How to remove this?

[Nathan Malcolm]

Are you trying to remove the copyright details or the debug information? If you do the former you will be denied support as per our support eligibility policy.

[Docs: Help-Support_eligibility]

[.m.]

the debug information is visible to administrators only and it can be helpful in debugging when required.

if you still want to remove it then navigate to below location
admin panel >> configuration >> settings >> Server and Optimization Options -->
Advanced Stats / Debug information <-- select no and save settings
