Terms of Service

Who operates CarbEngine

Sweltr LLC operates CarbEngine.

These Terms are governed by the laws of Missouri, without regard to conflict-of-law rules.

Current product scope

The free calculator is available without login or payment. A paid Pro version is planned, but Pro early access is currently mailto interest only until a real paid feature ships.

The current launch scope is limited to users in the United States.

Beta status

CarbEngine is in beta. Calculator outputs, pricing snapshots, supplier recommendations, and planned features may change as the product is tested and improved.

The calculator flow remains free first: recipe results and shopping options appear before the optional recipe email request.

No guaranteed outcomes

CarbEngine can estimate fueling and cost scenarios, but it cannot guarantee performance, tolerance, availability, pricing, or results.
