Your data

This page describes where things live and how to manage them. It is not a policy document. For the authoritative, complete statement of what Metroon does and doesn’t send anywhere, and why, see the privacy policy. Where anything below touches that question, treat the privacy policy as the final word and this page as a map to it, not a substitute for it.

Where things live

Metroon keeps everything it stores for you, your session history and your knowledge base, in a private data folder that belongs to the app, managed by macOS the same way any Mac app manages its own data. You won’t find it by browsing your Documents or Desktop, and it isn’t synced through iCloud. If you want to locate it directly, open Finder, choose Go > Go to Folder, and look inside your user Library for a folder whose name includes Metroon; macOS creates it the first time you open the app.

Local models, if you use them, are stored separately from your session data, since they’re large files downloaded once and reused across sessions rather than something that changes as you use the app.

What the knowledge base is

Every session adds to a running knowledge base. The claims and citations your Citizens produce as they deliberate are recorded automatically, during the session itself; anything you choose to save from Debrief is added on top of that. That knowledge base isn’t limited to your most recent session, it accumulates, and later sessions can draw on relevant parts of it, so a question you ask this month can benefit from work a past session already did. Saving a Debrief insight doesn’t decide whether a session leaves a record behind; it marks what you want to keep and carry forward.

Backing it up

Because Metroon’s data lives on your local disk in an ordinary, macOS-managed location, the simplest backup is the one you may already have: Time Machine, or any other whole-disk or whole-Mac backup tool, covers it the same way it covers everything else on your machine, with no separate export step required. If you’re moving to a new Mac, restoring from a Time Machine backup or a full Migration Assistant transfer brings your Metroon data across along with everything else.

Deleting it

Deleting the app itself, whether by dragging it to the Bin or using an uninstaller, doesn’t necessarily remove its data folder on its own, since that’s standard behavior for most Mac apps and not specific to Metroon. Back up anything you want to keep before removing either the app or its data.

A complete reset depends on the storage layout of the version you have installed, so we don’t publish generic delete-the-folder steps here. Contact Support for the current procedure.

What leaves your Mac

The short version: it depends on which Citizens you chose. A local Citizen processes your question entirely on your Mac and sends nothing anywhere. A cloud Citizen sends your question, and the relevant context for that request, to the provider whose API key you added, the same way any app built on that provider’s API would, governed by that provider’s own terms and retention practices for API traffic, not Metroon’s.

That’s the mechanism, not the policy. For what’s actually collected, why, how long anything is kept, and your choices around it, the privacy policy is the complete and authoritative source, and this page defers to it rather than restating it.
