How do I transfer my apps after selling them to another person?

First, congratulations!

You have two options:

1. The person who bought your apps will have to sign up for a separate account with us and integrate their SDK key (from that new account) into the apps you sold. The apps and revenue will start to show up in their account when they have pushed the apps with their SDK key included to the Google Play or App Store.
2. Additionally, you can transfer your entire account with AppLovin to that other person. They must update the payment information to their own information. Additionally, they will get all revenues from all apps/impressions for that account.
