With Synctrain you can securely synchronize files with other devices that have Syncthing installed. You can choose to synchronize full folders, or choose specific files. With Synctrain you can also stream audio and video files from other devices. When you synchronize files, all changes, including deleting files, also happen on your other devices. Do not use Synctrain for back-up purposes, and always keep a back-up of your data. You decide with which devices you share which files. This also means the app makers cannot help you access or recover any lost files. This app is powered by Syncthing. This app is however not associated with or endorsed by Syncthing nor its developers. Please do not expect support from the Syncthing developers. Instead, contact the maker of this app if you have questions.
