Privacy

MeasureSpark is designed so ordinary calculator inputs stay on your device. No account is required, and the site does not send project dimensions to an application database to calculate a result.

Calculator inputs

Calculations are performed in your browser. Values typed into a calculator update the result on the page and are not attached to a user profile or saved as project history by MeasureSpark.

Local preferences

The online ruler can save a calibration factor in your browser's local storage. You can remove it by clearing site data. Other devices and browsers do not receive that calibration.

Hosting and technical requests

Like most websites, the hosting infrastructure receives technical request data needed to deliver and protect the site, such as the requested URL, time, browser information, and network address. MeasureSpark does not use those records as a measurement-history service.

Analytics, advertising, and cookies

MeasureSpark currently does not include account tracking, an advertising script, or a third-party analytics component in the site application. If one is introduced, this policy will identify the provider, purpose, choices, and relevant retention details.
