1. There are 3 types of subscription tiers for your choice (1-month/ 1-year/ lifetime). Your subscription tier will determine how long you can use the program to download movies and TV shows from Prime Video.

2. To ensure the service, your monthly or annual plan will be auto-renew after 1 month or 1 year. If you don't need it anymore, you can cancel the renewal subscription service before the renewal date.

If you have other questions about the subscription, please read KigoSoft Subscription FAQ.

Q:Since the program can only download videos from amazon.com from Amazon US, UK, DE, and JP, you can't use the program to download videos from primevideo.com.

Q: There are three options for video quality (High/Medium/Low) in the settings window, enabling you to download videos with different output quality according to your devices. To download HD videos, please make sure your computer supports playing HDCP-enabled content, otherwise, you can only download videos with low or medium quality.

Please click here and then tap on "Get HDCP Status" to check whether your device supports HDCP-enabled content or not. If you get "HDCP is available for ..", it means that your computer is able to get HD videos from Amazon Prime Video.

First of all, please make sure the video you want to download can be played normally on the web browser of Amazon Prime Video.
