Privacy Policy

Last updated: 2026-09-13

This calculator collects no personal data. There is no account to create, no login, and no server that your calculations are sent to.

• Calculations happen entirely in your browser. Nothing you type or calculate is transmitted anywhere.
• History and preferences (your calculation history, theme, and angle-unit setting) are stored only in your browser's local storage, on your device. They are never sent to us or anyone else. Clearing your browser data removes them permanently.
• No cookies. No accounts. No advertising or tracking scripts of any kind.
• No analytics are currently used on this site.

If any optional feature is ever added that requires a network request (for example, a clearly-labeled currency-conversion tool), it will be off by default, clearly marked in the interface, and this policy will be updated to describe exactly what data that specific feature sends and to whom before it ships.

Questions about this policy can be sent to myngerptyltd@gmail.com.
