Local-first mode

Your data lives on your device. Cloud is opt-in per surface.

What it is

osFoundry runs as a real desktop app. Your notes, chats, files, model weights and chunks live on your machine first. The cloud is an opt-in mirror — never the source of truth.

When you go offline, everything keeps working. When you come back, a bi-directional sync engine reconciles. You decide per-folder whether to ever push to cloud at all.
