We use our personal data across countless platforms, such as websites, apps, social media, and almost everywhere online. But keeping our data protected is crucial and challenging at the same time. Every click, every location, and every device ID can reveal a person’s sensitive data and breach their privacy. That’s where the GDPR comes into play.
So, what is considered Personal data under GDPR? Personal data under GDPR is any information that relates to a living person who can be identified. That includes direct identifiers like names and emails, and indirect ones like IP addresses, device IDs, and online behaviour.
In this blog, you’ll see exactly what is considered personal data under GDPR, why it matters, and how to handle it wisely.
What is UK GDPR?
UK GDPR is the data protection law in use in the United Kingdom. It originally came from the EU GDPR but was modified to fit with UK laws after Brexit, and works in association with the Data Protection Act of 2018 (DPA). Together, they determine how organisations will collect, process, record, and store personal information while ensuring individuals maintain control over their data.
Following the UK GDPR and DPA was considered respectful and a trust-building exercise towards customers. It provides assurance to individuals who have had their data processed that they are being respected and that their trust is being maintained in the way their information has been processed.
Key Differences Between UK GDPR and EU GDPR
The basic principles remain the same. However, the UK has now established its own unique data protection and privacy system that is different from that of the EU. The UK GDPR is enforced by the Information Commissioner’s Office (ICO), in contrast to the EU, where multiple regulators exist. Different approval mechanisms apply for cross-border data transfer contingent on the transfer direction.
What Stays the Same in Both Regulations?
Both rules handle personal data in very similar ways. They follow the same key principles and give people the same rights over their information. In practice, most organisations follow nearly the same compliance processes under each system.
Which Regulation Applies to Your Organisation?
If your organisation operates in the UK or processes data of people living in the UK, UK GDPR applies. If you serve customers in EU countries or monitor behaviour there, EU GDPR applies too. Many businesses must follow both, especially if they operate or sell across borders.
What is Personal Data?
Personal data refers to any kind of information that relates to the identity of a living person directly or indirectly. It includes basic details like names and emails, as well as hidden information such as IP addresses, device IDs, and browsing behaviour. All data elements collectively contribute to identifying a person.
Direct Personal Data
Personal data is direct personal information that immediately identifies someone. This can be full names, emails, phone numbers and home addresses. These are the most conspicuous facts that can isolate an individual.
Indirect Personal Data
Indirect personal data doesn’t identify someone individually, but can when combined with other information. This includes IP addresses, device IDs, location information, browsing behaviour, and data from cookies or browser settings like preferences.
Sensitive Personal Data
Sensitive personal data includes details that require extra protection, such as health information, racial or ethnic origin, political opinions, religious beliefs, and biometric data. Handling these requires extra care under GDPR.
What is Considered Personal Data Under GDPR?
Any information that can identify a living person, either directly or indirectly, is considered personal data under GDPR. These are both obvious things, such as names, emails, phone numbers, and subtle information such as IP addresses, device IDs, location data, or online behaviour. Every work has its significance and duty.
Every piece of personal data matters. Managing it properly builds trust, stops misuse, and keeps people in control of their own information. Organisations must respect all data. Trust, privacy, compliance, and demonstration that customers value and have control over their information are achieved through proper management.
Types of Personal Data Covered by GDPR
GDPR secures extremely diverse personal data, which makes all identifiers managed in an accountable manner. What are the types of data in GDPR?
1. Direct identifiers: Name, email, phone number, home address.
2. Indirect identifiers: IP addresses, device identifiers, location information.
3. Online behaviour: Browsing behaviour, social media, buying behaviour.
Other types of identifiers include the membership numbers, the login IDs, and any information that can identify a person.
Special Category (Sensitive) Personal Data
Some of the personal data is more sensitive and requires additional protection under GDPR.
- Medical records, health information, or treatment.
- Racial or ethnic origin
- Political opinions
- Religious beliefs or philosophies.
- Biometric or genetic data
- Trade union membership
What is Not Considered Personal Data?
Certain types of information are not covered by GDPR because they cannot be used to identify a living individual:
Anonymous or aggregated data – information that cannot be linked to a specific person
Business contact details – such as work emails or company phone numbers
Information about deceased individuals – data relating to people who are no longer alive is not protected
Publicly available organisational information – details about companies or organisations that are accessible to the public
How Personal Data is Processed Under GDPR?
Any activity done with respect to a person’s information is personal data processing. According to GDPR, this activity has to be conducted in a responsible manner such that the data is kept safe and the individual is in control of his or her data. Organisations keep trust for compliance through the use and processing of information.
What is Processing?
