I just purchased Nine application from Google Play. How can I get a license key?

• If you purchase Nine from Google play, Nine complies with the Google play payment policy.
• If you download Nine with the purchased Google account, you can use Nine on multiple devices without additional purchase.

Thus, the license key is not provided.

• If your Nine would not change to the authorized license right after purchasing via in-app billing, please reboot your device and then check your Nine again.
