Short version: We do not collect, store, or share any personal information you enter into this calculator. Everything runs locally in your browser.
What information we do not collect
When you use the Maintenance Calorie Calculator, you enter personal details such as your age, height, weight, gender, and activity level. None of this data leaves your device. All calculations are performed directly in your browser using JavaScript. No data is transmitted to any server.
What information we may collect automatically
Like most websites, our hosting provider may record standard server log data when your browser requests a page. This typically includes:
- Your IP address (usually anonymised at the network level)
- Browser type and version
- The page you visited and the time of the visit
- The referring URL (which page linked you here)
This data is retained for a maximum of 30 days for security and performance monitoring, and is never linked to any personal profile.
Cookies
We do not use tracking cookies, advertising cookies, or third-party analytics cookies. The site may store your most recent calculator inputs in your browser's localStorage so the form is pre-filled on your next visit. This data never leaves your device and you can clear it at any time by clearing your browser's site data.
Third-party services
We do not embed third-party advertising scripts, social media widgets, or analytics SDKs (such as Google Analytics) on this site. Any external links on the page (such as DOI links to scientific studies or government health sites) open in a new tab and are subject to those sites' own privacy policies.
Children's privacy
This site is intended for users aged 15 and older, consistent with the valid input range of the calculator. We do not knowingly collect information from children under 13.
Changes to this policy
If we make meaningful changes to this policy, we will update the effective date at the top of this page. Continued use of the site after changes constitutes acceptance of the updated policy.
