le-bon: There is optional information you can provide, but NeoReader collects your device ID, time, and what you scanned. Depending on how your set it up at install, it may also collect location.
It then aggregates all of your scans for analysis. NeoReader always reroutes your scans to their server first. This has been a complaint of NeoReader for a long time and why some techies won't use it. Consumers have no idea.
