Privacy Policy
Your privacy is important to us. This policy explains how Calculaderia handles your data.
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
We use Google Analytics to understand how the site is used (pages visited, time spent). This data is anonymous and aggregated, not identifying individual users.
Cookies
The site uses essential cookies for authentication, language preference and, when configured, Google analytics. You can disable non-essential cookies in your browser settings.
Third-Party Services
We use Google for authentication and Vercel for hosting. We recommend consulting those services' privacy policies to understand how they handle data.
Changes
This policy may be updated occasionally. Significant changes will be communicated on the main page or on this page.
