Security
Local-first by default. Cloud features are opt-in.
Cosmos touches sensitive developer data, so the security model starts with a simple promise: indexing and memory run on your Mac by default, and source code is not uploaded just to make the app useful.
- Default mode
- On-device indexing and local storage
- Cloud backup
- Optional Pro feature
- Transport
- TLS for cloud backup and billing flows

What Cosmos indexes
- Project files, symbols, call relationships, docs, notes, and error+fix lessons from folders you choose.
- Terminal/runtime problems captured inside Cosmos when you run projects from the app.
- Metadata needed to route MCP tool results back to the right project scope.
What stays local
The code-aware index, memory database, and lessons are stored on the device by default. Connected AI tools query Cosmos over the local MCP bridge and receive bounded context instead of a full repo dump.
What is never uploaded by default
- Your source code.
- Your local notes and private folders.
- Your full codebase index.
- Terminal output from projects unless you explicitly use a flow that sends context to an AI tool.
Cloud backup
Pro backup is planned as an opt-in feature for encrypted backup, daily auto-backup, and restore. The local tier remains usable without cloud backup.
Delete data
You can remove indexed folders and local data from inside Cosmos. For account, waitlist, or billing-related deletion requests, contact the support address listed on this site.
