Privacy Policy

Last updated: August 29, 2026

1. Introduction

Welcome to WhatTheCalculator. We respect your privacy and are committed to protecting your personal data. This Privacy Policy explains what data we collect, how we use it, how we protect it, and your rights under data protection laws, including the General Data Protection Regulation (GDPR).

2. Disclaimer - Not Professional Advice

⚠️ Important Notice

The calculators and tools provided on this website are for informational and entertainment purposes only. They are NOT intended to replace professional advice.

  • Health calculators (sleep debt, water intake, etc.) are not medical advice. Always consult a qualified healthcare professional.
  • Financial calculators (spending trackers, budget tools, etc.) are not financial advice. Consult a certified financial advisor for personalized guidance.
  • Lifestyle calculators provide estimates based on general assumptions and may not reflect your specific circumstances.

By using our calculators, you acknowledge that you are solely responsible for any decisions you make based on the results. We are not liable for any consequences arising from the use of our tools.

3. Information We Collect

We may collect the following types of information:

  • Information you provide directly when contacting us via email or forms
  • Basic server logs processed by our hosting provider (such as IP address, browser type, and pages requested) for security and site delivery
  • Calculator input data (processed in your browser only — we do not store your calculator inputs on our servers)

We currently do not use Google Analytics, Google AdSense, or other advertising or analytics tracking tools on this website.

4. How We Use Your Information

We use your information for:

  • Operating, maintaining, and improving the Website and calculator services
  • Responding to inquiries and communicating with you
  • Improving calculator functionality and user experience
  • Complying with legal obligations and preventing abuse or fraud

5. Calculator Data Storage

Important: All calculator inputs and results are processed locally in your browser. We do not collect, store, or transmit your personal calculator data (such as your coffee spending, sleep hours, or toilet paper usage) to our servers.

Any data you enter remains on your device unless you explicitly choose to share results or contact us with that information.

6. Cookies & Tracking

We currently do not use analytics cookies, advertising cookies, or third-party tracking technologies on this website. Our calculators run in your browser without requiring you to create an account.

Our hosting provider may process limited technical data (such as IP address and browser type) in server logs to deliver the site securely. This is standard for any website and is not used by us for profiling or advertising.

If we reintroduce analytics or advertising in the future, we will update this policy and obtain consent where required by law before using non-essential cookies.

7. Third-Party Services

We use third-party service providers only as needed to host and deliver the Website, such as our hosting and content delivery infrastructure. These providers may process limited technical data on our behalf to keep the site available and secure.

We do not sell your personal information to third parties.

8. Affiliate Links & Partnerships

Affiliate Disclosure: WhatTheCalculator may contain affiliate links to products or services. When you click on these links and make a purchase, we may earn a commission at no additional cost to you.

We only recommend products or services that we believe may be valuable to our users. Affiliate partnerships do not influence the functionality of our calculators or the accuracy of our tools.

Affiliate links are clearly marked where they appear on our website. Your decision to click on affiliate links and make purchases is entirely voluntary.

9. Data Retention

Personal data is retained only as long as necessary to fulfill the purposes outlined in this policy, comply with legal obligations, resolve disputes, and enforce agreements.

  • Contact form submissions and email correspondence are retained for up to 2 years unless deletion is requested
  • Server logs retained by our hosting provider are kept according to their standard retention periods

10. Data Security

We implement appropriate technical and organizational measures to protect your data, including:

  • Encrypted connections (HTTPS) for all data transfer
  • Access control to limit data access to authorized personnel only
  • Regular security updates and vulnerability checks
  • Secure hosting infrastructure with industry-standard protections

In the event of a data breach, we will promptly investigate, notify affected users when required by law, and take steps to mitigate risks.

11. Children's Privacy

Our Website may be used by individuals under 18 for educational and practical purposes (such as homework calculators or learning tools). We do not knowingly collect personal information from children without parental consent.

  • Calculator inputs are processed locally and not stored on our servers
  • We do not use advertising or analytics tracking on this website

If you believe we have inadvertently collected personal information from a child, please contact us immediately.

12. Your Rights

Depending on your jurisdiction (especially under GDPR if you're in the EU/EEA), you have the following rights:

  • Right to access - Request a copy of your personal data
  • Right to rectification - Request correction of inaccurate data
  • Right to erasure - Request deletion of your personal data
  • Right to withdraw consent - Withdraw consent for cookies or data processing at any time
  • Right to object - Object to certain types of processing
  • Right to restriction - Request restricted processing of your data
  • Right to data portability - Receive your data in a portable format
  • Right to lodge a complaint - File a complaint with your local data protection authority

To exercise any of these rights, please contact us using the information provided below.

13. International Data Transfers

Data may be transferred and processed outside the European Economic Area (EEA) when you use the Website or contact us, for example through our hosting infrastructure. Where required, we rely on appropriate safeguards such as Standard Contractual Clauses or other mechanisms approved under applicable data protection law.

14. Do Not Track Signals

Some browsers have "Do Not Track" features. Our website currently does not respond to Do Not Track signals. Because we do not use analytics or advertising trackers, there is no tracking preference to manage beyond your browser settings.

15. Changes to This Policy

We may update this Privacy Policy periodically to reflect changes in our practices, technology, legal requirements, or other factors. The "Last updated" date at the top indicates the most recent revision.

We encourage you to review this policy regularly. Continued use of the website after changes constitutes acceptance of the updated policy.

16. Contact Information
