As an AI language model, I don't have access to the current policies of Apple regarding the commission they take from the App store purchases. However, here's some information on the previous commission rates:

Until December 2020, Apple charged a 30% commission on all app purchases and in-app transactions made through the App Store. For example, if a user purchased an app for $1, Apple would take 30 cents as a commission, and the developer would receive 70 cents. Similarly, if a user made an in-app purchase of $10, Apple would take $3 as a commission, and the developer would receive $7.

However, in December 2020, Apple announced a new App Store Small Business Program, which reduced the commission rate for small businesses earning less than $1 million per year from 30% to 15%. This program went into effect on January 1, 2021.

It's important to note that the commission rates vary depending on the type of purchase. For example, Apple takes a 30% commission on app purchases, in-app purchases, and subscriptions during the first year. After the first year, the commission rate drops to 15% for subscriptions.

In conclusion, Apple takes a commission from App Store purchases, which was previously 30%, but reduced to 15% for small businesses earning less than $1 million per year. However, the commission rates vary depending on the type of purchase.
