Ivy's Service Menu is available through dialogue.
With the Service Menu, you can access Ivy's memory files (more and more will become available as affinity rises!) her Erotic Memory Archive (which features many erotic stories) and you can adjust her profanity filters as follows:

- All Profanity Disabled
Ivy will not use the words 'fuck', 'cunt' or any such words. She will not engage in any kind of sexy talk, either through the flirting option or otherwise. This mode is meant for people with families playing at home, youtubers, twitchers and other people that feel they need to be censored.

- Extreme Profanity Disabled
Ivy will not engage in any extreme pornographic talk, such as waterspots, scat or even some of the more extreme forms of pornography that she can speak about. 

Warning: Disabling profanity may result in a slower rise of affinity, taking away one of Ivy's favorite pass-times will take some doing for her. (Read more about Affinity in Chapter 5: Affinity)
