Privacy Policy

Your privacy is not just a policy, it's our architecture.

Effective Date: September 15, 2025

1. Introduction

Welcome to Calculator.bio. We are deeply committed to protecting the privacy of our users. This Privacy Policy outlines our principles and practices, which are designed from the ground up to ensure that your data remains your own. Our core mission is to provide useful scientific tools without compromising your privacy.

2. No Data Collection or Storage

We do not collect, store, transmit, or share any personal data or any data you enter into our calculators.

  • Client-Side Calculations: All calculations performed on Calculator.bio happen exclusively within your web browser on your own device ("client-side"). The information you input (e.g., DNA sequences, concentration values) is never sent to our servers or any third-party service.
  • No User Accounts: We do not require user registration. All tools are accessible anonymously.
  • No Databases: We do not maintain any databases of user-submitted information. Once you close your browser tab, the information you entered is gone.

3. Cookies and Tracking Technologies

Calculator.bio does not use cookies for tracking, analytics, or advertising. We do not use any third-party analytics services (like Google Analytics) or advertising networks that would place tracking cookies on your browser. Your visit to our site is anonymous and is not monitored or analyzed for marketing or other purposes.

4. Server Logs

Like virtually all web servers, our server may keep standard, anonymous access logs for a short period for security and maintenance purposes. These logs may include your IP address, browser type, and the pages you visited. This information is not linked to any personal identity, is not used for tracking, and is periodically deleted. It is used solely to protect the server from malicious activity and to diagnose technical problems.

6. Children's Privacy

Our services are intended for an audience of students, researchers, and professionals and are not directed at children under the age of 13. We do not knowingly collect any information from children. Since we do not collect any personal data at all, we are inherently compliant with regulations like the Children's Online Privacy Protection Act (COPPA).

7. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated effective date. As we do not collect user information, we cannot notify you of changes. We encourage you to review this policy periodically.
