Architecture & Privacy

Morrow is engineered with strict local sovereignty.

1. Network Boundary

Morrow only opens an HTTP client connection to the configured Ollama endpoint (default: http://localhost:11434).

• Zero Telemetry: No tracking, usage analytics, error pings, or background metrics.
• Zero Third-Party Accounts: No sign-in, API keys, or cloud accounts.
• Local Network Support: You can point Morrow to an Ollama server running on your home LAN via /url http://192.168.1.x:11434.

2. Storage Engine

Morrow uses embedded SQLite (via rusqlite bundled) with WAL (Write-Ahead Logging) enabled.

Database Location

~/.local/share/morrow/history.db

Schema Design

• sessions: Stores session UUID, title, active model, creation timestamp, and update timestamp.
• messages: Stores message UUID, session reference, role (user, assistant, system), text content, and timestamp.

3. Ephemeral Mode

When enabled via /temp on:

• Chat messages reside in volatile RAM only.
• SQLite writes are completely disabled for the duration of the ephemeral session.
• Exiting Morrow or clearing the session discards all ephemeral memory.
