Privacy Policy

Last updated: November 9, 2026. This policy describes the site as currently built. Items marked [TODO] must be completed by the site owner before production, especially if analytics, cookies, advertising, or third-party services are added later.

What we collect

As currently built, ProjectCalc collects and stores no personal data on any server. There is no account system, no backend, and no database. Calculator inputs stay in your browser and are never transmitted.

Local storage

The site stores one preference in your browser's local storage: your chosen unit system (US or metric), so calculators open the way you left them. You can clear it through your browser settings at any time.

Analytics, cookies, and advertising

No analytics, advertising, or third-party tracking services are currently installed, and this policy makes no claim that they are. [TODO: if analytics, cookie consent, or advertising is added before launch, disclose each service here, its purpose, and the data it collects, and update this policy accordingly.]

Third-party services

None are currently used. [TODO: disclose any hosting provider or embedded services before launch if applicable.]

Children's privacy

The site is a general-audience tool and does not knowingly collect personal information from anyone, including children, because it collects no personal information at all.

Changes to this policy

If the site's data practices change — for example by adding analytics — this policy will be updated with the new details and the date above.
