I mainly use gmail to communicate and I also make use of cloudservices like Google docs and Dropbox. This can mean that I store contact details and non-sensitive professional information but I try to minimise the amount of personal data that is stored and shared. Moreover, I try to make sure this is deleted as soon as this info is redundant but I’m not always the person in control.
Therefore, the content of your messages and your contact details sent via the contact option above can be used by Google and their third parties under US law.
I don’t collect any sensitive personal data, I don’t send out automated messages. I also don’t send emails to more than a few people without using the BCC option. I don’t use any analytics service to track traffic on my website except for the standard services provided by WordPress. However, I do save contact details in my Twitter/ Linkedin/ /Google/ Whatsapp address book to be able to get in touch with you. I will store this data for a long time.
