# Removing Synchronised Data

The rationale for this is that trainers can repeat a training process without the device having any historical data or risking showing any previous training data to other users (a possible GDPR issue depending on what data previous users have used when training).

To clean a device of its training data you can perform the following steps.

1. Login to the application

We recommend you restart the application and log back in to make sure that no data that has just been removed is still in the application memory.
