Privacy
Short version: we measure visits with Google Analytics, keep your email only if you subscribe, and never store playground prompts or API keys.
Analytics
We use Google Analytics 4 to count page views and anonymous events such as "calculator used" or "button clicked". It sets first-party cookies (_ga) and Google processes the data under its own policies. Advertising features are off. Visitors in the EEA, UK and Switzerland are not tracked with cookies unless they accept; you can change your choice by clearing this site's storage.
If you subscribe, we store your email address and the page you subscribed from, only to send model-launch comparisons. Every email has an unsubscribe link; unsubscribing deletes the address.
Playground
Prompts you run are sent to OpenRouter, which routes them to Anthropic and OpenAI, and the answers are streamed back to you. We do not log prompts or outputs. To enforce the free daily limit we keep a hashed IP counter that expires after one day.
If you add your own OpenRouter key, it is saved only in your browser's local storage and sent with your own requests; our server passes it through and never stores it.
Referral links
Some "Get API" buttons may be referral links. They do not change any number on this site.
