Developers can disable or restrict clipboard access within their app. This is typically done by customizing text fields so that they do not support copying text to the clipboard. An alternative approach is to implement a custom clipboard management system within the app, which controls how and when data can be copied, potentially encrypting it before it's placed on the clipboard.

Restricting clipboard functionality can lead to major user inconvenience, particularly in apps or data fields where users frequently need to transfer information, such as pasting passwords from password managers. Furthermore, limiting clipboard access might create barriers for users relying on various accessibility technologies.