Processing is the entire cycle for dealing with personal data, which includes collecting, storing, using, or sharing it, and deleting it altogether. Pseudonymising is the method of replacing identifying information with coded data in order to reduce privacy risk while still making it possible to analyse the data.
| Processing Step | Description / Actions |
| Collection & Storage | Gathering, recording, organising, structuring, and saving personal data |
| Usage | Retrieving, consulting, using, combining, analysing, and adapting data. This can include pseudonymisation to protect identities |
| Sharing | Disclosing, transmitting, disseminating, or making personal data available |
| Deletion | Erasing, destroying, or permanently removing personal data when it is no longer needed |
How Organisations Collect and Use Personal Data?
Organisations collect and use data for specific purposes, making sure it is relevant, necessary, and handled with care and transparency.
| Data Use Category | Description / Actions |
| Registration & Accounts | Collecting sign-ups and user information |
| Transactions | Recording purchase history and payment details |
| Online Behaviour | Tracking website visits, engagement, and interactions |
| Marketing | Sending communications and personalised offers |
| Service Improvements | Analysing data to enhance products and user experiences |
Lawful Bases for Processing
Data can only be processed if there is a lawful reason, ensuring fairness, accountability, and compliance with GDPR principles.

Special Data Categories
Some personal data is sensitive and requires extra protection to prevent misuse, harm, or privacy breaches.
| Lawful Basis | Description |
| Consent | Permission given by the individual |
| Contract | Processing needed to fulfil a contract |
| Legal Obligation | Processing required by law |
| Vital Interests | Protecting someone’s life |
| Public Task | Processing for official or public duties |
| Legitimate Interests | Balanced against the individual’s rights |
Individual Rights in Processing
GDPR gives people rights over how their personal data is handled, ensuring transparency, control, and protection.
| Individual Right | Description |
| Access | View personal data held |
| Correction | Update inaccurate personal data |
| Erasure | Delete data (right to be forgotten) |
| Restriction & Objection | Limit or refuse how personal data is processed |
| Portability | Move personal data to another provider |
GDPR Terminology You Should Know
Understanding GDPR terminology makes compliance simpler and more effective. Knowing the key roles, terms, and concepts ensures your organisation handles personal data responsibly.
Key Roles Defined in GDPR
GDPR defines specific roles with responsibilities for data protection:
| GDPR Role | Description |
| Data Subject | The individual whose personal data is being processed |
| Data Controller | The person or organisation deciding why and how data is processed |
| Data Processor | The entity handling personal data on behalf of the controller |
| Supervisory Authority | Regulatory body ensuring organisations comply with GDPR |
Common GDPR Terms Explained
These terms frequently appear in GDPR discussions and documents:
| GDPR Term | Description |
| Consent | Clear permission from the data subject to process their data |
| Data Breach | Any accidental or unlawful access, loss, or disclosure of personal data |
| Processing | Any action performed on personal data, including collection, storage, and sharing |

Essential Concepts for Compliance
Understanding these concepts helps organisations stay GDPR-compliant:
| GDPR Concept | Description |
| Accountability | Organisations must demonstrate compliance with GDPR principles |
| Data Minimisation | Only collect personal data necessary for the stated purpose |
| Purpose Limitation | Use personal data only for the specified reason |
| Privacy by Design | Incorporate privacy measures into systems and processes from the start |
Understanding GDPR Data Protection Principles
Through GDPR compliance, organisations legally protect themselves and show customers how much they value their privacy. It results in a lesser penalty, better workflow in the day-to-day operations, and strengthens responsible data handling.
What Are the 7 Key Principles of GDPR?
There are seven major principles that guide the overall administration of personal data under the control of a system. These principles make provisions for fairness, security, and accountability.
1. Lawfulness, Fairness and Transparency: Process data legally and clearly.
2. Purpose Limitation: Information for a specified, legitimate purpose.
3. Data Minimisation: Collect only what is required.
4. Accuracy: Data should be accurate and kept up to date.
5. Storage Limitation: Kept only as long as necessary.
6. Integrity and Confidentiality: Ensure that data is safe and secure.
7. Accountability: Organisations must demonstrate compliance with these principles.
How GDPR Principles Protect Personal Data?
The principles of the GDPR assist in risk reduction, the prevention of abuse, and the guarantee of proper treatment of data. They assist organisations to maintain security, improve their processes, avoid breaches, and sustain confidence with individuals whose data is processed.
Applying GDPR Principles in Your Organisation
Applying GDPR principles means applying privacy by design to everything: systems, policies, and workflows. This includes training staff, implementing secure storage, obtaining clear consent, regular audits, and monitoring that will make apparent all dealings with personal data, plus compliance and responsibility of the entire organisation.
GDPR Training for Staff
Applying GDPR principles can be overwhelming for organisations and business owners. In that case, a proper online training on GDPR can be effective. High Skills Training provides a GDPR Training Course that will not only help you learn a systematic and professional approach to maintain GDPR guidelines, but also provide a recognised certificate that will prove your expertise in the specific subject.
Why GDPR Principles Are Important?
