1. Who we are

CalcBox ("we", "us", "our") operates the website https://calcboxapp.com. This Privacy Policy explains what data we collect, how it is used, and the choices you have.

2. Information we collect

We do not require registration and we do not sell personal data. The numbers and values you type into our calculators are processed entirely in your browser and are never sent to or stored on our servers.

Like most websites, our hosting and analytics providers automatically receive technical information when you visit, such as your IP address (truncated for analytics), browser type, device type, language, referring page, and pages viewed.

3. Cookies and similar technologies

We use cookies and similar technologies to remember your preferences, measure traffic, and (with your consent) display personalized advertising. You can accept, reject or change your choice at any time using the cookie banner shown on your first visit, or by clearing this site's data in your browser.

4. Analytics

We use Google Analytics 4 to understand aggregate usage (pages visited, country, device type). Analytics data is anonymized and used only to improve the site. You can opt out by installing the Google Analytics Opt-out Browser Add-on.

5. Advertising — Google AdSense

This site displays advertisements served by Google AdSense, a third-party advertising service provided by Google LLC. Google and its partners may use cookies and device identifiers to serve ads based on your prior visits to this and other websites.

You can opt out of personalized advertising at any time by visiting Google Ads Settings or learn more about how Google uses information from sites that use its services at policies.google.com/technologies/partner-sites.

Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits. Users may opt out of personalized advertising by visiting www.aboutads.info (US) or www.youronlinechoices.eu (EU).

6. Your rights (GDPR / CCPA)

If you are in the European Economic Area, the United Kingdom, or California, you have the right to access, correct, delete, or restrict processing of your personal data, as well as the right to data portability and to lodge a complaint with a supervisory authority.

7. Children's privacy

CalcBox is not directed to children under 13 (or the equivalent minimum age in the relevant jurisdiction). We do not knowingly collect personal information from children.

8. Data retention and security

We retain analytics data only for as long as needed to operate and improve the service. We use industry standard measures to protect the limited data we process.
