Privacy Policy
1. Introduction
Welcome to the ASIC ROI Calculator, a free, open-source, static web utility designed to help cryptocurrency miners evaluate the profitability of ASIC mining hardware ("we," "us," or "our"). This Privacy Policy explains our data practices when you use our tool, which allows entry of parameters like hardware cost, hash rate, power consumption, electricity rate, coin price, block reward, and network hashrate to compute break-even time and ROI metrics.
We prioritize user privacy above all. The calculator operates entirely client-side in your browser—no data is transmitted to any server. This means we do not collect, store, or process any personal information. All inputs and calculations remain on your device, ensuring complete confidentiality.
2. Information We Do Not Collect
As a fully static tool hosted on platforms like GitHub Pages, we collect zero data. Specifically:
- No Personal Data: Names, emails, IP addresses, or location information.
- No Usage Analytics: We do not track visits, page views, or interaction patterns.
- No Input Data: Your entered values (e.g., ASIC specs or coin prices) are processed locally and never sent anywhere.
- No Cookies or Trackers: No cookies, local storage persistence, or third-party scripts for monitoring.
Everything happens in your browser's memory during the session.
3. How the Tool Functions
The ASIC ROI Calculator uses pure JavaScript to perform calculations instantly:
- Local Processing: Formulas for daily revenue (based on hash share), power costs, and break-even are executed on your device.
- No External Calls: Beyond loading Bootstrap CSS/JS from CDNs (which do not track users), no network requests occur.
- Temporary Data: Any reactive state is held in browser memory and cleared on refresh.
This architecture guarantees absolute data isolation.
4. Third-Party Services
We use only Bootstrap via public CDNs for styling—these load static files without tracking. No analytics, advertising, or data-sharing services are integrated.
5. Security and Your Responsibility
Since no data leaves your device, security risks are minimal. However:
- Use updated browsers for best protection.
- Avoid public computers for sensitive calculations.
6. Children's Privacy
The tool is not directed at children under 13. We do not knowingly collect any data from minors.
7. Compliance and Changes
Our no-collection approach complies with GDPR, CCPA, and similar laws by default. We may update this policy—changes will appear here with the new effective date.
