Privacy Policy
Last updated: August 2025. This page explains what data is collected when you use CornYieldCalc.com and how it is used.
Overview
CornYieldCalc.com is a free informational website that provides corn yield calculators and agricultural guides. We are committed to being transparent about data collection. In short: we do not ask you to create an account, we do not collect the numbers you type into the calculator, and the only data we gather is anonymous traffic data through Google Analytics and ad-serving data through Google AdSense.
Information We Do Not Collect
We do not collect or store the values you enter into any calculator on this site. All calculator math runs in your browser — the numbers never leave your device. We have no sign-up, no user accounts, and no way to tie a calculation to a person.
Cookies and Tracking Technologies
We use two third-party services that may set cookies on your browser:
- Google Analytics 4 — provides anonymous traffic data such as page views, country, device type, and how visitors found the site. We use this to understand which calculators and guides are most used so we can improve them. IP addresses are anonymized.
- Google AdSense — serves ads on the site to keep it free. AdSense may use cookies to serve ads based on your prior visits to this and other websites. You can opt out of personalized advertising by visiting Google Ads Settings.
Third-Party Privacy Policies
The following third-party policies govern how each service handles data. We encourage you to review them:

By using this website, you consent to this privacy policy and the data practices described above. If you do not agree with any part of this policy, you should disable cookies in your browser or avoid using the site.
