What you enter

Numbers you type into a calculator are processed in your browser. They are not sent to our servers or stored by us. If you use “Copy link to these numbers”, your inputs are placed in the page address so you can share them; anyone with that link can see them.

Advertising

We use third-party advertising, including Google AdSense, to keep the site free. Google and its partners 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 personalized advertising by visiting Google Ads Settings, or opt out of some third-party vendors' use of cookies at aboutads.info. Visitors in the EEA, UK and Switzerland are asked for consent before personalized ads are shown.

Analytics

We may use Google Analytics to understand which pages are used, through cookies that collect anonymous usage information such as pages viewed and approximate location. You can opt out with the Google Analytics opt-out browser add-on.

Children

This site is not directed to children under 13, and we do not knowingly collect personal information from them.

Your rights

Depending on where you live, you may have rights to access or delete personal information held about you, including under the CCPA and GDPR. Because we do not store calculator inputs, most requests will concern advertising and analytics cookies, which you can control through your browser and the links above. Contact hello@calcsforlife.com with any request.

Changes

We'll update this page if our practices change, and revise the date above.
