Privacy Policy

1. 100% On-Device Calculation Processing

Every calculator on CalculatorGraph executes locally inside your web browser. When you enter income, loan amounts, SIP contributions, tax deductions, BMI/health measurements, or network subnet parameters, those numbers are processed in your device’s memory and are never transmitted to any backend calculation server.

2. Local Browser Storage (localStorage) & User Control

To improve your experience without requiring user accounts or logins, CalculatorGraph stores three optional preferences in your browser’s local storage:

• Saved Favorites (calculatorgraph_favorites_v1): Calculators you explicitly bookmark using the Save button.
• Recently Used Tools (calculatorgraph_recent_v1): The slugs of your most recently visited calculators for quick access on the homepage.
• Theme Preference (calculatorgraph_theme_v1): Your chosen Light or Dark interface mode.

You can erase your saved favorites and recent calculator history at any time with a single click using the Clear Saved History button in the website footer or homepage panel.

3. Privacy-Safe Scenario URL Sharing

Unlike calculators that continuously write your sensitive health, salary, or debt numbers into the browser address bar as you type, CalculatorGraph keeps canonical URLs clean by default. Input parameters are encoded into a shareable link (?share=1&...) only when you explicitly click the Share button.

4. Cookies, Third-Party Trackers & Advertising

CalculatorGraph does not sell personal data, does not require account registration, and does not embed behavioral advertising trackers or cross-site tracking pixels.
