Cortex is a place to keep your thinking, so it is fair to ask what happens to it. Here is the honest picture.

​
Where your data lives

Your brains, pages and files are stored on managed cloud infrastructure. Content is encrypted at rest, and the databases behind Cortex are not exposed to the public internet: they sit on a private network that only the application can reach. In short, your knowledge is held securely, not sitting in the open.

​
The member list is the boundary

Access to a brain is its member list, full stop:
  • Only members can open a brain, search it, or reach it through an agent. A brain you have not been added to is invisible to you; you cannot even confirm it exists.
  • Your work brain starts with one member: you. Nothing anyone else does adds them to it; you would have to add them yourself. Anything that lands there, an agent conversation, a quick upload, an incoming meeting, is visible only to you unless you deliberately promote it elsewhere.
  • Roles cap what members can do. Readers read; Writers write; Admins and Owners manage. Your agents act as you and are held to the same roles, checked live on every request.
One honest note for team accounts: workspace brains belong to the workspace, the way files in a company drive belong to the company. Workspace admins do not see your brain in daily use, but they administer all of the workspace’s brains when running it demands it, for example exporting or reassigning a brain when a member leaves.

​
Connections and access

When you connect an agent, it acts as you within the workspace you approved, and no more. Its access follows yours, live: brains you gain, it gains; brains you lose, it loses instantly. You can see every connection on the Connect page and revoke any of them instantly. Nothing is connected that you did not approve, and nothing stays connected that you revoke. More on connections.

​
Deleting

You can delete pages, and their version history goes with them. You can delete brains you own. Deleting your account removes your data. If you need help with a specific deletion, get in touch.
