Privacy Policy
Last updated: June 2026
We Collect Nothing
Numvex does not collect any personal data. No names, no emails, no IP addresses, no browser fingerprints, and no tracking of any kind. We do not use cookies for user accounts or personal identification. All calculations run entirely in your browser using client side JavaScript and never leave your device.
How Calculators Work
Every Numvex calculator operates entirely within your web browser. When you enter measurements or values, the computation happens locally on your device. The results are displayed on your screen and are never transmitted to our servers or any third party. Even we cannot see what you calculate.
Cookies and Analytics
We do not use cookies for user accounts, personal tracking, or advertising. The only cookies on our site come from Google Analytics, which helps us understand aggregate traffic patterns such as which pages are most visited. These cookies collect anonymized usage data and do not store personal information. You can disable cookies in your browser settings at any time.
Third Party Services
We use Google Fonts for typography and Google Analytics for anonymous traffic analysis. We do not use advertising networks, retargeting pixels, or social media tracking on our website. We do not sell, trade, or share any information with third parties for marketing purposes.
Data Security
Since we do not collect any user data, there is no personal information to secure, store, or protect. Your calculator inputs and results remain entirely on your device. If you contact us by email, we will have your email address but we do not add it to any mailing list or share it with anyone.
Children Privacy
Since we collect no personal data from any users, our site is safe for users of all ages including children under 13. Parents and guardians can be confident that children can use Numvex calculators without any personal information being collected or shared.

We may update this Privacy Policy from time to time. When we make changes, we will update the Last Updated date at the top of this page. We encourage you to review this page periodically for any changes.
