Does the app need an account, subscription, or in-app purchase?
No. It is a one-time paid download with no account, advertising, analytics, subscription, or in-app purchase.
Does it work offline?
Yes. Core features and bundled material work without a developer-operated service.
Where is my information stored?
Your editable workspaces, parameter values, imported records, comparison settings, notes, and export history remain in local app storage.
What are the limits?
Screening model. Validate pump curves, outgassing, seals, temperature, gas species and transitional-flow behavior for hardware decisions.
Email support@shadowfetch.com with the app name, device model, iOS version, and a concise description of the issue.
