As the owner of your website, you are responsible for the personal data collected through it as you are the data controller (the business or organisation that is collecting and using the personal data). This means that it is your responsibility to ensure the data is stored securely and used correctly. 
You are also responsible for how any third-party components – such as widgets or iframes - use the data collected through your website – these are the data processors (businesses or organisations that process data on your behalf). Please note that all third-party components available through the it’seeze website editor have already been checked for GDPR compliance.
