Privacy Notice

Data and services

The site uses Google Analytics to understand visits and usage in aggregate. Firebase supports authentication and the account and project data users choose to save. These services may use cookies or device identifiers according to their configuration.

Local storage

The site uses local storage for preferences such as language and appearance, recently used calculators, locally retained inputs, and app-installation state. Some data remains on your device and can be cleared through browser settings.

Accounts and projects

When you create an account or save a project, the account and project data needed for those features is processed. We do not state a fixed retention period or promise an automatic deletion process that is not implemented.

Future advertising

Advertising is not currently enabled. If it is enabled, this page and the preference settings will be updated to reflect the approved configuration. An advertising provider may then use cookies or identifiers for personalized or non-personalized advertising, subject to user choices and applicable requirements.

Your choices

Use “Privacy / Ad preferences” in the footer to review the current status. Future advertising requires a suitable external consent provider; the present local control is not a completed consent result. Browser settings also control local storage and cookies.
