Privacy Policy

1. Introduction

SwiftCalc ("we", "our", or "us") operates the website https://swiftcalc.in (the "Site"). This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you visit our Site. Please read this policy carefully. If you do not agree with the terms of this Privacy Policy, please do not access the Site.

We reserve the right to make changes to this Privacy Policy at any time and for any reason. We will alert you about any changes by updating the "Last updated" date of this Privacy Policy. You are encouraged to periodically review this Privacy Policy to stay informed of updates.

2. Calculator Data — No Collection

All calculations, inputs, and results on SwiftCalc are processed entirely within your web browser using client-side JavaScript. No calculation data is transmitted to our servers or stored in any database.

When you input financial information (such as salary, loan amounts, interest rates, or tax details) or health metrics (such as height, weight, or age), this data remains exclusively on your device. We have no technical ability to access, view, or store your calculator inputs or results. This applies to all 80+ calculators across all language variants of the Site.

3. Automatically Collected Information

When you visit the Site, our hosting infrastructure and analytics services may automatically collect certain information about your device and browsing session, including:

• IP address (anonymized where possible)
• Browser type and version
• Operating system
• Referring URL (the page that linked you to our Site)
• Pages visited and time spent on each page
• Device screen resolution and language preference

This information is collected through standard web server logs and Google Analytics 4 for the purpose of understanding traffic patterns, improving the user experience, and diagnosing technical issues. This data is not linked to any personally identifiable information.

4. Cookies and Tracking Technologies

SwiftCalc uses cookies and similar tracking technologies for the following purposes:

• Essential Cookies: We use a single localStorage entry to remember your dark/light mode theme preference. This is stored locally on your device and is never transmitted to our servers.
• Analytics Cookies: Google Analytics 4 may place cookies to measure how visitors interact with the Site, including which pages are most popular and how long users spend on each page. This data is aggregated and anonymized.
• Advertising Cookies: Google AdSense and/or Ezoic may place cookies on your browser to serve relevant advertisements based on your browsing history across the internet. These cookies are managed by Google and Ezoic, not by us.

You can control cookies through your browser settings. Most browsers allow you to refuse cookies or alert you when a cookie is being placed. Please note that disabling cookies may affect the functionality of certain features on the Site.

5. Third-Party Advertising

We use Google AdSense and may use Ezoic to display advertisements on the Site. These advertising networks use cookies and similar technologies to serve ads based on your prior visits to this and other websites. Google's use of advertising cookies enables it and its partners to serve ads based on your visit to the Site and/or other sites on the Internet.

You may opt out of personalized advertising by visiting Google Ads Settings. Alternatively, you can opt out of third-party vendor cookies by visiting the Digital Advertising Alliance opt-out page.

6. Affiliate Links and Recommendations

Some pages on the Site may contain affiliate links to third-party financial services (such as brokerage platforms, loan comparison websites, tax filing services, or insurance providers). If you click on an affiliate link and make a purchase or sign up for a service, we may receive a small commission at no additional cost to you.

Affiliate relationships do not influence our calculator results or the accuracy of any computations on the Site. Calculator outputs are determined solely by the mathematical formulas documented on each tool page.

7. Children's Privacy

The Site is not intended for children under the age of 13. We do not knowingly collect personal information from children under 13. If we discover that a child under 13 has provided us with personal data, we will delete it immediately from our records.

8. Data Security

We use industry-standard security measures to protect the integrity of the Site, including HTTPS encryption for all page requests, HTTP security headers (X-Content-Type-Options, X-Frame-Options, X-XSS-Protection), and strict Referrer-Policy settings. Since we do not store personal financial or health data on our servers, the risk of a data breach involving your calculator inputs is zero.

9. Your Rights

Depending on your jurisdiction, you may have the right to access, correct, or delete your personal data. Since SwiftCalc does not collect or store personal calculator data, there is no personal data for us to provide, correct, or delete in relation to your calculator usage.

For questions related to analytics or advertising data, you may exercise your rights by adjusting your browser cookie settings, using the Google Ads opt-out tools linked above, or contacting us directly.
