# How to apply a license
Originally Nextcloud was licensed under the GNU AGPLv3 only. From
June, 16 2016 on we switched to "GNU AGPLv3 or any later version" for
better long-term maintainability and to make it more secure from a
legal point of view.
Additionally Nextcloud doesn't require a CLA (Contributor License
Agreement). The copyright belongs to all the individual
contributors.
