GaugeCalc ("we", "us", "this site") publishes free calculator tools for security and electrical technicians. This page explains what data is collected when you use gaugecalc.com and the choices you have about it.
How the calculators themselves work
Every calculator on this site runs entirely in your browser using JavaScript. The numbers you type in — camera counts, resolutions, load values, and so on — are processed on your device and are never sent to our servers, stored, or seen by us. Closing or refreshing the page clears everything you entered.
Cookies and advertising
This site may display ads served by Google AdSense. Google and its partners use cookies and similar technologies to serve ads based on your prior visits to this and other websites. Google's use of advertising cookies enables it and its partners to serve ads based on your visit to this site and/or other sites on the internet.
Analytics
We may use privacy-respecting analytics (such as aggregate visit counts and which pages are viewed) to understand which tools are useful and where the site can be improved. This data is anonymized and is not linked to your calculator inputs.
What we don't do
We don't require account creation, we don't ask for your name, email, or payment details to use any calculator, and we don't sell personal data — because we don't collect any in the first place through the tools themselves.
Third-party links
Some guide pages link to external resources (manufacturer datasheets, code bodies, etc.). We aren't responsible for the privacy practices of those external sites — check their own policies if you visit them.
Children's privacy
This site is intended for working technicians and tradespeople and is not directed at children. We do not knowingly collect data from children under 13.
Changes to this policy
If this policy changes, the updated version will be posted on this page with a new "last updated" date.
