my page with the nickname pustotaL I do not know how to delete it
@PustotaL You can delete your TRN account here Tracker Network | Settings - Delete Account (thetrackernetwork.com) however we cannot delete account data in the form you are asking.
Apex Legends has an open API which basically means anyone can see the information all we do is allow things to be viewable in the fashion we do.
While some games such as Valorant/Halo/CoD support the ability to have completely private profiles removing them from any third-party sites, Apex Legends does not have this feature.
Apologies
