Cookie Policy

Last updated: February 2026

1. What Are Cookies?

Cookies are small text files stored on your device when you visit a website. They help the site remember your preferences and understand how you interact with it. Similar technologies include localStorage and sessionStorage, which store data directly in your browser.

2. How We Use Cookies & Local Storage

MCF.DIGITAL uses a minimal approach to data storage. We prioritize your privacy by keeping all calculator data in your browser and avoiding third-party tracking cookies.

2a. Strictly Necessary (Always Active)

  • Cookie consent preference: Remembers whether you've accepted or declined cookies so you aren't asked repeatedly.
  • Session management: Essential for the Platform to function correctly.

2b. Functional (With Your Consent)

  • Calculator preferences: Saves your last-used inputs (gas volumes, miner models, financial parameters) so you don't have to re-enter them each visit.
  • Saved reports: Stores generated reports in your browser's localStorage for later reference.
  • UI preferences: Remembers sidebar collapsed/expanded state and other interface settings.

2c. Analytics (With Your Consent)

  • Usage analytics: If enabled, privacy-respecting analytics help us understand which calculators are most used and how to improve the Platform. These do not use third-party tracking cookies.

3. Third-Party Cookies

We do not use third-party advertising cookies. If you interact with embedded third-party content (e.g., Google Calendar booking links), those services may set their own cookies according to their respective privacy policies.

4. Managing Your Cookie Preferences

You can manage your cookie preferences at any time:

  • On this site: Use the cookie consent banner that appears at the bottom of the page. You can change your preference by clearing your browser's localStorage.
  • In your browser: Most browsers allow you to block or delete cookies through their settings. Note that blocking all cookies may affect Platform functionality (e.g., saved reports will not persist).

5. Data Stored Locally

The following data is stored exclusively in your browser and is never transmitted to our servers:

  • Calculator input values and configurations
  • Saved report snapshots
  • Cookie consent status
  • UI state preferences

You can clear all locally stored data at any time by clearing your browser's site data for this domain.
