Thank you for replying, but I don't quite understand what you wrote in the context of a writing assistant where there is no sharing in any form with anyone.
Generative LLM's like this often reveal confidential info that they were trained on, and anything provided to them in order to generate other output can be used as future training data which can then be re-iterated to others
The latter can't be true since the input never leaves your computer, it's private information. The comments you're writing right now on the other hand are public information and can and will be used to train an LLM.
