Privacy Policy & Data Security
Last Updated: September 18, 2026
At ArthCalculator (accessible at https://arthcalculator.in/), we believe that financial information—including your income, tax deductions, loans, investments, and personal net worth—is among the most sensitive personal data you possess. Maintaining absolute confidentiality and earning your trust is foundational to our mission.
This Privacy Policy outlines our strict, privacy-first technical architecture, compliance with the Digital Personal Data Protection Act, 2023 (DPDPA 2023), and our commitment to zero financial data retention.
1. Your Calculations Stay on Your Device (100% In-Browser)
We built ArthCalculator with one clear rule: your financial details belong to you, not our servers. Every single calculation runs completely inside your own web browser using client-side JavaScript.
- Your Numbers Never Leave Your Device: When you enter your salary, loan principal, interest rate, or monthly SIP, those numbers stay on your phone or computer. They are never sent across the internet to our servers or any third party.
- Zero Database Storage: We do not maintain databases to store your inputs. We do not record, log, or track the numbers you calculate.
- Nothing is Saved When You Leave: The moment you close the browser tab, refresh the page, or navigate away, all entered numbers disappear. Nothing is stored in cookies, local storage, or server logs.
2. Information We Never Ask For
To protect your privacy completely:
- No Personal Details: We do not ask for your name, email address, phone number, PAN card, Aadhaar number, bank account, or card numbers.
- No Sign-up or Accounts: All 300+ financial calculators across our 17 specialized hubs are completely free to use without creating an account or logging in.
- No Financial Profiling: Because we never collect your financial inputs, we cannot and do not build profiles, score your finances, or track your personal wealth.
3. Anonymous Website Traffic & Diagnostics
Like most websites, we look at basic, anonymous traffic patterns to keep the site running fast and fix broken pages:
- Website Analytics: We use Google Analytics to see high-level numbers—such as which calculators are visited most, overall visitor counts, and general regions (like city or country). This data is aggregated and cannot identify you personally or connect to any calculation.
- Device Diagnostics: Basic technical details—such as whether you are on mobile or desktop, your screen size, and browser type—help us make sure our calculators display cleanly on every device.
4. Compliance with Digital Personal Data Protection Act, 2023 (DPDPA)
As an Indian website, ArthCalculator fully complies with India's Digital Personal Data Protection Act, 2023 (DPDPA 2023) and respects international standards like GDPR for our NRI visitors:
- Purpose Limitation: We do not collect digital personal data for secondary marketing, lead generation, or profiling purposes.
- Data Minimization: We request only the absolute minimum data required for web page delivery.
- No Cross-Border Data Transfers: Since your financial calculations never leave your device, your personal numbers never cross any network or borders.
5. Cookie Policy
Cookies are small text files placed on your device to ensure optimal website performance:
- Essential Cookies: Required for basic site navigation, stylesheet caching, and security header verification.
- Analytical Cookies: Used by Google Analytics to collect aggregated, anonymous traffic insights.
You can adjust your browser settings at any time to reject or clear cookies. Disabling cookies will not impair or restrict the mathematical functioning of any of our 300+ calculators.
6. Third-Party Links & External Services
Our platform contains educational references and links to official regulatory portals (such as the Income Tax e-Filing portal, RBI, EPFO) and third-party financial services (such as international remittance providers). Once you leave ArthCalculator via an external link, you are subject to the privacy policies and security practices of the destination website. We do not pass or share any local calculation data with external third parties.
7. Platform Security Protocols
We implement modern security engineering protocols, including forced HTTPS with SSL/TLS 256-bit encryption across all URLs, strict Content Security Policies (CSP), and HTTP Strict Transport Security (HSTS) to safeguard code delivery to your browser and prevent man-in-the-middle tampering.
8. Policy Updates & Inquiries
We may update this Privacy Policy periodically to reflect evolving legal standards or platform enhancements. The "Last Updated" timestamp at the top of this document reflects the most recent revision.
