Privacy Policy

Introduction

This Privacy Policy explains how this website collects, uses, and protects information when you use our free calculators and guides. We designed this site around a simple privacy principle: your financial calculations are your business, and we have no interest in seeing them.

All calculator computations happen locally in your browser using JavaScript. The numbers you enter into any calculator are processed on your device and are never transmitted to our servers, stored in any database, or shared with any third party. We cannot see, access, or recover your inputs.

Information We Collect

We collect only the minimal technical information needed to operate the site. Like most websites, our hosting provider automatically logs standard server data such as your IP address, browser type, requested pages, and timestamps, used solely for security and operational diagnostics.

If you contact us by email, we receive the information you choose to include in your message, which we use only to respond to your inquiry. We do not build profiles, we do not sell data, and we do not share your information with third parties except as required by law.

Cookies

We use a small number of cookies to keep the site working smoothly. Essential cookies remember basic preferences such as your cookie consent choice. We do not use cookies to track your calculator inputs, which never leave your device in the first place.

Our advertising partners may set their own cookies to serve and measure ads, as described in the Advertising section below. You can control cookies through your browser settings at any time: most browsers allow you to block or delete cookies, though blocking essential cookies may affect site functionality.

Advertising

This site displays advertisements served by third-party advertising networks, which help keep every calculator free. These ad providers may use cookies, web beacons, or similar technologies to collect information about your visits to this and other websites, in order to show you ads matched to your interests.

You can learn about these practices and opt out of interest-based advertising through industry programs such as the Network Advertising Initiative opt-out page and the Digital Advertising Alliance’s consumer choice tools. Note that opting out does not remove ads; it only stops them from being personalized.

GDPR and Your Rights

If you are located in the European Economic Area or the United Kingdom, the General Data Protection Regulation gives you specific rights over your personal data, including the right to access, correct, delete, restrict, or port your data, and to object to certain processing. Because our calculators process everything locally and we store no calculation data, there is typically nothing to access or delete.

Our lawful basis for the minimal server logs we process is our legitimate interest in operating and securing the website. For any privacy request, including questions about cookies or advertising, contact us at abdullahkhan.k90912@gmail.com and we will respond within 30 days. You also have the right to lodge a complaint with your local data protection authority.

Children’s Privacy and Changes

This site is intended for a general audience and is not directed at children under 13. We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us and we will delete it promptly.

We may update this Privacy Policy from time to time to reflect changes in our practices or legal requirements. Material changes will be reflected by updating the effective date below. Your continued use of the site after changes constitutes acceptance of the updated policy. Effective date: January 1, 2026.

Data Retention and Security

Because calculator inputs never leave your device, there is no calculation data for us to retain, secure, or breach — the strongest privacy guarantee is architectural. Server logs are retained only as long as needed for security and operational purposes, typically no more than 90 days, and are then deleted or anonymized.

Email correspondence is retained only as long as needed to handle your inquiry. We apply industry-standard security measures to our systems, including encrypted connections (HTTPS) across the entire site. No method of transmission over the internet is perfectly secure, but our minimal-data design means there is very little worth attacking.
