1. Introduction & Overview
Welcome to ZU Mining (zumining.com). We respect your personal privacy and are committed to protecting information collected through your use of our cryptocurrency mining profitability calculators, hardware benchmark directories, and educational resources.
This Privacy Policy explains how information is collected, used, and safeguarded when you visit ZU Mining, and outlines your rights and choices regarding your personal data in compliance with applicable data protection laws and official third-party advertising requirements.
2. Information We Collect
ZU Mining does not require user registration or account creation to access any of our public tools, calculators, hardware directories, or educational guides. We collect only the following limited categories of information:
- Voluntarily Provided Information: When you submit a message through our Contact Us or Advertise With Us forms, we collect your name, email address, company name (if provided), subject, inquiry category, and message text solely to respond to your inquiry and provide status updates.
- Calculator & Rig Builder Inputs: Inputs entered into our interactive calculators — such as hashrate, power consumption in Watts, local electricity costs ($/kWh), and pool fee percentages — are processed client-side in your browser or transiently in memory to calculate profitability metrics. These parameters are not associated with personal identities or user profiles.
- Standard Server Log Files: Like standard web platforms, our servers automatically record basic technical metadata when you access pages. This may include your Internet Protocol (IP) address, browser type and version, operating system, referring/exit pages, date/time stamps, and requested resource paths. This information is used strictly for server maintenance, DDoS mitigation, security monitoring, and diagnostic troubleshooting.
3. Cookies and Similar Technologies
Cookies are small text files placed on your device by your web browser. ZU Mining uses cookies and browser local storage strictly for functional purposes and third-party advertising:
- Essential & Preference Cookies: We use first-party session cookies (such as CSRF security tokens to protect contact forms against unauthorized submissions) and browser local storage to save your calculator preferences (such as selected hardware models or electricity cost settings) locally on your device for your convenience.
- Advertising Cookies: Third-party advertising partners, including Google, may place or read cookies on your browser when advertisements are displayed on our website.
4. Third-Party Advertising & Google AdSense
ZU Mining may display third-party advertisements served by Google AdSense and other third-party advertising networks to help fund server operations, ongoing development, and live blockchain API telemetry.
In accordance with official Google publisher policies and advertising requirements, we disclose the following:
- Third-Party Vendor Cookies: Third-party vendors, including Google, use cookies to serve advertisements based on a user's prior visits to ZU Mining or other websites across the Internet.
- Google Advertising Cookies: Google's use of advertising cookies (including the DoubleClick cookie where applicable) enables it and its advertising partners to serve relevant ads to our visitors based on their visit to ZU Mining and/or other sites across the World Wide Web.
- Personalized Advertising Controls & User Opt-Out: Users may opt out of personalized advertising by visiting Google's official Google Ads Settings or by visiting Google Ad Personalization Controls.
- Industry Opt-Out Platforms: Alternatively, users can opt out of a third-party vendor's use of cookies for interest-based advertising by visiting the Network Advertising Initiative (NAI) opt-out page or the Digital Advertising Alliance at AboutAds.info Choices (for US users) or Your Online Choices (for European users).
5. Analytics & Performance
We may monitor aggregated, non-personally identifiable traffic metrics (such as page view counts, popular coin calculators, and device types) to evaluate platform performance, optimize server response times, and improve user experience. These metrics do not track individual users across unrelated third-party websites.
