If I buy it from taobao，I will get an register license code. Can I use it to register without mac or win?
Welcome to the forum, and thank you for your question. Your English is perfectly understandable.
If you only have an iPad, we recommend purchasing Aeon Timeline either through the Apple App Store or directly through our official website.
Please note that we do not sell Aeon Timeline through Taobao, so we are not affiliated with any listings there and cannot verify what product, license, or support you would receive if you purchase through that platform.
If you purchase through our official website, you will create an Aeon Timeline account and use that account to sign in to the app on your iPad.
If you have any questions about purchasing or setting up Aeon Timeline on your iPad, please let us know and we’ll be happy to help.
