## Exposed data

- Date of birth
- Connection data (IP, logs)
- Email address
- Identity document
- Employment data
- Postal address
- Full name
- Phone number
- Order history

## What you can do

- Expect phishing attempts quoting your name and this company. A message that knows your details is not legitimate for that reason.
- These documents enable identity theft, and cannot be reissued at will. Keep the notification letter: it proves where the leak came from if an account is opened in your name.
- You can ask the organisation exactly what was exposed about you (right of access), and complain to the DPA if no answer comes within a month.
