Privacy Policy

Browser-based calculations

Simulations and calculations are still processed locally in your browser. To create an account, we only use Google sign-in.

Saved favorites

When you save a simulation to favorites, we store its name, calculator, and URL parameters in a database so they can be associated with your account.

Analytics

When configured, we use Google Analytics to measure visits and site usage. This service may process cookie identifiers, device information, and browsing data, as well as produce aggregated reports.

Cookies

We use cookies needed for authentication and preferences. When enabled, analytics and advertising services may also use cookies. You can manage cookies in your browser settings and, when a consent message is displayed, choose your preferences there.

Advertising

When advertising is enabled, we use Google AdSense. Google and other vendors may use cookies to serve ads based on visits to this and other websites. You can manage personalization and learn how these vendors use data through the links below.

Third-Party Services

We use Google for authentication, Google Analytics for analytics when configured, Google AdSense for advertising when enabled, and Vercel for hosting. These providers process data under their own privacy policies.

Changes

This policy may be updated occasionally. Significant changes will be communicated on the main page or on this page.
