Is it necessary to keep the syncthing running on my pc?

I just installed Syncthing on both my PC and my Android device. I want to know if I close my PC tab (running Syncthing address 127.0 …) and the syncthing app running as a seperate instance which looks like log files on cmd interface; would the files still sync? Also, I noticed a lot of sync time lag for even simple photo (size: 900KiB). Is there any solution to it? Please note, I am not running any proxy servers.

Hello @SyncO, welcome to Syncthing!

Yes, you can close the browser tab, but the Syncthing windows needs to continue running.

You can start Syncthing with the “no-console” parameter in Windows autostart to run it in the background. Alternatively you can install SyncTrayzor
