# Privacy and visibility controls

CTD gives you full control over what's visible and to whom. This article covers the settings specific to individual users — for a deeper look at data collection and storage, see [Controlling your network visibility](/content/guide/article/security-visibility/index.html) in the Security & Privacy section.

## What CTD collects — and what it doesn't

CTD only looks at email **metadata** — who you've exchanged messages with and how recently. It never reads, stores, or surfaces email content. Subject lines, message bodies, attachments — none of that is touched.

## What's shared with your team

If you join a team workspace, your teammates can see _that_ you know someone — enough to surface a warm path — but not the history behind it. They can't see your email activity, message frequency, or any detail about your relationship beyond the connection itself.

## Your visibility settings

You control who can see your network. Go to [Settings → Privacy](https://app.ctd.ai/account/privacy) to:

- **Set your network mode** — Closed (default) means only you see your contacts. Open shares your network with people you know on CTD.
- **Mark contacts as private** — any individual contact can be hidden from everyone, regardless of your network mode.
- **Whitelist or block** — open your network to specific people or company domains, or block competitors from seeing anything.

## Removing your data

You can disconnect any account (email, LinkedIn) at any time from [Settings → Accounts](https://app.ctd.ai/accounts). To request full data deletion, contact [support@ctd.ai](mailto:support@ctd.ai).
