Synkron
Synkron is an open-source file synchronization app for macOS that helps you keep folders matched, backed up, and compared across locations.
What is Synkron?
Synkron is a native desktop utility for synchronizing folders on macOS. It is designed for people who want to keep files consistent between two or more locations, such as working folders, backup copies, external drives, or shared project directories. The app focuses on file and folder sync tasks rather than cloud storage, giving users direct control over what gets copied and compared. Common workflows include mirroring documents between devices, reviewing file differences before syncing, scheduling recurring sync jobs, and restoring earlier changes after a synchronization. Synkron is open-source software created by Matúš Tomlein and is also available on other desktop platforms, which can be useful in mixed-device environments.

Safety overview
Status: Mostly safe
Synkron is a legitimate folder synchronization tool, and its file access is central to what it does. Because it can copy, replace, and mirror files between folders, the main practical risk is accidental overwriting or propagating unwanted changes if a sync job is configured incorrectly. Review the source and destination folders carefully before running large or automatic syncs, especially when using external drives or important work files.
Recommendation: Keep Synkron if you actively use it to maintain mirrored folders or backups. If you no longer rely on its sync jobs, you can remove it, but export or note any folder-pair settings you may want later because removing the app may also leave your saved sync configuration unused.
