Privacy Policy

Data Collection

EquationCraft is designed with privacy as a core principle. We collect minimal data:

  • No personal information: We do not collect names, emails, or any personally identifiable information.
  • No user accounts: No registration or login required.
  • Local storage only: Your calculation history and preferences are stored locally in your browser using IndexedDB. This data never leaves your device.

Analytics

We use Ahrefs Web Analytics for basic site usage statistics. This is a privacy-friendly analytics service that:

  • Does not use cookies
  • Does not track users across websites
  • Collects only aggregate, anonymous data about page views and referrers

Cookies

EquationCraft does not use cookies for tracking. Your browser's local storage is used only to save your calculation history and preferences on your device.

Third-Party Services

We do not share any data with third-party services. All calculations are performed entirely in your browser using open-source JavaScript libraries.
