Privacy Policy

Effective Date: December 17, 2025

1. Introduction

Welcome to the In-Depth Crypto ROI Calculator, a completely client-side web utility designed to help cryptocurrency investors accurately measure returns, analyze risk, and plan strategies. We prioritize your privacy above everything else. This tool operates entirely in your browser, meaning no data is ever collected, stored, or transmitted to any server. This Privacy Policy explains our commitment to protecting your information through a strict no-collection approach.

2. Information We Do Not Collect

The calculator is built with privacy as the core principle. We do not gather any information from users, including:

  • Personal data: Names, email addresses, IP addresses, or any identifiers.
  • Investment details: All inputs such as purchase prices, quantities, fees, or holding periods remain exclusively on your device.
  • Usage analytics: No tracking of page views, feature usage, or session duration.
  • Simulation data: Monte Carlo results and other calculations are processed locally and never shared.

Because everything runs client-side using JavaScript, your sensitive financial scenarios stay private by design.

3. How the Tool Operates

When you use the calculator:

  • All processing happens locally: ROI calculations, breakeven analysis, target planning, and Monte Carlo simulations execute directly in your browser.
  • No server communication: Inputs are never sent over the internet to us or any third party.
  • Local storage is optional and temporary: Saved calculations use your browser’s localStorage only for convenience and are cleared when you choose.

This architecture ensures complete data isolation—we have no access to your information at any point.

4. Third-Party Services

We do not integrate analytics providers, advertising networks, or external tracking services. The tool loads only necessary Bootstrap CSS/JS from a public CDN for styling and functionality, but these resources do not collect personal data or track usage.

5. Cookies and Tracking

The calculator does not use cookies, local beacons, or any tracking technologies. Your experience is completely stateless beyond optional local storage for your own convenience.

6. Security and Responsibility

While we collect nothing, we recommend using the tool on secure, updated devices and browsers. Exported results or copied data become your responsibility once shared externally.

7. Changes to This Policy

We may update this Privacy Policy occasionally. Changes will be reflected here with the new effective date. Continued use constitutes acceptance of the updated terms.

Your privacy is built into the foundation of this tool—zero data collection, always.
