Measurements, labels and calculations are processed in your browser. This version has no account system, advertising scripts, analytics scripts or application upload endpoint.
CSV files are generated locally when you request an export. Part labels that could start spreadsheet formulas are prefixed with an apostrophe in the export.
The static hosting provider may process ordinary web requests and access logs under its own policy. This is separate from the local calculation data.
If analytics or advertising is added in a future version, this page should be updated to describe those services before they go live.
