What Does Restore Purchase Mean

What does it mean to resume a purchase? ۔

So some of my free apps say in settings: Restore purchase. what is the meaning of this ???? Why do we say this in our free app? Like a magic piano

For example: Angry RDS is a free game, but you can buy items in the game for free ... They ask you to return your purchase after purchasing points, coins, levels, etc.

When you purchase an app on another device and want to buy it on another device. As an example. I bought a powerful eagle update on angry rds on ipod and i want it on ipne, then click and i will get it
