Your data remains completely private. Sero operates with a strict local-first architecture where everything stays on your device.
All file indexing and processing occurs locally on your device. Your files never leave your Mac.
Files remain 100% under your control. No background uploads, no cloud syncing, no external connections for processing.
We do not collect usage data, analytics, or behavioral information of any kind.
We have no insight into how you use Sero, what documents you process, or what questions you ask. The application architecture prevents it.
Sero requires no account creation, login credentials, or personal information.
There is no way to identify you or link your usage to any account. You remain completely anonymous.
Embeddings—the numerical representations used for semantic search—are generated locally on your device and never transmitted.
Embeddings remain private to your device and can be deleted by uninstalling Sero or clearing app data.
Sero uses Ollama to download and run open-source AI models locally on your Mac.
All supported models are open-source and available on GitHub for inspection.
Sero may include links to external resources. These are informational only.
Sero never automatically contacts third-party services. Any external connection requires your explicit action.
