Private by Design
No account, ads, tracking, third-party analytics, or developer-operated backend. Your work stays on your device unless you deliberately share or export it.
Use It Responsibly
Engineering results are planning aids. Verify refrigerant properties, field measurements, equipment limits, and applicable codes before making service or design decisions.
