Habib Wannous
I've been using Proton Drive for a while now and I'm really impressed. The interface is clean, it's easy to upload and access files, and most importantly, I trust it with my data because of the strong privacy and encryption features. It's a great alternative to big cloud services if yo u care about security and transparency. Highly recommended!

Unlike traditional forms of data storage (such as hard drives), cloud storage uses servers in off-site locations to store data, letting you access your files any time you want as long as you have a device that connects to the internet.
