Liar 

A statement made to dishonestly mislead another person.

The term is too broad. There needs to be three separate words.
One word where the liar has the intention to advantage themselves to the detriment of others. “I will clean my room today.”
One word where the liar has the intention to advantage the recipient of the lie without any detriment to the liar. “You did a very good job.”
One word where the liar has no intention to advantage or disadvantage anyone. “There is a Santa Claus.”
