Privacy Policy
Last updated: 2026
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
CalcBox may display third-party advertisements. When ads are shown, they may be served by advertising partners such as Google, which use cookies to serve ads based on your prior visits to this or other websites. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to our site and/or other sites on the Internet.
You may opt out of personalized advertising by visiting Google Ads Settings, or opt out of a third-party vendor's use of cookies for personalized advertising at www.aboutads.info. Advertising partners are bound by their own privacy policies, which we encourage you to review.
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. To exercise any of these rights, contact us at contato@calcboxapp.com.
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.
9. Changes to this policy
We may update this Privacy Policy from time to time. The "Last updated" date at the top of this page will reflect any changes.
