Let’s read what Acer states about the Acer User Experience (AUE) Improvement Program does:
The Acer User Experience app is used to collect customer behaviors when using Acer PC products and send the information back for further analysis. This aids in improving the user experience and satisfaction of new products or updated versions of existing products.
What Acer does not tell is which data exactly is collected and transmitted, which would be essential for any data collection.
We recommend to disable this immediately if it was pre-installed by Acer on your computer.
