Data is encrypted and decrypted into the app by the use of a private and unique safety key for each user. It is protected during all exchanges even if the network is compromised.

Fluid experience

Condensation uses a distributed architecture. Queries are shared between several independent servers for efficient data transfer. This process ensures the fluidity of the network and minimal loading time for users.

Data is seamlessly synchronized into the application to optimize treatment. Only changes are transferred through the network to minimize the quantity of exchanged queries.
