Yes, you can delete the Gboard app from your Android or iOS device. However, if you do so, you will not be able to use the Gboard keyboard to type on your device anymore. You will have to switch to a different keyboard app to type. Additionally, if you have any personal data or settings saved in Gboard, they will be lost when you delete the app. It's important to weigh the pros and cons before deleting the app and ensure that you have an alternative keyboard app or method of typing available before doing so.
