Privacy Policy

Last updated: July 4, 2026

This policy explains what information PapaCalcs.com ("we", "us") collects, how we use it, and the choices you have. We keep it short and in plain language on purpose.

The short version: our calculators run entirely in your browser and we never receive the numbers you type. We do use standard advertising and analytics services that set cookies, described below.

Information we collect

Calculator inputs

The figures you enter into any calculator are processed locally in your browser to produce a result. They are not transmitted to our servers or stored by us.

Automatically collected data

Like most websites, our hosting and analytics tools automatically record standard technical information such as your approximate location (from IP address), browser type, device type, referring page, and the pages you view. This helps us understand what is useful and fix problems.

Information you send us

If you email us, we receive your email address and whatever you choose to include. We use it only to respond and to improve the site.

Cookies and advertising

We display advertising to keep the calculators free. Our advertising partners, which may include Google AdSense, use cookies and similar technologies to serve and measure ads, including personalized ads based on your prior visits to this and other websites.

Third-party vendors, including Google, use cookies to serve ads based on your visits to this site and others.
Google's use of advertising cookies enables it and its partners to serve ads based on your visits. You can 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 at aboutads.info/choices.
Most browsers let you block or delete cookies in their settings.

We may use analytics services (such as Google Analytics) to measure traffic. These services set their own cookies and process data under their own privacy policies.

How we use information

To operate, maintain, and improve the website and its calculators.
To display and measure advertising.
To respond to messages you send us.
To detect and prevent abuse, and to comply with law.

Sharing

We do not sell your personal information. We share data only with service providers that help us run the site (hosting, analytics, advertising) and when required by law.

Your choices and rights

Depending on where you live, you may have rights to access, correct, or delete personal data we hold, and to opt out of certain advertising. Residents of the EEA/UK (GDPR) and California (CCPA/CPRA) have specific rights. To exercise any of them, email hello@papacalcs.com.

Children

PapaCalcs is intended for parents and other adults. It is not directed to children under 13, and we do not knowingly collect personal information from them.
