# Security and privacy

> How dfine.io - Review keeps your work and your data safe.

dfine.io - Review is built so you can share confidential work without worrying about who sees it. Here is how your work and your data are protected.

## Where your data lives

Your files and data are region-pinned to the EU and served from the edge, inside the European Union. This keeps your work within European data protection rules.

## Control who gets in

<Columns cols={2}>
  <Card title="Folder passwords" icon="folder-lock">
    Put a password on a folder so only people with the password can open it.
  </Card>

  <Card title="Protected share links" icon="lock">
    Add a password to any share link, so a stray link alone is not enough to get in.
  </Card>

  <Card title="Permission controls" icon="sliders-horizontal">
    Decide what each recipient is allowed to do with a shared link.
  </Card>

  <Card title="Expiring links" icon="timer">
    Set links to expire after 24 hours, 7 days, a custom date, or never.
  </Card>
</Columns>

## Protect your account

Turn on two factor login and set a session timeout under **Settings**, **Security**, so an unattended session does not stay open. You can change these any time.

## Keep a record

Every important action is written to the activity log, so you can see who did what and when, and download an audit copy when you need one. See [Activity log and compliance](/en/review/activity-log).
