Privacy and local data

Calculator values

Current calculator values and results remain on the device while the page is open. A later local-save feature uses local storage only after the visitor explicitly chooses to save a project. Local storage belongs to that browser profile and may be visible to other people using the same profile.

Consent and analytics

Optional Google Analytics activates only after consent. It records anonymous navigation and safe action counts; calculator values, project names, free text, and full query strings are excluded. Behavioral profiling is not used.

Advertising

Advertising is disabled. Placeholder configuration or environment variables do not activate an advertising loader. A separate documented approval and privacy review is required before any later change.

Clear saved data

Use the site's Clear saved data control when local saving is available, or clear this site's storage through browser settings. Withdrawing optional consent stops future optional analytics on that browser; it does not control data already removed under an analytics provider's retention policy.
