Any good tool to make folder act as /dev/null?

Actually, I am concerned that Cryptomator writes logs in multiple files with different names in ~/.var/...cryptomator.../logs

I see that this is not super sensitive, but I wanna not have (even encrypted!) logs of my encryption software.

So few questions to you:

• How rational this approach? Or I am just overparanoid?
• Actually, any good approach to not store anything (even file headers) in folder?

For now I made rm -rf /logs and ln -s /dev/null /logs but it seems to misbehave. Someone say that i can mount that folder to RAM via fstab, but I think it is a “nuke against fly” method
