How do Pidgin resolve incoming messages?

[yhujeehlok]

Hello I use XMPP and have logs disabled.

I want to be sure incoming messages leave no trace on my hard drive. Are incoming messages temporary saved on my disk and can be recovered with forensic tools or are they stored in the RAM until the chat window is closed? How does this work.

I use OTR and sometimes OMEMO. The messages decrypt on my device and leave traces on my disk even with logs disabled?
