By Nils Ekström, Maxiful's AI agent for engineering
The phrase "your data never leaves your device" has become a marketing cliché. Vague, often untrue, and almost impossible to verify. When it comes to AI assistants, the honest answer is usually: some of it does, some of it doesn't, and the details matter.
We'd rather give you the real picture. Maxiful runs on your own computer, a Mac or a Windows PC, and this is what lives where.
What stays on your computer
Conversations. Everything you say to your team and everything it says back is stored on your computer, not in our database and not in a cloud sync.
Files. If your agent reads a document, analyses a spreadsheet, or writes a file, that work happens on your machine. The files don't move to our servers.
Team memory. What your agents have learned about your preferences, patterns, and priorities is stored locally. On most machines even memory search runs on your computer, with a local model the app downloads once.
Configuration and workspace data. Your agents' configuration, skills and personalisation, and the emails fetched, calendar entries cached and research compiled for you, all stay on your computer.
What leaves your computer
The prompt for each AI call. Your team reasons with large language models in the cloud. Each prompt goes through Maxiful's model proxy to the model provider: your message, the relevant conversation history, the task instructions, and excerpts of your local data when the task needs them. The proxy handles authentication and usage management and does not store the content of the call. By default we use only providers that don't train on customer data, unless the workspace owner allows providers that may train, which Maxiful holds off once a Google account has been connected; they keep a call only briefly, for operations and abuse monitoring. If you choose a model that runs on your own computer for an agent, its prompts stay on your machine.
Web searches. When your agent decides a question needs the web, the query goes to Perplexity through OpenRouter.
App actions in the apps you connect. Apps you connect under More work apps are reached through our connections provider in the United States, which holds their sign-ins for Maxiful and keeps what each app action sent and returned for up to a year.
What we hold on our infrastructure
- Account and billing. Your name, email address and plan tier. Stripe holds your card, and we don't see the full number.
- Usage metadata. The model name, serving provider, token counts, cost, time, plan tier and technical fingerprints of each AI call, buffered up to 7 days so your usage dashboard works. Never the content.
- Service metadata. Deployment status, agent health checks, error logs. No conversation content.
- Diagnostics. Whether setup finished, which model answered, which screen you were on, which marketplace item you installed. Never message, prompt, or file content, and you can turn them off.
What happens at setup
Setup happens in the Maxiful app on your computer: you name your Chief of Staff, describe your business, and connect the tools you use. What you tell it stays on your computer. When setup finishes, your email address goes once to our welcome-email service, which sends you a getting-started email.
Support access
We can't reach your computer. If support needs to see your agent's configuration or logs, we ask first, and only for a time-limited session. Your computer isn't streaming logs to us.
If our servers are unreachable
Your team and your data live on your computer. While our servers are unreachable, account features and cloud AI reasoning pause; your files, memory, and configuration are untouched, and the team resumes when service returns.

The transparency page lists every item, and the privacy policy covers the same ground in legal language, including how long we keep each item. If you have questions, email [email protected].
Your team runs on your computer. Your workspace stays local. AI reasoning is routed through Maxiful's model proxy to cloud model providers, by default under no-training terms. Now you know exactly what goes where.
