Clients cleansing cycle

Hi Guys,

I’ve got a question regarding data cleansing of the clients table. (This is what you see by clicking Permissions -> List all clients)
It seems this data is not stored infinite. Can someone tell me how the cleansing rotarion interval is? e.g. daily or monthly and how long the client id’s are kept.
Also, is there a way to enlarge this value?

Cheers!
