What leaves your machine
A plain-English statement of exactly what Remux Cloud syncs, where it lives, and how to remove it.
Remux is local-first. By default everything stays on your machine — nothing is sent anywhere, and no account is required. Cloud sync is opt-in, per project, and Pro-only: it does nothing until you sign in and explicitly Promote a project to a Space.
What syncs (only for a promoted project)
- Its board: cards, columns, comments, links, and the lightweight project metadata.
- Its attachments (pasted images / snippets), stored content-addressed (deduplicated by SHA-256).
What never leaves your machine
- Your terminals: panes, layout, PTY processes, and scrollback.
- Runners and any machine-bound workspace state.
- The board of any project you have not promoted — every local project keeps working exactly as before, signed in or not.
Your local copy under ~/.remux/ always remains the source of truth and works fully offline; the cloud holds a replica that reconciles in the background.
Where it goes, and how it's protected
- Board data → MongoDB Atlas, region EU (EUROPE_WEST), a third-party (MongoDB-managed) service.
- Attachments → Azure Blob Storage, region UK South.
- Both sit entirely behind the API: every request is authenticated with your account token, gated to Pro, and scoped to your Space — a token for one Space can't read another's data. Attachment bytes are proxied through the API (the storage account is never exposed publicly). Transport is HTTPS.
When it's sent
Only after you (a) sign in and (b) Promote a project. From then on the project's board syncs in the background on a gentle interval, when the app regains focus, when you open the project, and via a realtime nudge when another of your machines changes it. Signing out stops syncing and hides cloud projects from the sidebar; the local replica is kept on disk.
How to stop syncing / remove your data
All of these are self-serve — no support ticket, no waiting.
- Stop syncing a project: Demote to Local (right-click the project) copies the latest board back to a plain local project and clears the cloud binding. Non-destructive: the local copy is complete, and the cloud copy is left in place (you can re-promote later).
- Delete a cloud project: Delete from Cloud (right-click the project) removes that project's cloud data — its board snapshots and attachments — and keeps a local copy (it demotes first, so you don't lose the board). The cloud project, its snapshots, and its attachment references are deleted immediately; attachment blobs no other project references are reclaimed by the daily GC sweep.
- Delete your account data: Settings ▸ Cloud ▸ Delete account data erases everything your account holds in the cloud — your Space and every cloud project, board snapshot, and attachment inside it — along with your sign-in (refresh tokens) and the account itself, then signs you out. It asks you to re-confirm (type your email, and re-enter your password if you use one) because it can't be undone. Your local boards under
~/.remux/are untouched. If you have an active Remux Pro subscription, cancel it first (Settings ▸ Cloud ▸ Manage subscription) — we won't delete an account that's still billing.
Deletion is scoped to your own Space on the server: every delete is filtered by the Space on your signed-in token, so it can only ever remove your data.
