Short answer
Calenco is developed by NeoDoc, a French software publisher, and is built around a sovereign approach to technical documentation. Data can be hosted in France within a GDPR-compliant framework.
Security covers access control, traceability, user permissions, audit logs, and data reversibility. For organizations that require maximum control, Calenco can also be deployed on-premise.
This approach fits sectors where documentation is sensitive: industry, energy, healthcare, defense, quality, or regulated environments. Sovereignty is not a decorative claim, but an architectural choice.
