Own data getting tracked

My own data shows up in the reports and statistics etc and also when I add something to card just for the sake of checking if everything works.

I know that it is normal but is there an app or something else I can do to completely exclude or remove my data because my values change and get manipulated. Thanks for any help!

You can create your own report, you can filter it however you like, you can put session city is not (your city), you can put customer is not (you), you can do whatever you want. The world is your oyster!
