Privacy Policy

Last Updated: October 3, 2026

1. Introduction

TopCalculator.net ("we," "our," or "us") is committed to protecting your privacy. This Privacy Policy explains how we handle information when you visit our website and use our calculators.

2. Information We Do NOT Collect

We prioritize your privacy by NOT collecting:

• Calculator Input Data: We do not collect, store, or transmit any data you enter into our calculators
• Calculation Results: All results stay in your browser and are never sent to our servers
• Personal Information: We do not collect names, email addresses, phone numbers, or other personal identifiers (unless you voluntarily contact us)
• Financial Data: No credit card information, bank details, or financial data is collected
• Health Data: No health information entered into health calculators is stored or transmitted
• Account Data: We do not require user accounts or logins

3. How Our Calculators Work

All calculations on TopCalculator.net are performed using JavaScript in your web browser. This means:

• Your input data never leaves your device
• Calculations happen entirely on your computer or mobile device
• Results are displayed only to you in your browser
• No data is transmitted to our servers during calculations
• Refreshing the page clears all entered data

4. Information We May Collect

While we don't collect calculator data, we may collect minimal, non-personal information for website functionality and improvement:

4.1 Server Log Information

Like most websites, our web server may automatically collect standard information including:

• IP addresses
• Browser type and version
• Operating system
• Referring website
• Pages visited and time spent on pages
• Date and time of access

This information is used solely for website maintenance, security, and improving user experience. We do not use it to identify individual visitors.

4.2 Cookies and Local Storage

We may use minimal cookies or browser local storage for:

• Remembering user preferences (like dark mode settings)
• Improving website functionality
• Analyzing website traffic with Google Analytics (see Section 5)

You can control cookies through your browser settings. Disabling cookies may affect some website features but will not prevent calculator use.

5. Third-Party Services

We keep third-party services to a minimum. The services currently used on this website are:

• Google Analytics 4 (Google LLC): every page loads the Google tag (gtag.js). Google Analytics sets first-party cookies (such as _ga) and collects usage information such as pages visited, referring site, approximate location derived from your IP address, device and browser type, and interactions with the page. We use this aggregated information to understand which calculators are useful and to improve the site. The numbers you type into calculators are not sent to Google Analytics. Google's use of this data is described at How Google uses information from sites that use its services. You can opt out with the Google Analytics Opt-out Browser Add-on or by blocking cookies in your browser.
• jsDelivr CDN: a few calculators that draw charts load the open-source Chart.js library from cdn.jsdelivr.net. As with any file download, the CDN receives your IP address and browser information.

We do not currently display advertising. If we add advertising or other third-party services, we will update this policy before doing so.

6. Contact Form Data

If you contact us via email at [email protected], we will collect:

• Your email address
• Your name (if provided)
• The content of your message

This information is used solely to respond to your inquiry and is not shared with third parties. We retain contact emails only as long as necessary to address your request.

7. Children's Privacy

TopCalculator.net is intended for educational use and may be used by children under 13 with parental supervision. We do not knowingly collect personal information from children under 13. Parents should supervise their children's internet use.

8. Data Security

We implement appropriate security measures to protect against unauthorized access, alteration, or disclosure of information. However, since we do not collect calculation data, there is no calculator data to secure on our servers.

9. Your Rights

You have the right to:

• Use our calculators without providing any personal information
• Clear your browser data at any time to remove any locally stored preferences
• Disable cookies through your browser settings
• Contact us with privacy concerns or questions
• Request deletion of any contact information if you've emailed us

10. Do Not Track

There is no common industry standard for Do Not Track (DNT) signals, and Google Analytics does not change its behavior in response to them. We do not track you across other websites ourselves. To stop analytics collection on this site, use the opt-out options described in Section 5.

11. International Users

TopCalculator.net can be accessed from anywhere in the world. By using our website, you consent to the processing of information as described in this Privacy Policy, regardless of your location.

12. Changes to This Privacy Policy

We may update this Privacy Policy from time to time to reflect changes in our practices or legal requirements. We will post the updated policy on this page with a new "Last Updated" date. We encourage you to review this policy periodically.

13. Educational Purpose Disclaimer

TopCalculator.net is provided for educational purposes only. We do not use calculator data for research, marketing, or any other purpose because we do not collect it.
