Your Own API Key: Offer, No Toll

The app doesn't require a key to communicate. Your own key is for people who use AI for hours on end and want to take some of the load off the shared connection.

Path: AI chapter, select your own key, choose a provider. Do not post the key in chats, do not take screenshots of it, and do not link it to children’s accounts that you do not monitor.

Any costs will be charged to you, not through the token shop in the app. If you don’t use it much, leave the field blank.

I treat this as an option, not a requirement. The door to the exercise remains open even without it.
