All data uploaded to your account and stored privately or in draft requires no licensing, as only you can access it.
By making your data publicly available, you retain ownership of your research objects (as is often not the case with traditional publishing). All objects are licensed under CC-BY license, except for datasets, for which the CC0 licence is more appropriate. The detais of these licenses can be seen below:
This license lets others distribute, remix, tweak, and build upon your work, even commercially, as long as they credit you for the original creation. This is the most accommodating of licenses offered. Recommended for maximum dissemination and use of licensed materials.
CC0 can be particularly important for the sharing of data and databases, since it otherwise may be unclear whether highly factual data and databases are restricted by copyright or other rights. Databases may contain facts that, in and of themselves, are not protected by copyright law.
CC0 is recommended for data and databases and is used by hundreds of organizations. It is especially recommended for scientific data and thus encouraged by Pensoft (see their guidelines for biodiversity data papers) and Nature (see this opinion piece). Although CC0 doesn’t legally require users of the data to cite the source, it does not take away the moral responsibility to give attribution, as is common in scientific research. You cannot be held liable for any (mis)use of the data either.
