Welcome to Android Central! Which phone exactly? There are a few that have the name "Max" in them.
On most Android devices, the clipboard is a system function, not a separate app. It is very transient, and only holds the last thing you copied. To see what's in there, go to any blank text field (like on a note-taking app), long-press and tap Paste.
There are 3rd party clipboard manager apps that give you more flexibility. Try Clipper or Clipboard Manager.
