What it may read
Apple Health, Calendar, Reminders, Location, Microphone, and Speech are each granted separately, and only the categories you enable are ever read.
Private by default
A private AI assistant that asks before it shares
Most assistants decide for you what to send. Logos shows you the personal context attached to a request, names who will receive it, and waits. You can decline, allow it once, allow that context type in future, or turn cloud AI off entirely.
Controls
Four things you decide, not the assistant
What leaves the device
Before the first send, Logos identifies the information in the request and its recipients. Permission you grant can be revoked later without deleting your account.
Whether cloud AI runs at all
Cloud AI can be switched off in Privacy settings. New requests then stop leaving the device, and supported local features keep working.
What is kept
Export local data, delete local analysis and wellness history, reset local state, or request account deletion, all from within the app.
Connected accounts
Connected apps stay on a short leash
You can attach Gmail, Google Calendar, Google Drive, Slack, or Notion to a task. Authorization is handled through Composio, and OAuth tokens stay with Composio rather than Logos. Google Drive access is read-only, and Logos asks for confirmation before sending, creating, or changing anything in a connected service. Logos invokes only a fixed set of tools, and only for tasks where you explicitly attached that account. Disconnecting asks Composio to revoke the credential; where a provider does not support programmatic revocation, Logos tells you where to finish the job.
Commitments
What Logos does not do with your data
Logos does not sell your personal information and does not use it for advertising. Connected-app data is not used to train or improve generalized AI models, and use of Google API data follows the Google API Services User Data Policy, including its Limited Use requirements. Operational logs kept for security and troubleshooting exclude connected content, tool arguments, OAuth tokens, and raw connected-account identifiers. Service providers process information only to run the service and are contractually required to protect it. The privacy policy is the authoritative version of all of this.
Getting started
Start free, grant nothing you do not want to
The workspace preview is free: browse agents, try guest messages, and see how permissioned context works before subscribing. Sign in with Apple or with an email address. Logos is available in the United States, and is not a medical device. If health data is what you mainly want help with, see how Apple Health summaries work, or read the frequently asked questions.
