Runs on your Mac
The core sizing, injector and nozzle workflows, reporting, and export run locally on Apple silicon Mac. There is no cloud requirement for the core engineering workflow and no browser-based engineering state.
Security & local data
A local desktop workflow, by design.
RPL Engine Workbench is a native Apple silicon Mac application. The core sizing, geometry, reporting, and export workflows run on your machine, and your project files stay where you save them.
Your files stay local
Project cases, PDF reports, DXF geometry, images, videos, and other exports are written to local disk locations you choose. They are not uploaded to Rocket Propulsion Lab as part of the core workflow.
Trial and licensing
Trial mode is built into the app. No license key is required to start trial mode. Paid licenses unlock the purchased tier through the license path; license activation and periodic validation may communicate with Freemius, and license credentials are stored locally using the app's configured storage path.
Optional local integrations
Optional tools such as RocketCEA through a local Python environment and ffmpeg for MP4 export are local integrations that you install and configure. When used, they run on your machine.
What this page is and is not
This describes the current public build at a high level; it is not a formal security certification or a penetration-test report. For organization-specific security review, contact support@rocketpropulsionlab.net.
Website
This website collects only what you send.
The marketing site is separate from the desktop application. Download, licensing, and contact requests are made through normal links, email, or Freemius checkout. This website does not currently load advertising trackers. See the privacy page for details.
