Mega is a cloud storage and collaboration service that started in New Zealand in 2013. It offers file storage and sharing with end-to-end encryption: files are encrypted on the user's device and Mega says it cannot decrypt them. Mega is available through a web client, apps for Windows, macOS, Linux, iOS, Android and Huawei, browser extensions and the command-line tool MEGAcmd.
Mega Limited is based in Auckland, New Zealand, outside the EU. According to its privacy policy, files are stored on servers Mega owns and controls, in Europe or in countries the European Commission considers adequate, such as New Zealand, and not in the United States. The source code of the client apps is published under a custom licence, which is source-available rather than open source, and the server code is not published. For European organisations, storage may therefore be in Europe while the provider is subject to New Zealand law.
