1. Health Data — We Don't Collect It
All health calculators on WellCalc run entirely within your browser using JavaScript. When you enter your height, weight, blood pressure, or any other health data:
- That data never leaves your device
- It is never sent to our servers or any third party
- It is not stored in any database or log file
- It disappears when you close or refresh the page
2. Analytics and Cookies
We may use basic, privacy-respecting website analytics to understand how many visitors we receive and which tools are most popular. Any analytics we use:
- Do not track individual users across sites
- Do not collect personally identifiable information
- Collect only aggregated, anonymised data (page views, country, browser type)
We do not use third-party advertising cookies or retargeting pixels.
