Clear the activity history on my (unpaid) account

I am the sole user of my zoho account so that keeping a history of everything I do online is not useful to me. I also would rather not have anyone else keeping track of what I do, either. I can see a use for this if I were a sysadmin managing multiple accounts but this is not the case.

I noticed that there is a Clear All Other Sessions button on the Settings/General/User Sessions page but found no such option for Activity History.

How can I clear the records displayed in Settings/General/Activity History? How can I opt out of this feature?
