| Data | Where it lives | Your control |
|---|---|---|
| App and plugins | Your machine, in ~/.gloomberb or GLOOMBERB_HOME | Yours |
| Passwords, API keys, broker logins entered in the app | Your device only | Never synced |
| Layouts, watchlists, portfolios, notes, settings | Your machine, and Gloom Cloud once you sign in | Stay signed out to keep them local |
| Team content | Gloom Cloud, visible to the team | Broker-linked portfolios cannot be shared |
| Crash reports and usage counts | Gloom's API. Nothing from your workspace. | One setting each, or GLOOMBERB_NO_TELEMETRY=1 |
| Command-bar searches | Your account, when you are signed in | Off with Usage Counts |
| Ask Gloom and AI features | Your question and the data it reads go to a model provider | The BYOK AI plugin's panes use your own provider |
| Servers | Finland. The company is in Hong Kong. | Processors are listed in the privacy policy |
Exception: connect a broker in Gloom Cloud for MCP use and Gloom holds that connection, with tokens encrypted at rest. We do not use your workspace or conversations to train AI models.
