Privacy Policy
At ZU Calculator, we take your privacy seriously. This Privacy Policy outlines how we collect, use, and protect your information when you use our website.
Client-Side Calculations & Data
The core functionality of ZU Calculator is designed to protect your privacy. Most of our calculators process your inputted numbers client-side (directly within your own web browser). This means that the specific financial, health, or personal values you type into the calculators are generally not transmitted to, processed by, or stored on our servers. For features that do require server processing, we do not permanently store your input data unless specifically stated.
Information We Collect
We do not require you to create an account or provide personally identifiable information to use our standard calculators. Like most websites, our server automatically logs basic, non-personally identifying information that web browsers and servers typically make available. This includes your browser type, language preference, referring site, and the date and time of each visitor request, as well as IP addresses. This data is collected solely for security, administration, and maintaining the operational health of our platform.
Cookies, Web Beacons, and Consent
ZU Calculator uses cookies (small text files stored on your device) and web beacons to help us analyze website traffic, remember your preferences, and improve our services. Depending on your region, you may be presented with a Consent Management Platform (CMP) dialog when you first visit our site. This tool allows you to control which cookies are active and manage your preferences regarding personalized advertising. You can review or revoke your consent at any time using your browser's standard settings or our privacy controls.
Advertising and Google AdSense
To keep ZU Calculator free for everyone, we use third-party advertising companies, including Google AdSense, to serve ads when you visit our website. These companies may use information about your visits to this and other websites in order to provide advertisements about goods and services of interest to you.
- Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to ZU Calculator or other websites.
- Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to our site and/or other sites on the Internet.
- Depending on your region and consent choices, you may be served personalized or non-personalized advertisements.
Your Choices Regarding Personalized Advertising
Users may opt out of personalized advertising by visiting Google's Ads Settings. Alternatively, you can opt out of a third-party vendor's use of cookies for personalized advertising by visiting www.aboutads.info.
You can also choose to disable cookies entirely through your individual browser options. However, doing so may affect your ability to use certain features on our website.
Google Analytics
When enabled, we use Google Analytics to collect usage and interaction data to understand how visitors interact with our layout and which tools are most popular. This data includes device and browser types, pageviews, and general geographic location (derived from IP addresses). We use this information strictly to improve website performance and user experience, not to identify you personally. You can opt out of Google Analytics by installing the Google Analytics Opt-out Browser Add-on.
Changes to This Policy
We reserve the right to update or change our Privacy Policy at any time. Any changes will be posted on this page with an updated revision date.
