Privacy Policy — CalculatorNova

1. Client-Side Execution

CalculatorNova is built around a client-side architecture. When you enter numbers, metrics, or formulas into any of our calculators (such as Mortgage, BMI, or Percentage), those calculations execute entirely inside your web browser. Your computation data is never transmitted to our servers or saved in a remote database.

2. Local Storage & Client History

We use your browser's standard localStorage API for the following convenience features:

Calculation History: Saves your recent calculation steps locally so you can review them in the History panel.
Theme Preferences: Stores your active appearance mode (Light/Dark) and accent color choice.
Language Preference: Stores your selected language locale.
Cookie Consent: Stores whether you accepted or declined optional analytics and user insight cookies.

This information remains strictly on your device. You can clear your calculation history at any time using the "Clear History" button in the History menu or by clearing your browser's site data.

3. Web Analytics (Google Analytics & Cloudflare)

To understand how our calculator utilities are discovered, used, and perform across devices, CalculatorNova uses Google Analytics (provided by Google LLC) and Cloudflare Web Analytics. These services use first-party cookies (such as _ga) and browser telemetry to collect aggregated, anonymous information, including:

Pages and specific calculators visited
Approximate geographic region (country or city level; IP addresses are anonymized)
Browser type, operating system, and device viewport dimensions
Referring websites, search terms, and navigation duration

Google Analytics does not record your input values, calculation numbers, or private financial/biometric calculations.

For detailed information on how Google collects, uses, and protects data, please review How Google uses information from sites or apps that use our services and the Google Privacy Policy.

Opt-Out Options: You can decline analytics tracking at any time by selecting Essential Only in our on-site cookie controls (see top of this page), or by installing the official Google Analytics Opt-out Browser Add-on.

4. User Experience Insights (Microsoft Clarity)

We partner with Microsoft Clarity and Microsoft Advertising to capture how you use and interact with our website through behavioral metrics, heatmaps, and session replay to improve and market our products/services. Website usage data is captured using first- and third-party cookies and other tracking technologies to determine the popularity of products/services and online activity. Additionally, we use this information for site optimization, fraud/security purposes, and advertising.
