To delete your Google Hangouts chat, simply select the ‘Delete Chat’ button at the bottom of the chat window.
To delete Hangouts from Gmail, go to your Gmail settings and select “Hangouts” from the list. Next, click on the “Delete this chat” button. This will remove the app from your Gmail account and you will no longer be able to use it.
To delete the app from your iPhone, go to Settings > General > Storage and iCloud Usage. Scroll down to the list of apps and find Hangouts. Tap on it and then tap Delete App.
No, deleting your Google account does not delete your Hangouts messages. Hangouts messages are stored in the cloud and can be accessed by signing into your Google account.
The Google Hangouts app is not present on the laptop by default, so it needs to be downloaded. To do this, open up the Chrome browser and go to https://hangouts.google.com/. From there, download the app for your computer.
