On 30 April 2026, Delta Dore — a French manufacturer of connected smart-home and home-automation systems, based in Brittany — disclosed a data leak affecting users registered on its professional training portal, formation-pro.deltadore.fr. The incident exposed the personal data of at least 374 people.

The exposure was tied to the company's online training platform for professionals (installers and partners) rather than its consumer products. According to the breach tracker reporting the incident, Delta Dore moved to notify the individuals concerned.

Reported exposed data categories include:

  • Personal identity details of registered users (training-portal accounts)
  • Account/registration information held by the training site

The full scope and root cause were not detailed in available reporting, and at least 374 people were identified as affected. The company's response and the outcome of any regulatory notification remain unconfirmed.
