How to Opt-Out interest-based ads on ROKU Devices?
Opting out of interest-based advertising is totally optional and does not mean you will no longer see advertising on the Roku app. It means that we may not show you ads that have been tailored to your interests. We may block interest-based ads whenever possible but sometimes device settings or browser settings may prevent us to set opt- out configuration.
Below are instructions for using the advertising choice mechanisms for your Roku Device.
Go to the menu of your device, find the “Settings” and press OK.

Go to Privacy >> Advertising.

Check ON option “Limit ad tracking”
That’s all. You can go back to Home to enjoy your content.
