Our Commitment to You
At Lion Calculator, privacy is not just a policy—it is the foundation of our engineering. We believe that you should be able to calculate your net worth, track your health, or plan your future without fear of being tracked, profiled, or sold as a data point.
1. Local-Only Processing
The most important thing to know about Lion Calculator is that all calculations are performed on the client-side. This means when you enter numbers into a calculator, the logic runs within your own browser. Your inputs are never sent to our servers, never stored in our databases, and never accessible to our team.
2. Information We Do Not Collect
By architectural choice, we do not collect:
- Personal identifiers (Names, Email addresses, Phone numbers).
- Financial specifics (Account numbers or specific balances).
- Health data (Medical history or specific metrics).
- IP addresses linked to your specific calculation history.
3. Anonymous Analytics
To improve our tools and understand which calculators are most helpful, we use privacy-focused, cookieless analytics. This data is fully aggregated and anonymous. We track metrics like "Total visits to BMI Calculator" but never "User X calculated a BMI of 28."
4. Third-Party Links
Our website may contain links to other sites. Please be aware that we are not responsible for the content or privacy practices of such other sites. We encourage our users to be aware when they leave our site and to read the privacy statements of any other site that collects personally identifiable information.
