Privacy Policy

Last updated: January 2025

1. Introduction

CalcVerse is a free, browser-based calculator hub designed to give you powerful computation tools without compromising your privacy. This policy explains how we handle — or more accurately, don't handle — your data.

Our guiding principle is simple: your calculations are your business, not ours. Every operation you perform stays entirely within your browser.

2. Data Collection — What We Don't Collect

Unlike most web services, CalcVerse collects no personal data whatsoever. Specifically, we do not collect:

  • Names, emails, or contact information — there are no accounts or sign-ups.
  • Calculation history — all history is stored temporarily in your browser's memory and is erased when you close or refresh the page.
  • IP addresses — we do not log, store, or process IP addresses.
  • Cookies or tracking identifiers — CalcVerse sets no cookies and uses no tracking pixels.
  • Device fingerprints or browser signatures — we perform zero device fingerprinting.
  • Location data — your geographic location is never accessed or inferred.

3. How Calculations Work

Every calculator on CalcVerse runs 100% client-side using standard JavaScript math functions built into your browser. When you press "equals" or "calculate," the computation happens locally on your device. No data is transmitted to any server, API, or third-party service.

This includes sensitive calculations such as loan amounts, BMI values, age computations, and currency conversions. All exchange rates for the currency converter are embedded directly in the page's source code and are not fetched from external services at runtime.

4. Third-Party Services

CalcVerse loads two external resources for visual presentation only:

  • Google Fonts — for typography. Google may log font requests according to their own privacy policy, but no personal data is sent beyond a standard HTTP request for CSS files.
  • Font Awesome — for icons, loaded from a CDN. No user data is transmitted during this request.

Neither service receives any of your calculation inputs or results.

5. Browser Storage

CalcVerse does not use localStorage, sessionStorage, IndexedDB, or any other persistent browser storage. Calculation history exists only in JavaScript variables during your session and is garbage-collected when you navigate away or close the tab.

6. Analytics and Advertising

There are no analytics scripts and no advertisements on CalcVerse. We do not use retargeting, behavioral tracking, or any form of user profiling.

7. Security

  • The site is served over HTTPS where available, encrypting all traffic.
  • No user-generated content is stored or rendered, eliminating XSS attack vectors.
  • The codebase is static HTML/CSS/JS with no server-side processing.

8. Accuracy Disclaimer

CalcVerse provides calculations for general informational and convenience purposes. Results should not be used as the sole basis for financial, medical, legal, or engineering decisions. Always verify important calculations with a qualified professional.

9. Children's Privacy

CalcVerse is suitable for all ages. Since we collect no data, there is no risk to children's privacy.

10. Changes to This Policy

If we ever change this policy, we will update this page with a new "Last updated" date. We will never introduce data collection retroactively.

11. Your Rights

Under GDPR, CCPA, and similar regulations, you have rights regarding personal data. Since CalcVerse holds zero personal data, there is nothing to access, correct, delete, or port.

12. Contact

If you have questions about this policy or discover a security issue, please reach out through the contact page.

13. Open Source

CalcVerse's full source code is available for inspection. You can verify every claim in this policy by reading the code — there are no hidden trackers, no obfuscated scripts, and no server calls. Transparency is the ultimate privacy guarantee.
