Marshal Stack is a console for infrastructure you run yourself. It connects to a Mac agent and a relay server that you operate. We do not host your projects, your code, or your sessions.
All application traffic goes to the relay server address you enter in Settings. That server is yours. The app sends:
Nothing is sent to any server operated by us, because the app has no server of ours to talk to.
Nothing from the app. Marshal Stack contains no analytics, advertising, attribution or crash reporting SDKs. There is no account to create and no profile to build.
The studio page has a form that asks for an email address. If you submit it, that address — with the page language and a timestamp — is sent to our relay server and stored there, so that we can write back to you about the studio. It is used for nothing else: no newsletter, no profiling, no sharing with third parties. Ask us and we will delete it.
If you use voice input, speech is processed by Apple's speech recognition on your device or through Apple's services, under Apple's privacy terms. The resulting text is sent only to your own relay.
Notifications are delivered through Apple Push Notification service. Apple handles them under its own privacy policy. Your push token is stored on your relay server so it can reach your devices; you control that server and can delete the token at any time by removing it there or deleting the app.
Because your relay and Mac agent are yours, retention is entirely under your control. Deleting the app removes its local settings from your device.
Marshal Stack is a developer tool and is not directed at children under 13.
If this policy changes, the updated version will be posted on this page with a new date above.
