Hi @ryukseo,
Greetings from the Roku Community!
We understand you want to know if the Roku device had an ACR. We're happy to assist you further. Please be advised that ACR is built into Roku TVs and identifies shows, movies, games, and ads being accessed on the TV. This data targets (or reverse targets) advertising campaigns to meet marketing objectives.
Hope you'll find this info useful. Let us know in case you still have any questions.
Kind regards,
John
