Overview
Sync-in is a sovereign, open-source platform for file storage, sharing, synchronization, and collaboration. It is intended for individuals, businesses, public-sector entities, and institutions seeking a controlled, scalable solution suited to their operational requirements.
Deployed on the infrastructure of your choice, Sync-in is built on an architecture where files remain directly readable and usable. This choice ensures data reversibility and allows files to continue being used outside the platform.
Sovereignty takes concrete form here through control over infrastructure, data reversibility, and governance over how data circulates. From their original location to the spaces where they are used, files remain within a visible and controllable governance chain. Shares, anchors, and permissions remain revocable without owners losing control of their files.
Collaborative spaces allow teams to organize files, share content, and work together in a controlled environment. Fine-grained permissions allow rights to be adapted to users, groups, guests, and operational roles, while activity tracking and file locking help secure day-to-day work.
Sync-in integrates with existing work environments without fragmenting access governance. On desktop and mobile, users access their files with the same permissions. This consistency extends to synchronization on Windows, macOS, and Linux, command-line tools, and document integrations with Collabora Online, OnlyOffice, or Euro-Office.
