In order to use the various services offered by Google on Android devices, you must sign in with your Google Account to start using your device. Once you’ve signed in, your device’s information will be registered on google’s server, and from now on, the information associated with your account, such as email and contacts, will be synchronized and stored on your device.
When you hand over your Android device to someone else, you can “remove it from your Google Account device” to remove your personal information. Then, the data such as the email and the contact attached to the Google account is erased, and it becomes unavailable.
In this case, it is data accumulated in the terminal that is deleted, it is a connection between the terminal and Google’s server. We’re not deleting your Google Account itself (you can, but won’t cover it here), so if you sign in to another device with that account, you’ll be able to use the same email, contacts, and other data again.
On the other hand, “log out” refers to eliminating the link between your Google account and your device. Data such as emails and contacts accumulated on your device remains intact, so you can use it again when you log in. The process of logging out can also be performed remotely by logging in to your Google account in your computer’s web browser and opening the screen in the order of “Security” → “Your device”.
In addition, when you initialize the Android device, in addition to the deletion of data / files, such as installed apps and photos, also deleted from the google account device associated with the device. There is no longer a worry about personal information leakage, but android devices with device protection features enabled will require you to log in with your Google Account, which you used before, and log out of your pc’s web browser.
