The short version
We collect zero personal identifying data. All calculations happen entirely inside your browser. We have no accounts, use standard analytics to monitor site traffic, and have no advertising. Your inputs never leave your device.
1. Who We Are
Online Calculator World ("we," "our," or "us") operates this website, providing a suite of free online calculator and conversion tools. This Privacy Policy explains what information we do and do not collect when you use our services.
2. Information We Collect
We collect no personal identifying information. Specifically:
- We do not require registration or account creation.
- We do not collect your name, email address, or any personal identifying information.
- We do not store or transmit any values you enter into our calculators.
- We use standard web analytics (Google Analytics) to measure aggregate site performance and traffic.
- We do not display advertising that tracks users.
All calculation logic is executed client-side using JavaScript running in your browser. Your inputs are processed locally and are never sent to any server.
3. Technical Log Data
Like all websites, our hosting provider may collect standard server log data when you access our site. This may include:
- Your IP address (anonymized or in aggregate form depending on the host)
- Browser type and operating system
- Pages visited and referring URLs
- Timestamps of access
This data is collected and controlled by our hosting provider and is governed by their privacy policy. We do not access or use this log data to identify individual users.
4. Cookies
Our site does not use cookies for tracking user-identifying info. If your browser stores any data locally (e.g., via localStorage for UI preferences), this information never leaves your device and is not accessible to us. Google Analytics may place cookies to distinguish unique users, which are governed by Google's policy.
5. Third-Party Services
We use Google Analytics to monitor traffic. Other than this, we do not embed third-party tracking scripts, advertising networks, or social media widgets on our pages. External links to third-party websites are provided for informational purposes only. Once you navigate to an external site, their own privacy policy applies.
6. Children's Privacy
Our website is suitable for users of all ages. Because we collect no personal information, there are no special concerns regarding children's privacy. We do not knowingly collect data from anyone under the age of 13 (or applicable local age threshold).
7. Your Rights
Because we collect no personal data, there is nothing to access, correct, export, or delete. If you are located in the European Economic Area (EEA), the United Kingdom, or California, your privacy rights under GDPR, UK GDPR, or CCPA are effectively honored by default — we simply have no data about you.
8. Changes to This Policy
We may update this Privacy Policy occasionally. Any changes will be posted on this page with an updated "Last updated" date. Because we do not have your email, we cannot notify you directly — we encourage you to review this page periodically.
