Your data stays on your machine.
VaporCalc runs entirely offline. No compound inputs, calculation results, or usage patterns are transmitted to any server.
Local execution, no telemetry
All calculations run on your local machine. No compound names, CAS numbers, temperature ranges, or plot outputs are ever sent to VaporCalc servers or any third party.
Optional crash reporting
The app can send anonymous crash logs to help fix bugs. This is opt-in and disabled by default. You can toggle it at any time in Preferences. Crash reports contain no compound data.
Purchase and license contact data
If you purchase a license, we collect your name and email address. That information is used only to deliver your license key and respond to support requests. It is never sold, rented, or shared with third parties.
