GDPR, CCPA and more
The GDPR (General Data Protection Regulation) makes organizations liable for any violations of user privacy and deviations from a high data security standard.
Legislation like the CCPA (California Consumer Privacy Act of 2018) brings similar regulation to other countries.
Nextcloud has extensive GDPR compliance capabilities.
ePrivacy Regulation
The upcoming EU ePrivacy Regulation is designed as a complement to the GDPR. The objective is to reinforce trust and security in the Digital Single Market by ensuring that electronic communications from Europeans are confidential regardless of the technology used. The ePrivacy Regulation protects the confidentiality of electronic communications and information on devices, independently whether it is personal or non-personal data.
Nextcloud is designed to protect the confidentiality of communications and fully prepares customers for the upcoming ePrivacy Regulation.
Why metadata and self hosting matter
Metadata, often described as everything except the content of your communications, has less legal protections but can be incredibly revealing. From a list of who somebody talks to and when, much can be inferred!
The Electronic Frontier Foundation explains it well on their site.
Of course, service providers might promise not to store and track such meta data, but governments can simply force them if need be. For example, in the UK providers have been forced to record the website visits of their customers.
And that is not even mentioning the fact that even privacy-focused companies can suddenly be sold to a foreign entity. Like with the content of communication, the best way to protect metadata is to ensure it never leaks from your infrastructure in the first place.

Scalability
Easy for private use
Nextcloud Talk is designed for easy installation and operation. Nextcloud hosts a STUN server to facilitate usage behind firewalls and we recommend the installation of a local TURN server to improve connectivity further. Note that calls get fully routed through a TURN server, causing a lot of network traffic.
The peer-to-peer nature of Talk does inflate network traffic, creating one incoming and sending stream per other participant. This places practical limitations on calls that depend on network capabilities. A typical private Nextcloud Talk setup should handle dozens of calls with each up to 6-10 participants, up to 20 if all participants have a good network connection and do not use video. Enterprise limits, however, are in the thousands of participants per call.
Scaling in enterprise setup
To help with scaling, Nextcloud lowers video quality automatically and disables video on large calls. Sending audio and video, as well as the compute power required to decode the video streams on clients, are the biggest limiting factors, with most asymetric internet connections bottlenecked on upstream bandwidth and laptops and mobile devices especially having trouble decoding multiple video streams.
The High Performance Back-end offered by Nextcloud solves the bandwidth bottleneck and allows scaling a single call to much larger numbers of participants, up to hundreds or even thousands.
Scaling further: webinars, school classes
High Performance Back-end
Webinars and other large scale broadcasting type calls are possible with hundreds or thousands of participants. The High Performance Back-end setup includes special features for this.
The HPB also lowers the load from calls on the Nextcloud server, taking care of ‘signaling’ and optionally enables connecting a SIP bridge so users can dial in by phone into calls. The HPB runs on-premises, like Nextcloud itself, or through a hosted offering by our partners. Customers should be aware that it has significant dedicated bandwidth and processing needs. The HPB is available through Nextcloud GmbH.
Sign up for a free 30 day test of the hosted HPB offering in the Talk settings page.
