A data controller is a key legal role in data protection. If you handle personal data for clients, you likely act as one.
What is Data controller?
A data controller is the person or organization that decides why and how personal data is processed. As a freelancer, you become a controller when you collect and use client or customer information, like names or email addresses, to deliver your services.
Why is this important?
This role comes with legal responsibilities under regulations like the GDPR. If you mishandle data, you could face fines or damage your reputation. Understanding your role helps you comply with the law and build trust with clients who care about privacy.
How does it work?
You determine the purpose of processing data, such as for invoicing or project communication. You must then ensure the data is collected lawfully, kept secure, and not used for other purposes. You are responsible even if you use a third-party tool, like an email service, to process it.
Pros and cons
The main advantage is control; you decide how data supports your business. Key disadvantages include legal liability and the administrative burden. You must document your processes, implement security, and sometimes appoint a representative if working internationally.
Conclusion
Recognizing yourself as a data controller is essential for modern freelancing. It's not just a technicality but a core part of professional, compliant service delivery. Taking simple steps to understand and manage data protects both you and your clients.
