Respect for licences

For transport open data:
The transport data used by the API comes from producers (transporters and other transport organisations) that have chosen to release their data as Open Data. It is understood that uses several sets of data subject to heterogeneous licences that must be strictly complied with.
It is understood that Kisio Digital does not mix said heterogeneous data to recreate a new unique data base. The data bases are processed individually and enhanced by the Kisio Digital teams to be redistributed in GTFS format on the website or via the API. The aggregation of data bases occurs only in the navitia engine, for which each element is subject to its own terms.
During their use of the website, the re-user undertakes to comply with the laws and regulations in force, the open data licence conditions for the sets of data, expressly referring to the licences in question in order to know the extent of the applicable rights and obligations.
The notices to be included regarding these licences are available on the following page:
In order to make any use of the API, users are obliged to include the notices stipulated in the licences for the sets of data used in the credits for their application.
It is recalled that Kisio Digital undertakes to study the licences for sets of data before making them available to re-users or to negotiate specific agreements with the producer in the event that the obligations are too restrictive or incompatible with the licences in order to guarantee the legal availability of the data, subject to the appropriate licence.
For address data:
To complete its service, collaborates closely with Open Street Map, an international project founded in 2004 with the aim of creating a free map of the world. The navitia software includes the address data and POI from Open Street Map in order to redistribute them to users.
The address data can be freely re-used under an ODbl licence that includes an attribution clause and a share-alike clause. If you use an OpenStreetMap map, you are bound to include a credit for "© OpenStreetMap contributors".

In the event of any failure to comply with these CGU, Kisio Digita reserves the right to suspend access for a User of the API and to take legal action in particular in the event of infringement.
