Privacy Policy
Last updated 13 November 2026. This page describes, plainly, what data this site does and does not collect.
Who runs this site
The kVA to Amps Calculator site is built and maintained by Ian Welkins. Contact details are on the contact page; the same inbox (ianwelkins@gmail.com) handles privacy questions.
What this site collects
Very little, by design. The site has no accounts, no sign-up, no comments and no contact form. It does not ask for your name, address, phone number or payment details, and it never receives them.
Calculations happen in your browser
Every calculator on this site runs locally in your browser. The values you type — kVA, amps, voltages — are never transmitted to a server, stored, or shared. When a calculator writes its state into the page URL (for example ?kva=100&v=400) so you can bookmark or share a result, that happens on your device; the values travel only if you choose to send the link to someone yourself.
Hosting and server logs
The site is served by Cloudflare Pages. Like any web host, Cloudflare processes basic technical data to deliver pages and protect the service — your IP address, browser type and the pages requested — in server logs that are kept for a limited period. That processing is governed by Cloudflare's own privacy policy. The site operator does not build profiles from these logs or use them for marketing.
Cookies
This site does not set cookies of its own. It installs no analytics or advertising scripts at present, so no third-party tracking cookies are set through this site either. If that changes, this policy will be updated before or at the same time, and the change will be described here.
Advertising
When advertising is enabled on this site in the future, Google AdSense may set ad cookies and use them to serve and measure ads, as described in Google's advertising policies. Until advertising is enabled, no ad cookies are set. The conditional wording is deliberate: this page will be rewritten in the present tense when ads actually go live.
Links to other sites
Pages here link to standards bodies and reference publications (NFPA, IEEE, IEC, NIST and similar). Those sites have their own privacy policies, and this one does not cover them.
Children's privacy
This is a technical reference tool for adults doing electrical calculations. It is not directed at children and collects no data from anyone, child or adult, beyond the hosting logs described above.
Changes to this policy
If the site's practices change — for example if analytics or advertising are introduced — this page will be updated and the date at the top changed. Material changes will be described in plain language, not buried.
