1. The short version
Refreal is sold as a one-time purchase through Polar.sh, who acts as merchant of record for the transaction — payment, invoicing, taxes, and refunds are handled under Polar's own Terms of Service. These Terms cover the software itself and what you're licensed to do with it.
2. What you're buying
A one-time license to the Refreal source code — see the License page for exactly what that covers. No subscription, no recurring charge.
3. No warranty
Refreal is provided "as is", without warranty of any kind. You're responsible for testing it in your own environment before relying on it in production.
4. Contact
Questions about the software itself (not billing — that's Polar) via contact link.
