Cloud sync¶
Screenshot placeholder — Cloud sync settings with connected devices list.
Real-time sync over the Voltius relay. Pro and Teams plans.
How it works¶
- Sign in with your Voltius account (created on app.voltius.app or in-app).
- The desktop derives
enc_key(Argon2id + HKDF-SHA256) from your password. - CRDT payloads are encrypted with
enc_keyand pushed over an SSE channel to the relay. - Other devices subscribed to your account receive and merge in real time.
The relay sees ciphertext only — see Security → Sync protocol.
Sign in¶
Settings → Account → Sign in.
| Field | Notes |
|---|---|
| Your Voltius account | |
| Password | Used to derive both auth_key (server login) and enc_key (vault) |
If you don't have an account yet, Create account from the same screen.
What syncs¶
- Hosts, folders, tags
- Identities, keys, known hosts
- Snippets, port-forwarding rules
- App preferences such as theme, UI scale, list/grid layouts, and sort modes
Most user data and preferences are included in sync. Device-specific runtime state, such as currently open terminals, is not.
Trade-offs¶
| Pros | Cons |
|---|---|
| Real-time | Paid plan |
| Multi-device, multi-vault | Requires account |
| Audit logs (Teams+) | — |
Self-host the relay
