The browser extension collects nothing and makes no network requests. This website counts anonymous visits and button clicks (for example, how many people calculate a score) with a cookie-free analytics tool we host ourselves. We never see or store the text you type: your prompt is scored in your browser and stays there. No account. Read the privacy policy.

L’estensione per il browser non raccoglie nulla e non fa richieste di rete. Questo sito conta in forma anonima visite e clic sui pulsanti (per esempio quante persone calcolano un punteggio) con uno strumento di statistica senza cookie, ospitato da noi. Non vediamo e non salviamo mai il testo che scrivi: il prompt viene valutato nel tuo browser e lì resta. Nessun account.

La extensión del navegador no recopila nada y no hace solicitudes de red. Este sitio cuenta de forma anónima visitas y clics en botones (por ejemplo, cuántas personas calculan una puntuación) con una herramienta de estadísticas sin cookies, alojada por nosotros. Nunca vemos ni guardamos el texto que escribes: tu prompt se puntúa en tu navegador y se queda ahí. Sin cuenta.
