Privacy Policy

1. Introduction

Welcome to calculator-free.com ("we," "us," or "our"). We are committed to protecting your privacy and being transparent about how information is collected and used when you visit our website. This Privacy Policy applies to all pages and tools on calculator-free.com, including our mortgage calculator, BMI calculator, tip calculator, savings calculator, and percentage calculator.

By using calculator-free.com, you agree to the collection and use of information in accordance with this policy. We do not require any registration, account creation, or login to use any of our calculators. All calculator computations run entirely in your browser — no form data is submitted to or stored on our servers.

This policy is written in plain language to make it easy to understand. If you have questions about anything in this policy, please contact us at [email protected].

2. Information We Collect

We collect two categories of information: information provided automatically by your browser and device when you visit our site, and information collected by third-party services we use (Google AdSense and Google Analytics).

2.1 Automatically Collected Information

When you visit calculator-free.com, the following information may be collected automatically through standard web server logs and third-party analytics tools:

• IP address — your internet protocol address, which may be used to determine your approximate geographic region (country/city level)
• Browser type and version — e.g., Chrome 124, Safari 17, Firefox 125
• Operating system — e.g., Windows 11, macOS 14, Android 14
• Referring URL — the page or search engine that sent you to our site
• Pages visited and time on page — which calculator pages you visited and for how long
• Device type — desktop, mobile, or tablet
• Screen resolution and language settings

We do not collect names, email addresses, phone numbers, or any personally identifiable information unless you voluntarily contact us by email.

2.2 Calculator Inputs

All calculations on calculator-free.com are performed entirely within your browser using JavaScript. Numbers you enter into our calculators (loan amounts, body weight, bill totals, etc.) are never transmitted to our servers and are not stored anywhere. When you close or refresh the page, your inputs are gone. We have no access to any values you enter.

3. How We Use Information

The automatically collected information described above is used for the following purposes:

• Website analytics — to understand which calculators are most popular, how users navigate the site, and where improvements are needed
• Performance monitoring — to identify technical issues, slow-loading pages, or broken features
• Advertising — to serve relevant advertisements via Google AdSense (see Section 4 below)
• Security — to detect and prevent abusive traffic, bots, or denial-of-service attacks

We do not sell, rent, or trade your information to any third party. We do not use your information for email marketing, re-targeting campaigns, or to build personal profiles.

4. Google AdSense & Cookies

calculator-free.com is monetized through Google AdSense, a third-party advertising program operated by Google LLC. Google AdSense uses cookies and web beacons to serve ads that are relevant to your interests based on your browsing history across websites.

Specifically, Google AdSense may:

• Set cookies on your device to track your browsing behavior across websites in the Google Display Network
• Use your browsing history to show you interest-based ("personalized") advertisements
• Collect data about which ads you see, click, and how long you view them
• Use the DoubleClick cookie to track ad impressions and clicks for fraud prevention and billing purposes

We use AdSense publisher ID ca-pub-5798786176755576. We do not control the specific cookies Google sets or how Google uses the data collected through AdSense. Google's use of advertising cookies is governed by Google's own Privacy Policy, available at policies.google.com/privacy.

You can opt out of personalized advertising by visiting Google's Ad Settings or by visiting aboutads.info/choices. You can also disable cookies entirely in your browser settings, though this may affect how some websites function.

5. Google Analytics

We may use Google Analytics, a web analytics service provided by Google LLC, to understand how visitors use calculator-free.com. Google Analytics collects information such as how often users visit the site, what pages they visit, and what other sites they used prior to coming to our site. We use this information only to improve the site.

Google Analytics collects the IP address assigned to you on the date you visit this site, but not your name or other identifying information. We do not combine the information collected through Google Analytics with personally identifiable information. Although Google Analytics plants a cookie on your web browser to identify you as a unique user the next time you visit, the cookie cannot be used by anyone but Google.

You may opt out of Google Analytics tracking by installing the Google Analytics Opt-out Browser Add-on.

6. Google Fonts

We use Google Fonts to load the Inter typeface used throughout the site. When your browser loads our pages, it makes a request to Google's font servers at fonts.googleapis.com. This request includes your IP address and browser information, which Google may log. We do not control this data collection. You can read about how Google handles font requests in their privacy policy at policies.google.com/privacy.

7. Third-Party Links

calculator-free.com may contain links to third-party websites for reference or informational purposes. We are not responsible for the privacy practices of those sites. When you leave our website, we encourage you to read the privacy policy of every website you visit. This Privacy Policy applies only to information collected by calculator-free.com.

8. Your GDPR Rights (European Users)

If you are located in the European Economic Area (EEA), United Kingdom, or Switzerland, you have certain rights under the General Data Protection Regulation (GDPR) and equivalent local laws. These rights include:

• Right of access — You have the right to request a copy of the personal data we hold about you.
• Right to rectification — You have the right to request correction of any inaccurate personal data.
• Right to erasure ("right to be forgotten") — You can request that we delete any personal data we hold about you, subject to certain exceptions.
• Right to restrict processing — You can request that we limit how we use your data in certain circumstances.
• Right to data portability — You have the right to receive your personal data in a structured, machine-readable format.
• Right to object — You have the right to object to our processing of your personal data for direct marketing or legitimate interests purposes.
• Rights related to automated decision-making — You have rights relating to automated decisions that significantly affect you.

Because we collect minimal personal data directly (no accounts, no forms, no newsletter), most GDPR rights primarily relate to data held by our third-party providers (Google). To exercise your rights regarding Google's data, visit myaccount.google.com or Google's Privacy Policy.

To exercise any rights you believe we can fulfill directly, contact us at [email protected] and we will respond within 30 days.

9. Your CCPA Rights (California Residents)

If you are a California resident, the California Consumer Privacy Act (CCPA) provides you with specific rights regarding your personal information. You have the right to:

• Know what personal information we collect, use, disclose, and sell about you
• Delete personal information we have collected from you (with some exceptions)
• Opt-out of the sale of your personal information — We do not sell personal information.
• Non-discrimination — We will not discriminate against you for exercising your CCPA rights

To submit a CCPA request, contact us at [email protected] with the subject line "CCPA Request." We will respond within 45 days of receiving your request.

10. Children's Privacy

calculator-free.com is not directed at children under the age of 13, and we do not knowingly collect personal information from children under 13. Our calculators are general-purpose tools that anyone may use, but we do not target children and do not use any data collected from users known to be under 13 for any purpose.

If you are a parent or guardian and believe your child has provided us with personal information, please contact us at [email protected] so we can take appropriate action to delete that information.

11. Data Security

We take reasonable technical and organizational measures to protect the information we collect. Our website is served over HTTPS, which encrypts data in transit between your browser and our servers. However, no method of transmission over the internet or electronic storage is 100% secure, and we cannot guarantee absolute security.

Since our calculators do not transmit your inputs to any server, there is no risk of your financial or health data being intercepted in transit or stored insecurely on our end.

12. Changes to This Policy

We may update this Privacy Policy from time to time to reflect changes in our practices, technology, or legal requirements. When we make material changes, we will update the "Last Updated" date at the top of this page. We encourage you to review this policy periodically. Your continued use of calculator-free.com after any changes constitutes your acceptance of the updated policy.
