ACIAH-Linux is a free Linux operating system designed for older people and people with disabilities. The installation is voice-guided, the system is simplified, and it can be operated with a single finger through the Aciah-Menu and a dedicated heart key. It is distributed as an ISO image that you download and install on your own computer; the developers also offer remote assistance and tutorial sites with guides.
ACIAH-Linux is developed by the French association A.C.I.A.H (Accessibilité, Accompagnement Humain et Lien Social), whose registered seat is in Châteaubriant. The team consists of salaried staff and volunteers, and the association is a member of the Fédération des Aveugles et Amblyopes de France. According to the Comptoir du Libre catalogue, the software is licensed under the GNU GPLv3. Because it is an operating system that you install yourself, your files and data stay on your own device. No hosted service is mentioned; the project website is hosted by OVH.
