Privacy Policy
1. Overview
NumberPro ("we", "us", or "our") operates the website usenumberpro.com. This Privacy Policy describes how we handle information when you use our free calculator tools. We are committed to protecting your privacy and being transparent about our practices.
2. Information We Collect
NumberPro does not require registration or account creation. All calculator inputs you enter are processed entirely in your browser and are never transmitted to our servers. When you visit our site, standard web server logs may record your IP address, browser type, referring URL, and pages visited. We use Google AdSense and/or Ezoic to display advertisements. These third-party advertising partners may set cookies and use web beacons to serve personalized ads based on your browsing activity.
3. How We Use Information
We use information to operate and improve the NumberPro website and tools, to display relevant advertisements that keep NumberPro free, to analyze aggregate usage patterns (no personally identifiable data), and to comply with legal obligations.
4. Data Sharing
We do not sell, rent, or trade your personal information to third parties. We may share aggregated, non-personally-identifiable statistics with advertising partners. We may disclose information if required by law or to protect the rights and safety of NumberPro and its users.
5. Advertising & Third-Party Services
NumberPro is supported by advertising. We use Google AdSense and/or Ezoic, which may use cookies to serve ads based on your prior visits to our site or other sites. Ad scripts are loaded lazily — only after your first interaction with the page — to minimize impact on page performance.
6. Children's Privacy
NumberPro is not directed to children under the age of 13. We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us and we will delete it promptly.
7. Data Security
Since all calculations are performed client-side in your browser, your calculator inputs never leave your device. We implement reasonable technical measures to protect our website infrastructure from unauthorized access.
8. Your Rights
Depending on your jurisdiction, you may have rights to access, correct, or delete personal data we hold about you. Since we collect minimal data, most requests can be addressed by clearing your browser cookies. For other requests, contact us using the information below.
9. Changes to This Policy
We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated "Last updated" date. Continued use of NumberPro after changes constitutes acceptance of the revised policy.
