. Changes to This Policy
We may update this Privacy Policy from time to time to reflect changes in our practices, our service providers, or applicable law. The "Last Updated" date at the top of the page will always reflect when the policy was last revised. If the changes are material, we will add a notice on the homepage for at least 14 days. Continued use of the site after a material change constitutes acceptance of the revised policy.
12. Contact
