When you're signed in, Rumus quietly keeps your settings consistent across the devices where you use the app. The mental model: **anything that isn't a credential or a device-specific binary** syncs. Credentials and the like sync separately, encrypted, via the [vault](/docs/account/vault-sync). ## What syncs | Category | Included | | ----------------------- | ------------------------------------------------------------------------------------------------------- | | **Appearance** | Theme, accent color, terminal palette, language, terminal font (family, size, line height) | | **Keyboard shortcuts** | Every custom binding | | **Privacy preferences** | Telemetry / crash report toggles, sync toggles | | **AI settings** | Smart-autocomplete on/off, todo-list toggle, auto-collapse, max mode, **command whitelist / blacklist** | | **Rules & skills** | Both lists, including enabled state, with tombstone deletes for proper propagation | | **Workspace settings** | Workspace-level configuration (separate sync type) | Anything you set on one signed-in device shows up on the others on the next sync. ## What doesn't sync | Category | Why | | ---------------------------- | ------------------------------------------------------------------------------------------------------ | | **Custom AI models** | Stored locally because they're security-sensitive (API keys live in the vault, not in synced settings) | | **Local terminal profiles** | Device-specific — paths to shells differ across machines, WSL distros differ, etc. | | **Conversation history** | Local to each device today | | **Tabs and open workspaces** | Live state, not configuration | If you want the same custom model on a second device, add it there with the same key. If you want the same profile, recreate it. ## When sync runs Sync runs: * **At sign-in** — pulls down whatever the cloud has and reconciles with local. * **Periodically in the background** — currently every \~30 minutes for profile refresh. * **On demand** — there's a **Sync Now** button in **Settings → Privacy → Sync** (or the equivalent panel where the sync toggles live). The header / settings shows a **last sync time** so you know whether you're up to date. ## Conflict resolution Most settings sync is per-field with a "newest wins" merge — if you change theme to Dark on your laptop and accent color to Green on your desktop, both changes take effect after sync. For rules and skills (which are lists), Rumus uses **soft delete tombstones** so deletions from one device propagate cleanly without resurrecting items from a stale snapshot on another. The harder cases — vault data conflicts where two devices made changes to the same encrypted item — are handled differently; see [Vault sync & recovery](/docs/account/vault-sync). ## Turn sync off If you'd rather not sync at all, **Settings → Privacy → Sync** has toggles for each sync category. Turning a category off: * Stops pushing changes from this device. * Stops pulling cloud changes onto this device. * Doesn't delete anything that's already in the cloud — it just isolates this device. You can turn sync back on later; the next sync reconciles whatever's diverged. ## Telemetry and crash reports Adjacent to sync — and equally optional — Rumus can send anonymous telemetry and crash reports to help fix bugs and prioritize features. Toggles live in **Settings → Privacy**. Both are independent of sign-in: you can be signed in with telemetry off, or signed out with telemetry on. ## Privacy * Synced settings are sent to Rumus's API over TLS and stored on Rumus servers. * Settings are **not encrypted with your secret key** the way vault data is — they're configuration, not credentials. Don't put secrets into a rule or skill (use [vault-stored credentials](/docs/account/vault) instead). * Conversation history isn't synced today — it lives only on the device where you had the conversation. ## Next steps The separate, end-to-end-encrypted store for your secrets. How encrypted vault data flows between devices, and what to do on a fresh install.
