Cloud storage since the very beginning is not secure and is going to get your data spied on by hackers and as we learned even the companies who provided the service to you who told you they'd respect your privacy.

I'd recommend NAS storage. And since we are MIUIers it is amazing to have the world's biggest best AIoT platform at our fingertips just for this purpose. I own a Mi Router HD which has a whopping 1TB storage space. With it you can access your files from anywhere and the best part is that only YOU get to decide who has access. Xiaomi's products have been tested by hackers and they've already stated that Xiaomi takes care to keep you safe. Then thanks to Mi Home you can allow people access, deny people access. You are in control of your own cloud!
