Purpose limitation means you collect a client’s data for a specific, stated reason and you only use it for that reason. This protects privacy by preventing data from being used for unrelated purposes without clear justification. In practice, if a client shares their contact details to book a facial appointment, those details should not be used for marketing or other activities unless you have explicit permission or the use is clearly compatible with the original purpose. If you ever want to use data for a new purpose, you assess whether it’s compatible with the original purpose or you obtain new consent, or you anonymize the data.

Data minimization focuses on collecting only what you truly need, consent is about obtaining explicit permission to process data, and transparency is about clearly informing clients about how their data will be used. The principle described here directly addresses restricting data use to the original purpose to protect privacy.
