How long are chat logs stored?

Either general chat text or whispers, how long are they stored? I am asking here because I have been looking at various privacy statements and I couldn’t find an answer, so I am hoping a blue can clarify this for me.
Not interested in an exact number of days, just a general idea in terms of months or even years.

We have some information in our Privacy Policy

So it says about the length: “We usually retain data for only as long as necessary to provide you with products, services and an immersive entertainment experience.

So it depends on the type of data in many cases, it can’t be generalised. There is some contact information in the Policy if you have further questions though.
