The GDPR states that I must have a lawful basis for processing your personal data. There are different lawful bases depending on the stage at which I am processing your data. If you have had therapy with me and it has now ended, I will use legitimate interest as my lawful basis for holding and using your personal information. If you are currently having therapy or if you are in contact with me to consider therapy, I will process your personal data where it is necessary for the performance of our contract. The GDPR also makes sure that I look after any sensitive personal information that you may disclose to me appropriately. This type of information is called ‘special category personal information’. The lawful basis for me processing any special categories of personal information is that it is for provision of health treatment (in this case therapy sessions) and necessary for a contract with a health professional (in this case, a contract between me and you).
