| Incident dated | March 25, 2025 |
| Accounts affected | 16,627 |
| Sector | Digital services |

## Exposed data

- Email address
- Postal address
- Connection data (IP, logs)

## 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.
- 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.
