Privacy Policy & GDPR

1. Overview

MCF.DIGITAL ("we," "us," "our") respects your privacy. This Privacy Policy explains what information we collect, how we use it, and your rights, including rights under the EU General Data Protection Regulation (GDPR) and the California Consumer Privacy Act (CCPA).

2. Information We Collect

2a. Information You Provide

• Contact information: Name and email address if you submit the contact or lead form.
• Calculator inputs: Gas volumes, compositions, financial parameters you enter into our tools.

2b. Automatically Collected

• Usage data: Pages visited, features used, session duration (via privacy-respecting analytics).
• Device information: Browser type, operating system, screen resolution.
• IP address: Collected for security and rate-limiting purposes only.

3. Data Processing — Client-Side First

All calculator computations run entirely in your browser. No calculation inputs or outputs are transmitted to our servers unless you explicitly choose to save a report. This "client-side first" architecture minimizes data exposure by design.

4. How We Use Your Information

• To respond to contact form submissions and support requests.
• To improve Platform features and user experience.
• To generate aggregate, anonymized analytics (never sold to third parties).
• To comply with legal obligations.

5. Legal Basis for Processing (GDPR)

For users in the European Economic Area (EEA), we process personal data under the following bases:

• Consent: When you submit a form or opt into communications.
• Legitimate interest: For analytics and Platform improvement, balanced against your privacy rights.
• Legal obligation: Where required by applicable law.

6. Your Rights

Under GDPR, CCPA, and similar regulations, you have the right to:

• Access — Request a copy of all personal data we hold about you.
• Rectification — Correct inaccurate personal data.
• Erasure ("Right to be Forgotten") — Request deletion of your personal data.
• Portability — Receive your data in a structured, machine-readable format.
• Objection — Object to processing based on legitimate interest.
• Withdraw consent — At any time, without affecting prior processing.

To exercise these rights, contact us via our contact page. We will respond within 30 days.

7. Cookies & Local Storage

The Platform uses localStorage to save your calculator preferences and saved reports on your device. We do not use tracking cookies. If third-party analytics are enabled, they use privacy-respecting, cookie-free tracking methods.

8. Data Retention

Contact form submissions are retained for 24 months, then deleted unless an ongoing business relationship exists. Calculator data stored in your browser persists until you clear your browser data; we have no server-side copy.

9. Third-Party Services

We may use third-party services for:

• Market data APIs (cryptocurrency prices, network statistics)
• Hosting and content delivery
• Privacy-respecting analytics

These services have their own privacy policies. We do not sell, rent, or trade your personal information to any third party.

10. Data Security

We employ industry-standard security measures including HTTPS encryption, access controls, and secure hosting. However, no method of electronic transmission or storage is 100% secure; we cannot guarantee absolute security.

11. International Transfers

If your data is transferred outside the EEA, we ensure adequate safeguards are in place (e.g., Standard Contractual Clauses) in compliance with GDPR Chapter V requirements.

12. Children's Privacy

The Platform is not directed at individuals under 18. We do not knowingly collect personal information from children. If you believe we have inadvertently collected such data, please contact us for immediate deletion.

13. Changes to This Policy

We may update this Privacy Policy periodically. The "Last updated" date at the top reflects the most recent revision. Material changes will be communicated via a notice on the Platform.
