Clear local history
Erases the device vault, pending outbox, and topic read positions. It does not touch server history or another device.

device memory guide
What stays where.
Onyx is browser-portable, but it is not a blank window onto a server. It can remember useful context on this device. This map shows the boundary, the crossings you choose, and the controls that erase local state without pretending server history changed.

The boundary is the feature.
Each row names the local copy, the only crossing, and what remains independent on the other side.
- 01Search Center
- This device Searches loaded messages and the bounded local vault. Saved names, modes, and query text stay here.
- Explicit server search
- Connected server May search its archive for the active conversation when supported. Results are labelled separately.
- 02Reviewed anchors
- This device Small metadata anchors reopen the exact catch-up span you reviewed. They are not message copies.
- No automatic crossing
- Connected server Room history follows the server's own retention. Clearing an anchor does not erase that history.
- 03Topic positions
- This device Per-topic cursors remember a room or topic, message ID, and timestamp so navigation can resume precisely.
- Portable file, if chosen
- Connected server Does not need this local reading position. Messages and topic state remain separate from the cursor.
- 04Queued sends & drafts
- This device Offline channel sends, room drafts, channel-topic drafts, and DM drafts contain unsent text here.
- Send after reconnect
- Connected server Receives a queued send only when Onyx reconnects. Encrypted DMs are never queued as plaintext.
- 05On-device translation
- This device A supported browser model translates loaded text in the current view. Onyx marks the result as device-made.
- No external endpoint
- Connected server Receives neither the translation request nor its result. If the browser lacks a local model, Onyx says so.
- 06Encrypted-DM search
- This device Decrypted plaintext exists only in transient loaded state. Search can match that visible text locally.
- Query stays here
- Connected server Stores and relays ciphertext, not searchable plaintext. Onyx blocks server search for encrypted DMs.
MEDIA This guide covers app memory. Live voice and video use the LADON/Ophion media path; they are not copied into the local message-history vault.
A transfer crosses device to device.
Preferences → Portable vault creates a JSON file only when you ask. You review a file again before importing and merging it on another Onyx device.

The reviewed file can include
- bounded vault-safe history; encrypted DMs remain ciphertext
- reviewed anchors and topic read positions
- room drafts and channel-topic drafts
- followed rooms/topics and saved Search Center queries
- saved sign-in targets, retention policy, and Preferences switches

Clear the thing you mean.
Preferences exposes separate, confirmed controls. Each one verifies local storage before reporting success.
Clear reviewed anchors
Removes only remembered review points; messages and topic cursors remain.
Clear all saved searches
Removes saved names, modes, and query text without erasing message history.
Clear topic read positions
Removes per-topic cursors only; room messages and server history remain.
Discard local drafts
Removes room and channel-topic drafts. Direct-message drafts stay unless you edit or send them.
Discard queued sends
Removes offline queued text before reconnect so it cannot be sent later.
Find every control: open Onyx → Preferences → Search & history. Turning off Remember conversations on this device also clears the local vault.

Private search has a hard stop.
For ordinary room history, Search Center can show device results and a separately labelled server archive lane. For an encrypted DM, Onyx does not send the query across the boundary. The server has ciphertext; the current device can search only plaintext already decrypted in memory.
