A data controller refers to an individual or organization that determines the purposes and means of processing personal data. In the context of a cleaning service, the data controller may be the company providing the cleaning services.

The collected personal data in this context may include information such as the customer's name, address, contact details, and preferences. The purpose of collecting this data is to effectively provide and manage the cleaning service. It helps the cleaning company to schedule appointments, assign cleaners, and ensure that the service meets the customer's specific requirements.

By collecting personal data, the cleaning service can also maintain a record of past services provided, track customer feedback, and improve their overall service quality. It is essential for the data controller to handle this personal data responsibly and in compliance with applicable data protection laws to ensure the privacy and security of the customer's information.
