The European privacy law in brief

The GDPR (General Data Protection Regulation) is a European regulation that has been in force since 25 May 2018. Its core message is straightforward: if you collect or process personal data, you must do so responsibly - transparently, securely, and with a valid reason.

What counts as personal data?

Personal data is any information that can directly or indirectly identify a person. That is broader than most business owners realise:

  • Directly identifiable - name, address, phone number, email address, national ID number
  • Indirectly identifiable - IP address, purchase history, location data, cookie data
  • Sensitive data - health records, criminal records, biometric data, religious beliefs

If you have a customer list, send a newsletter, manage personnel files, or run a website with a contact form, you are processing personal data.

What does the GDPR require?

The law rests on several core principles:

Transparency

Tell people which data you collect, why, and what you do with it. You do this through a privacy policy.

Purpose limitation

Collect data only for a specific, legitimate purpose. Do not use it for anything other than what you collected it for.

Data minimisation

Do not collect more data than you need. If you only need an email address for your newsletter, do not ask for a date of birth as well.

Accuracy

Keep personal data up to date and correct inaccurate records.

Storage limitation

Do not keep data longer than necessary. When a customer relationship ends and you have no legal retention obligation, delete the data.

Security

Take appropriate measures to protect personal data against unauthorised access, loss, or theft.

Why does it matter?

Fines

Supervisory authorities can impose fines for non-compliance. For serious infringements, up to 20 million euros or 4% of annual turnover. In practice, SMEs receive lower fines, but they do occur.

Customer trust

Consumers are increasingly aware of their privacy rights. A business that handles personal data carefully earns trust. A data breach or privacy violation can destroy that trust instantly.

Competitive advantage

GDPR compliance is increasingly a requirement in B2B relationships. Larger companies ask their suppliers to demonstrate that they are compliant.

It is the law

Ultimately, the GDPR is not optional. It is an obligation for every organisation that processes personal data.
