Where are your photos and documents? With Nextcloud you pick a server of your choice, at home, in a data center or at a provider. And that is where your files will be. Nextcloud runs on that server, protecting your data and giving you access from your desktop or mobile devices. Through Nextcloud you also access, sync and share your existing data on that FTP drive at school, a Dropbox or a NAS you have at home.
Nextcloud is free, open source and you can get involved in making it better!How to get started
Right now, nearly ALL data there is about you is stored at half a dozen companies, with names changing per country (Facebook, wechat, Vk, Google, Weibo, Tencent, Microsoft). They know where you live, what you search for, who you talk to, what you buy, what you eat and --probably-- what you think.
Your data represents who you are and can easily be abused.
And power gets abused. Always. Maybe by a local politician who doesn't like that you discovered his fraud. A local police woman who likes your boyfriend. A well connected businessman who likes to buy your store for cheap. A crime syndicate annoyed you try to help drug addicts kick off.
Even if your data isn't abused --they promise not to, right?-- isn't it nobody's business what you do?
We believe privacy is a right, a foundation for democracy. And we like to help you get it back.
And running your own, private Nextcloud server is the best way to get started!
Nextcloud is an open source community of developers and contributors, some helping out in their free time, others paid by their company to make Nextcloud better.

The easy web interface allows you to share files with other users on your server, to create and send password protected public links, to let others upload files to your cloud and to get notifications on your phone and desktop when a user on another cloud server shares files directly with you.

An efficient, easy to use interface is one of the main things that sets Nextcloud apart from the competition. Design is about more than being pretty. The goal is to allow users to get work done with the least amount of effort, making it obvious how to accomplish tasks and reducing the number of steps needed to do so.
Good design can be seen in the entire user interface and each release makes steps forward.
