Nothing you calculate is collected
Every calculator on AmpCalcs runs entirely in your browser. The values you enter are processed on your device and are not sent to us or stored on a server. There is no account, no sign-up and no login.
Advertising and cookies
This site is supported by third-party advertising, including Google AdSense. Third-party vendors, including Google, use cookies 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 to you based on your visits to this site and/or other sites on the Internet. You can opt out of personalised advertising by visiting Google Ads Settings. For more on how Google uses information from sites that use its services, see Google's advertising technologies page.
Feedback you choose to send
If you use the feedback form, we receive the message you write and, only if you choose to enter it, your email address. We use these solely to reply and to improve the calculators, and we do not sell or share them.
Server logs
Like most websites, our hosting provider may record standard technical information in server logs — such as your IP address, browser type and the pages you request — for security and to keep the site running. We do not use these logs to identify you.
Your choices
You can block or delete cookies in your browser; the calculators keep working because they do not depend on cookies. You can control personalised advertising through the Google Ads Settings link above.
