Privacy Policy

Last updated: October 8, 2026

This policy explains what information is collected when you use CalcWorthy (https://calcworthy.com) and how it is used.

Calculator inputs stay on your device

All calculations run in your web browser. The values you enter into a calculator are not transmitted to or stored on our servers. If you use the "Copy link" button, your inputs are placed in the link so you can share it; they are only seen by whoever you share the link with.

Anonymous usage statistics

To learn which calculators are useful, we count page views and whether a calculator was used. This counter uses no cookies and does not store your IP address; it records only the page, the type of event, the website that linked to us, your browser's language setting and whether the device is a phone. It cannot identify you.

Log data

Like most websites, our hosting provider automatically records standard server logs (such as IP address, browser type, pages requested and the time of the request) for security and to keep the site running. These logs are not used to identify you personally.

Advertising and cookies

We use Google AdSense to show advertisements. Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to this website or other websites. Google's use of advertising cookies enables it and its partners to serve ads to our users based on their visits to this site and/or other sites on the Internet.

You may opt out of personalized advertising by visiting Google Ads Settings. You can also opt out of some third-party vendors' use of cookies for personalized advertising by visiting www.aboutads.info. To learn more about how Google uses information from sites that use its services, see How Google uses information from sites or apps that use our services.

Visitors from the European Economic Area, the United Kingdom and Switzerland are shown a consent message, provided by Google, before personalized ads or advertising cookies are used. You can change your choice at any time from the privacy link in that message.

Your choices

You can block or delete cookies through your browser settings. The calculators keep working without cookies.

Children

This site is intended for a general audience and is not directed at children under 13. We do not knowingly collect personal information from children.

Your rights

Depending on where you live (for example under the GDPR or the CCPA), you may have the right to access, correct or delete personal data and to object to certain processing. Because we do not store calculator inputs or create user accounts, we generally hold no personal data about you. For any request, contact contact@calcworthy.com.

Changes

We may update this policy from time to time. The date at the top of this page shows when it was last changed.
