Calculator inputs

Tools calculate in your browser. They do not send input values to this site, save them in browser storage, or create an account. Downloaded CSV files are created locally. Refreshing or closing the page can discard your inputs.

Advertising and analytics

This version includes no advertising or analytics scripts, tracking pixels or optional tracking cookies. An ads.txt file identifies the intended advertising publisher but does not itself display ads or track visitors. This notice and any necessary privacy controls must be updated before advertising or analytics are enabled.

Hosting and email

Once hosted, ordinary server logs may record request information such as IP address, time, requested page and browser details for operation and security. Exact retention depends on the hosting configuration. If you email us, your email provider and ours process the message. Include only information needed for your request.

External links and requests

External references have their own privacy practices. Contact the publisher for questions or requests concerning information you supplied. We do not ask children to submit personal information and do not intentionally collect children’s personal details through these tools.
