Calculator data stays on your device
All 21 calculators run in your browser. The current, voltage, power factor, battery size, generator rating, motor efficiency, charger settings and every other value you enter never leave your device. Nothing is saved after you close the page, and copying a result only writes it to your own clipboard.
Cookies, analytics and ads
AmpToKW sets no cookies and runs no analytics, advertising or tracking scripts. Language links are plain web addresses, not stored preferences. This policy will be updated before any analytics is added.
Third parties
The site loads no outside fonts, scripts, maps or video embeds. Our hosting provider receives standard request data (IP address, browser type, page requested and time) to deliver pages and block abuse, and keeps server logs for a limited time. We do not sell or rent personal data.
Contact messages
The contact form opens your own email app with your message filled in; nothing is sent until you press send there. We receive your name, email address and message, use them only to reply or fix the problem you report, and delete the conversation once it is resolved unless the law requires us to keep it.
Your rights
Depending on where you live, you can ask to access, correct, delete or export your personal data, and to object to or restrict its use. You can also complain to your local data protection authority.
