Entradas de la calculadora
Los valores de la calculadora se procesan en su navegador. No los enviamos a un backend, no los guardamos en una cuenta ni los incluimos en análisis. Cerrar o recargar la página restablece la entrada no guardada a menos que haya abierto una URL compartida.
Enlaces compartidos e informes descargados
Al elegir Compartir se crea un fragmento de URL que contiene los valores que ingresó. Cualquiera que reciba ese enlace puede leer esos valores. Comparta enlaces únicamente con las personas que desea que los vean. Las exportaciones CSV se generan localmente y se guardan en su dispositivo.
Cookies, hosting y terceros
ShopMathLab uses Google Analytics to understand how visitors use this site. Google Analytics sets cookies and collects information such as pages viewed, approximate location and device type; IP addresses are anonymized before storage. We do not use this data to identify individual visitors, and calculator inputs are never included in it. The hosting service may separately process routine request information, such as IP addresses and browser details, to deliver and protect the website. External source links take you to sites governed by their own privacy policies.
Your choices
Most browsers let you block or delete cookies through their settings, and browser extensions can block analytics scripts entirely. Doing so does not affect any calculator's functionality, since calculations always run locally in your browser regardless of analytics.
