What stays home, and what leaves

Walter lives on a computer you own. We don't run a cloud that stores your conversations. But an AI that thinks has to send words somewhere, so here is exactly where they go.

Stays on your device

Leaves your device

Goes toWhatWhen
Anthropic (Claude), the AI brain you chooseThe words of your requests, the memory notes it needs, and anything it reads for you (a calendar entry, an email, a web page)Every time it thinks. Under your own Claude plan or API key and Anthropic's terms and settings, not ours.
OpenAIAudio or text for cloud speechOnly if you switch on cloud speech with your own key. Off by default; a small cloud mark shows on the face while it's used.
GoogleCalendar, mail or files you allowOnly if you connect an account. Mail is read when you ask; drafts are never sent without your yes.
CloudflareEncrypted phone-app traffic to your WalterOnly if you use remote access (Cloud Link or your own tunnel).
Weather, sports, podcast and video servicesYour approximate location for weather, team names, search termsWhen those features run.
UsNothing by default. Your waitlist answers; later, only what you choose to send for supportWhen you sign up or ask for help.

What we never do

Being honest about the trade-offs

Walter is an AI agent that can run programs on its own computer and read things like web pages and email. Text on a page or in an email can try to trick an AI. That's why Walter gets a dedicated machine, asks for your spoken yes before spending money, sending messages or touching locks and alarms, and why admin access starts switched off. A more restricted permission mode is planned before public launch.
