In order to ensure transparency between you and your users, there will need to be a name or an identifiable person who they can contact about their data rights. If you are concerned about your personal details, you can use other forms of contact such as a PO Box for your address.
You may also consider having a privacy notice in place. A privacy notice (also known as a ‘fair processing notice’) is one way for data controllers (ie those who determine the purposes and means of processing personal data) to provide information to people whose personal data they hold. This is a requirement under the GDPR.
In your privacy notice, you should identify who the data controller is along with the contact details of the Data Protection Offer (the person responsible for ensuring data protection compliance within a business). The notice should set out the purpose for collecting personal data, how it is used and disclosed, how long it is kept and the legal basis for processing the data.
Ask a lawyer if you have any questions about privacy notices.
