Privacy Policy

NumPad.net ("we," "us," or "our") operates a collection of free professional calculator and lookup tools at numpad.net. This Privacy Policy explains how we collect, use, and share information when you use our site.

Usage data. We collect standard server log data including IP addresses, browser type, referring URLs, pages visited, and timestamps. This data is used to understand how tools are being used and to improve site performance.

Tool inputs. Calculations and lookups you perform are processed client-side in your browser when possible. We do not store the specific values you enter into our calculators or lookup tools.

Cookies. We use cookies and similar tracking technologies to support advertising and analytics. Third-party ad partners may also set cookies on your device when you visit our site.

We use the information we collect to:

• Operate and improve the tools on NumPad.net
• Analyze traffic and usage patterns via analytics services
• Display advertisements through third-party ad networks
• Comply with legal obligations

NumPad.net displays ads served by third-party advertising networks, which may include Ezoic and Google AdSense. These networks may use cookies and web beacons to serve ads based on your prior visits to this site and other sites on the internet. You can opt out of personalized advertising by visiting aboutads.info or networkadvertising.org/choices.

We use analytics services such as Google Analytics to collect aggregated, anonymized data about site usage. Google Analytics may collect information about your device and browsing behavior. You can learn more at policies.google.com/privacy.

Some tools on NumPad.net make requests to third-party APIs (such as the NPPES NPI Registry and OpenFDA) to retrieve lookup results. These requests may include query parameters you enter. We do not control how those services handle data — please review their respective privacy policies.

Server log data is retained for up to 90 days. We do not maintain a database of user-submitted calculator inputs or lookup queries.

NumPad.net is not directed at 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.

Depending on your location, you may have rights regarding your personal data, including the right to access, correct, or delete data we hold about you. To make a request, contact us at the email below.

We may update this Privacy Policy from time to time. The updated date at the top of this page reflects the most recent revision. Continued use of the site after changes constitutes acceptance of the updated policy.
