Multivac is a desktop app with no backend of ours behind it. There is no account to create and nothing to log into. The short version: your chats, keys, and settings live on your computer, and the only thing that leaves is the request you send to a model provider you picked.

Nothing. Multivac has no analytics, no crash reporting, and no usage tracking. We do not run a server that your app talks to, so there is no log of who you are or what you ask. We could not see your conversations even if we wanted to.
Your conversations, folders, and preferences sit in a local SQLite database on your machine, under your home directory. You can open it, back it up, copy it to another computer, or delete it. It is your file.
API keys are kept in your operating system’s own keystore: Keychain on macOS, Credential Manager on Windows, and libsecret on Linux. Multivac reads a key when it needs to make a request and does not copy it anywhere else.
When you send a prompt, Multivac calls the provider you chose directly: Anthropic, OpenAI, Google, Mistral, and so on, or a local model that never leaves your computer at all. The request goes from your device to that provider over their API. There is no Multivac proxy in the middle reading or storing it.
Once a request reaches a provider, that provider’s own privacy policy and data-retention rules apply to it. We have no control over how Anthropic or OpenAI handle the text you send them, so it is worth reading their terms for the models you use.
If you run a model through Ollama or another local endpoint, the prompt and the response never touch the network. Everything happens on your hardware.
This site has one form: the early-access signup. If you enter your email there, we store it so we can send you a download link when Multivac ships, and nothing else. We will not sell it or hand it to anyone. Ask us to remove it and it is gone.
If this policy changes, the date at the top changes with it. Since the app keeps no contact details for you, the current version here is always the one that applies.
