Privacy

This static website does not require an account to use the calculator or read the guides.

External calculator runtime

The calculator loads files from an external TestNav service. When your browser requests those resources, the external provider may receive ordinary web-request information such as IP address, browser information and request timing under its own policies.

Hosting logs and analytics

Your web host may keep standard server logs. If analytics or advertising is added later, this privacy page should be updated before those services are enabled.

Cookies

The local calculator wrapper may store a display-scale preference in browser storage so zoom settings can be remembered on supported devices.
