Clipboard Cleaner

Check and clean your clipboard using service, widget, shortcut and quick setting tile. - DeweyReed/ClipboardCleaner

As you may know, Android clipboard content and its changes can be got by any app, which is a security hole if you care about it(more info is mentioned here[https://github.com/grepx/android-clipboard-security]). Any app can get your copied password, credit card numbers and more.

However, ClipboardCleaner can't protect your passwords from being got by any app(after all it's a security hole). But it gives you ways to check and clean your clipboard.

Fortunately, Android has AutoFill or other mechanisms to handle sensitive info. Android Q also fixes this problem once and for all (https://developer.android.com/about/versions/10/privacy/changes#clipboard-data).
