Your Roku device allows you to add and remove the channels from the channel lineup. If you want to make sure that your child doesn't have access to channels you consider unsuitable, you can easily remove them. After that, setting up the purchase PIN will prevent them from downloading the app again. Here’s how you can remove any channel from your Roku device: 1. On your Roku remote, select the “Home” button. 2. Move to the right and select the channel you want to remove. 3. Press the "Star" button on the remote, which will open the "Options" menu. 4. Now, select “Remove channel” and make sure to confirm when prompted. Important: if you want to remove a subscription-based channel, you must first cancel the subscription. You can find "Manage Your Subscriptions" when you sign in to your Roku account.
