Effective date: Last updated:

This Privacy Policy explains how Cash Denomination Calculator (“we”, “us”, “our”), operated at cashdenominationcalculator.github.io, collects, uses, and protects information when you use our website and tools. We are committed to protecting your privacy in compliance with the Information Technology Act, 2000 (India), the Information Technology (Reasonable Security Practices and Procedures and Sensitive Personal Data or Information) Rules, 2011, and the General Data Protection Regulation (GDPR) for visitors from the European Union.

1. Data Controller

The data controller for this website is Cash Denomination Calculator, operated by Supraja and Omprakash from Jaipur, Rajasthan, India. For privacy-related enquiries, contact us at cashdenominationcalculator@gmail.com.

2. Information We Collect

2.1 Information We Do NOT Collect

Cash Denomination Calculator is designed with privacy as a core principle. Our cash denomination calculator:

  • Does not collect, transmit, or store any financial data you enter (denomination counts, totals, etc.)
  • Does not require user registration or login
  • Does not collect names, phone numbers, Aadhaar numbers, PAN numbers, or bank account details
  • Does not use server-side databases to store user information
  • Does not sell, rent, or share personal data with any third party

All calculations happen entirely in your browser using client-side JavaScript. No data is sent to our servers or any third-party server during calculator use.

2.2 localStorage (Browser Storage)

Cash Denomination Calculator uses your browser’s localStorage to store:

  • Theme preference: Your light/dark mode selection
  • Calculation history: Your recent denomination calculations (up to 10 entries) for your convenience

This data is stored only on your device, never transmitted to any server, and can be cleared at any time by clearing your browser data or using the “Clear History” button in the calculator. We cannot access this data.

2.3 Contact Form Data

If you use our contact form, the information you submit (name, email, subject, message) is processed by Formspree and delivered to our team via email. Formspree’s privacy policy applies to this data. We use this information solely to respond to your enquiry and do not add you to any marketing list.

3. Cookies and Third-Party Services

We use Google AdSense to display advertisements on our website. Google AdSense may use cookies and web beacons to serve ads based on your prior visits to our site or other sites on the internet. Specifically:

For details, see Google’s advertising privacy policy.

3.2 Google Analytics (Planned)

We plan to implement Google Analytics to understand how visitors use our website (pages visited, time on site, device type, geographic region). Google Analytics uses cookies to collect anonymised usage data. When implemented:

  • We will enable IP anonymisation to prevent collection of your full IP address
  • We will not enable any advertising features or cross-site tracking
  • You may opt out using the Google Analytics Opt-out Browser Add-on

3.3 Google Fonts

We load the Inter font from Google Fonts. When you visit our site, your browser makes a request to Google’s servers to load the font files. Google’s privacy policy applies to this request.

4. Legal Basis for Processing (GDPR — EU Visitors)

For visitors from the European Economic Area (EEA), our legal basis for processing data is:

  • Legitimate interest: Operating and improving a free public tool (calculator functionality, analytics)
  • Consent: For non-essential cookies (advertising, analytics) — we will implement a cookie consent banner when Google Analytics is activated
  • Contractual necessity: Processing contact form submissions to respond to your enquiries

Under the Information Technology Act and its rules, you have the right to:

  • Request access to any personal data we hold about you
  • Request correction of inaccurate data
  • Withdraw consent for data processing at any time

Since we do not collect personal data through the calculator, these rights primarily apply to contact form submissions.

6. Data Security

We implement reasonable security measures as required under the IT Act, 2000 (Section 43A) and the Reasonable Security Practices Rules, 2011. Since we do not collect or store personal data on any server, the primary security measure is our zero-data-collection architecture. The website is served over HTTPS via GitHub Pages, ensuring encrypted transmission.

7. Children’s Privacy

Cash Denomination Calculator is a general-purpose calculation tool and is not directed at children under the age of 13. We do not knowingly collect personal information from children. If you believe a child has submitted personal information through our contact form, please contact us and we will delete it promptly.

8. Data Retention

  • Calculator data: Not retained (never collected)
  • localStorage data: Retained on your device until you clear it
  • Contact form data: Retained in our email for up to 12 months, then deleted
  • Server logs: GitHub Pages may retain standard web server logs; see GitHub’s privacy statement

9. International Data Transfers

Our website is hosted on GitHub Pages (servers in the United States). If you access the site from outside the US, your connection data may be transferred internationally. Google AdSense and Google Analytics also process data on servers located outside India. These services are covered by their respective privacy policies and data processing agreements.
