Hi @robbadobba,
WavesLocalServer is a background process that is used to facilitate cross plugin communications, preset scanning, advanced plugin features and licensing abilities.
This service does not collect or transmit any personal user information or usage data.
The reason this service stays open in the background is to optimize loading and scanning times. We are working to minimize the resources it requires.
There is no problem if the service is terminated, but it will be relaunched by the plugin once it is needed.
Thanks
