Privacy Policy

Zero-Backend Data Sovereignty

At Calcady™, your privacy is not just a policy — it is hardcoded into our architecture.

Our site operates on a principle of Data Sovereignty. All calculators on this platform execute their mathematical logic entirely client-side — meaning the calculations happen directly inside your web browser.

We do not transmit, collect, or store your personal financial numbers, sensitive health metrics, or trade engineering inputs on our servers. When you close the tab, the data disappears.

Cookies & Local Storage

While we do not track your mathematical inputs, we do use industry-standard web technologies to ensure the site functions correctly:

• Performance & Analytics: We use basic analytics (such as Google Analytics or native Hostinger logs) to understand gross traffic patterns, popular pages, and performance bottlenecks. These services may set cookies in your browser to distinguish unique visitors without identifying who you are.
• UI Persistence: We may use Local Storage in your browser to remember UI preferences, such as keeping you in "Dark Mode" or saving a specific tab state. This data lives exclusively on your hard drive.

Third-Party Links

Our website may contain links to external sites that are not operated by us (including links to professional services or IRS/Government reference materials). If you click on a third-party link, you will be directed to that third party's site. We strongly advise you to review the Privacy Policy of every site you visit. We have no control over and assume no responsibility for the content, privacy policies, or practices of any third-party sites or services.
