The collected data is hosted on secure dedicated servers located in metropolitan France.

Data flows between the sub-meter network and the servers, as well as between the servers and the management software, are encrypted.

The servers on which data is stored are subject to real-time backups to other servers located in different cities in France.

Sub-meters are designed to store data locally if remote reading is impossible due to a technical issue.

Procedures are in place to identify and prevent any malicious intrusions into the information systems.
