# Charging Fee

The DataSync service that GreenNode currently provides is completely **free for all users**, with no limit on the volume of data transferred.

However, because all GreenNode users share this service:

* The DataSync infrastructure is shared among all users.
* Performance may vary depending on the time and the number of users using the service at that moment.
* GreenNode strives to ensure the best possible performance for all users.

**Advanced usage needs:**

* If you need DataSync with higher performance, GreenNode can provide an advanced solution with guaranteed performance and configuration customized to your needs. For details, contact GreenNode.
