Where can I download the KuCoin app?

Excuse me, I'm trying to access the KuCoin app but I'm having trouble finding it. Could you please guide me on where I can download it? Is it available on both Android and iOS platforms? I'm quite new to the cryptocurrency world and I've heard that KuCoin is a popular exchange, so I'm eager to get started. Additionally, is there anything specific I should keep in mind while downloading the app to ensure my security and privacy are protected? Thank you for your assistance.
