1. Overview: Calculations Run in Your Browser
At TDEEGuide.com, we believe your health and biometric metrics are personal. All calculations (age, weight, height, activity level, and body fat percentage) are computed locally inside your web browser via client-side JavaScript. We do not transmit, log, store, or sell your personal biometric inputs to external servers.
2. Information We Automatically Collect
Like most websites, we may collect non-personally identifiable diagnostic information when you access our site, including:
- Browser type, operating system, and device resolution.
- Referring URLs, general geolocation (country/city level), and timestamp of visits.
- Aggregated usage patterns to optimize user experience and page load performance.
3. Cookies and Web Analytics
We may use privacy-preserving analytics and standard cookies to analyze traffic patterns and maintain user interface preferences (such as metric vs imperial units). You can choose to disable cookies through your individual browser settings.
4. Third-Party Advertising and External Links
We use Google AdSense to display advertising. Google, as a third-party vendor, uses cookies (including the DoubleClick cookie) to serve ads based on your visits to this site and other sites on the internet. You can turn off personalised advertising in Google Ads Settings, and you can opt out of some third-party vendors’ use of cookies for personalised advertising at aboutads.info. You can read how Google uses information from sites that use its services at policies.google.com/technologies/partner-sites. Where the law requires it, for example in the UK and the European Economic Area, we will ask for your consent before setting advertising cookies. Pages may also link to external websites, and we are not responsible for their privacy practices.
