1. Overview
NumberPunch (numberpunch.com) respects your privacy. This policy explains what information we collect, how we use it, and your choices regarding that information.
2. Information We Collect
Information you provide directly:
Currently, NumberPunch does not require you to create an account or provide any personal information to use the calculators. No name, email address, phone number, or payment information is collected through calculator use.
If we introduce account features, invoicing, or payment processing in the future, this policy will be updated to reflect what personal information is collected and how it is used.
Information collected automatically:
When you visit NumberPunch, certain information is collected automatically through third-party analytics and advertising services:
- Google Analytics 4 (GA4): Collects anonymous usage data including pages visited, time on site, device type, browser type, approximate geographic location (city/region level), and referral source. GA4 uses cookies to distinguish unique visitors. No personally identifiable information is collected by GA4 on our site.
- Google Tag Manager (GTM): Manages the loading of analytics and advertising tags. GTM itself does not collect personal data but facilitates the services listed here.
- Microsoft Clarity: Records anonymous session replays and heatmaps to help us understand how visitors interact with the site. Clarity captures mouse movements, clicks, and scrolls but does not capture text entered into form fields (calculator inputs). Clarity may use cookies for session identification.
- Google AdSense: Serves advertisements on the site. AdSense uses cookies and web beacons to serve ads based on your prior visits to this site and other sites on the internet. Google's advertising cookies enable it and its partners to serve ads based on your browsing activity. You may opt out of personalized advertising by visiting Google's Ads Settings.

You can control cookies through your browser settings. Disabling cookies may affect the functionality of analytics and advertising but will not affect calculator functionality.
