Privacy

The short, honest version:

• No accounts, no sign-up.We don't know who you are and don't need to.
• Calculations happen in your browser for simple math. Nothing is sent anywhere.
• AI features send only what you type(your bill description, a country name) to our server, which forwards it to Anthropic's Claude API to generate the answer. We don't store these requests beyond short-lived operational logs, and we never sell them. Don't include names or details you wouldn't want processed.
• Anonymous usage counters (page views, which features get used) help us decide what to build. No cross-site tracking, no advertising identifiers, no fingerprinting.
• Rate limitinguses your IP address transiently to prevent abuse; it isn't stored long-term or joined to anything.

If this policy changes materially, this page will say so with a date.
