Ceum is built for one person: everything you create belongs to your account, and there's no shared workspace, team, or multi-person space. The app reflects that — there's no user-management area and no roles. This article explains the model so the cross-references in other articles make sense.
What "your workspace" means
When Ceum articles say "your workspace", they mean everything in your account:
- Your items — clients, projects, tasks, invoices, transactions, subscriptions, time entries, documents.
- Your configuration — statuses, task types, relationship types, brand info, general settings.
- Your tag library, MCP tokens, exports, email logs, and templates.
There's no admin area and no team members. Signing in always brings you to the same set of data.
Data can still leave your account. You can hand one record out at a time as a read-only share link, which needs no Ceum account to open and can be revoked whenever you like. What does not exist is a second person inside your workspace.
What about external tools?
External tools can read and write your data through MCP tokens (see Integrations and MCP). A token acts on your behalf — it isn't a separate user. When a tool edits a task, the change shows up in the changelog as an external tool with the token's name, but it's still your data.
Signing in
You sign in to reach your account; the steps are covered in Signing in, and you manage your profile and sign-in security under Account settings.
Why this matters in practice
- Sharing is read-only and one item at a time. A share link covers a single invoice, task, kanban board, document, transaction, calendar, or generated file, and the recipient can only look. For anything wider — a copy of your whole client list, say — generate an export and hand over the file.
- There's no "transfer ownership". To move your data to a different account, export it and import it there.
- History is scoped to you. The per-item changelog and the MCP events log only ever show your own actions.
- Deletion is final. Deleting your account through Account settings permanently removes everything you own.
Tips and edge cases
- No admin pages. If an older article references an admin area, treat it as outdated.
- No shared ownership. Two people can't jointly own or edit a client or a project. A share link gives someone a read-only view; it never gives them a seat in your workspace. The "client" in Ceum is a customer of your business, not another Ceum user.
- Tokens are personal. Don't share MCP tokens between people. Each person should run their own Ceum account and create their own tokens.
