Will deleting the app reveal privacy? Can I read personal information after the app is uninstalled?

First of all, deleting an app will not reveal privacy. It's hard to say whether you will reveal your privacy, because every app will make people agree to some agreements before you start using it. If you don't agree, you can't continue using it. If the app says in the agreement that it will read personal information, but the user chooses to agree, then the user's personal information will be read by the app. Even if it is deleted, personal information has been exposed.

Secondly, when the app is uninstalled, there is no way to read personal information, which has completely disappeared from the mobile phone, because after uninstalling the software, the software will automatically stop the previous operation. When downloading the software again, the option of whether to allow the software to obtain permissions will appear again.

All in all, after uninstalling the app, it is really impossible to read personal information, but if these apps get the address book, they will upload it directly to their own servers. Even if you uninstall it, you can't delete it. You must download the regular software.
