Data & Storage
Everything about what Kognar keeps on this computer: how much space it uses, how to back it up, and how to wipe it.
Open Settings (Ctrl/Cmd+U) → Data & Storage.
Storage usage
A total figure with a breakdown bar showing how the space is divided:
| Item | What it holds |
|---|---|
| Conversations | Chat history and messages in the local database |
| Image cache | Generated and attached images kept on disk |
| Audit logs | Application logs used for diagnostics |
Backup & restore
Export All Data
Downloads a compressed backup to your Downloads folder:
kognar-backup-YYYY-MM-DD.msgpack.gz
The file contains:
- All conversations and their messages
- Projects, their instructions and their semantic-context preference
- Conversation-to-project assignments
- Your agents (built-in state and custom agents)
- App settings
Import Backup
Select a .msgpack.gz file — or a legacy .json backup from an older version — and confirm.
Importing overwrites project data, conversation assignments and agents. Existing conversations are not deleted; imported ones are merged in. Restored conversations keep their original creation and activity dates, so the sidebar groups them under the right time headings.
This export is a file you keep yourself. It is separate from Sync with mobile, which keeps an encrypted copy in the cloud so your phone and this computer stay in step. Both can be used at the same time.
Danger zone
Clear Cache
Removes temporary index and cache data, then rebuilds it. Useful when search results look stale or incorrect. No conversations or settings are touched.
Reset Application
Reset is permanent and irreversible. It deletes:
- All conversation history and messages
- All settings and preferences
- All projects and project instructions
- All custom agents and rules
- All local cache and index data
A confirmation dialog appears first. Export a backup before resetting if you might need the data later.
Where the data lives
Kognar stores data locally using a SQLite database plus an application settings file:
| Platform | Location |
|---|---|
| macOS | ~/Library/Application Support/kognar-chat-client/ |
| Windows | %APPDATA%\kognar-chat-client\ |
| Linux | ~/.config/kognar-chat-client/ |
