Privacy Policy

Effective Date: December 26, 2025

1. Introduction

Welcome to the GPU Mining ROI Tool, a completely client-side web application designed to help cryptocurrency miners accurately calculate hardware profitability and payback periods. This Privacy Policy explains our approach to user privacy. We prioritize complete data isolation and operate under a strict no-collection principle. All calculations occur entirely within your browser, and no information is ever transmitted to us or any third party.

2. Information We Do Not Collect

The tool is built to function without gathering any data from users. Specifically, we do not collect:

  • Personal Information: Names, email addresses, IP addresses, or any identifiers.
  • Usage Data: Browser details, device information, location, or session analytics.
  • Input Data: Hardware costs, hash rates, power consumption, electricity rates, reward estimates, or any advanced parameters you enter remain exclusively on your device.
  • Tracking Data: No cookies, local storage persistence, analytics scripts, or tracking pixels are used.

Since everything processes locally via JavaScript, your inputs never leave your browser.

3. How the Tool Operates

All functionality is client-side only:

  • Inputs are processed in real time using pure JavaScript calculations.
  • Results, breakdowns, and profitability projections are generated instantly in your browser.
  • URL parameters are used solely for sharing calculation states and are not logged or stored.
  • No server requests are made beyond loading the static application files.

This architecture ensures absolute privacy even when handling sensitive financial planning data.

4. Third-Party Services

We do not integrate any external analytics, advertising, or tracking services. The application uses only static assets and Bootstrap via CDN for styling, which do not collect personal data. Any external libraries are loaded without tracking capabilities.

5. Data Security

Because no data is transmitted or stored by us, traditional server-side security concerns do not apply. Users are encouraged to maintain secure browsing habits, use updated browsers, and avoid sharing URLs containing sensitive calculation parameters if privacy is a concern.

6. Changes to This Policy

We may update this Privacy Policy periodically. Changes will be reflected on this page with an updated effective date. Continued use of the tool constitutes acceptance of the current policy.

7. Contact

Questions about this Privacy Policy can be directed through our public repository or community channels.

Your mining calculations remain 100% private — exactly as intended.
