When you join the NGI Community, you might be sharing some data with a third-party that may not be FundingBox (owner of the NGI Community platform) and that have their own Terms and Privacy and Data Retention Policies. In those cases, the entity or individual managing the Open Call/Community is the controller of the data and FundingBox acts just as a processor.
In the Privacy section you will find the list of Open Calls and Communities you are part of and the tools needed to manage your data within.