Following GDPR principles puts an organisation on the right side of the law. It builds trust and enhances reputation. Lower fines are another benefit, along with better operational efficiency. Most important is an ethical commitment to the protection of personal information and respect for individual privacy.
How Long Can Personal Data Be Retained?
Personal data should only be retained by organisations or businesses as long as it is necessary. GDPR requires organisations to balance operational needs, individual privacy and minimise risks without breaching compliance.
Retention Periods Under GDPR
The retention under GDPR is determined by the type and purpose of data. Organisations should set timelines and handle information in a responsible manner.
- Customer account info: Kept while the account is active
- Financial records: Retained per legal and tax obligations
- Employee records: Maintained for HR, payroll, and legal purposes
- Marketing data: Stored until consent is withdrawn or the purpose is complete
The determinants of Data Retention
The duration of personal data retention depends on a number of factors:
Legal & Regulatory Compliance: Industry-specific laws and GDPR set minimum retention periods
Business Value & Operations: Information required for operations, audits or future projects
Data Sensitivity & Classification: Sensitive personal data (PII) requires stricter controls
Risk Management: Over-retention increases legal and cybersecurity risks; premature deletion may cause non-compliance
Litigation Holds: Preserve data for ongoing or anticipated lawsuits
Cost vs. Benefit: Balance storage expense against potential future utility
Deleting or Anonymising Data Safely
When data is no longer needed, it must be securely removed or altered to prevent identification and reduce compliance risks.
Safe Deletion (Irreversible)
- Digital Data: Use secure deletion software to overwrite files multiple times
- Paper Records: Shred using cross-cut shredders, not strip shredding
- Process: Ensure backups are also deleted and document the disposal
Anonymous Safety Precaution (Preventing Re-identification)
- Remove Direct Identifiers: Eliminate names, emails, SSNs, etc.
- Pseudonymisation: Replace identifiers with codes, keeping keys separately for re-identification
- Generalisation: Varying ranges or wider categories should be used instead of details
- Randomisation/Noise Addition: Slightly alter data to obscure individuals while keeping overall patterns
- Permutation: Shuffle attribute values within datasets to break links
- Differential Privacy: This involves introducing randomised noise to safeguard the individual and maintain aggregate information
Why is Personal Data So Important?
Personal data is not just data; it is a bundle of lives with real conditions dwelling on it. Any organisation dealing with it in this discovery will handle it with due diligence, therefore developing customer trust and, simultaneously, communicating to consumers that their privacy matters here. Proper viewing and handling of personal data will only enhance relationships and protection for people from misuse.
Data drives the decision and improvement of innovation. It is by pattern that organisations can improve their service, individualise experience, or plan for the future. However, if data is used carelessly, and it usually is, it can destroy reputations. This makes the ethical use of data imperative.
It is also part of its legal obligations under the GDPR. Being compliant reduces the risks of financial loss through breaches or fines while being able to demonstrate accountability and integrity. The organisation will respect personal data, valuing people rather than just data points.
GDPR Data Breach: Causes, Consequences, and Compliance
A GDPR data breach occurs when personal data is accessed, disclosed, lost, or destroyed without authorisation. Understanding the causes, consequences, and response steps helps organisations protect individuals and remain compliant.
Very few causes, except the attack, the error, or the weakness of the system. Finding the causes is itself finding prevention above that.
Attack Code: Phishing, Ransomware, Malware, SQL Injection, Credential Stuffing
Human Error: Misconfigured Cloud Storage, Data Sent to the Wrong People, Lost Unencrypted Devices, Poor Training of Staff
Insider Threats: Theft or Modification of Data by Authorised Users, either Deliberate or Accidental
Weak Points in Systems: Software that’s not updated, errors in apps, and poor access controls
Consequences of a GDPR Data Breach
The risks are legal, financial, operational, and reputational. Such risks are applicable to organisations as well as individuals.
Fines: Up to €20 million, or 4% of annual global turnover for the most serious infringements
Reputational Damage: Loss of business due to diminished confidence, negative publicity, and brand devaluation
Legal and Operational Impacts: Lawsuits and injunctions. audits. restricted processing. expensive remediation
Personal Harm: Identity fraud. Financial loss. Discrimination.
GDPR Compliance Application & Response Actions
Organisations must act quickly and methodically to minimise impact and meet legal obligations.
1. Contain & Investigate: Stop the unauthorised access, secure datasets and assess the risks to individuals’ rights.
2. Notify the Supervisory Authority: Report immediately to the concerned Data Protection Authority within 72 hours, or sooner, if high risk.
3. Notify the Individuals: Inform affected data subjects as soon as the breach occurs, giving them timely information to respond in case of high risk.
4. Document: Keep comprehensive records of factors, impact, and remedial action.
5. Re-establish Security: Reinforce technical (e.g. encryption, access control, and organisational mechanisms-training, policies).
6. Review and Improve: Conduct a post-breach analysis of the incident, including updates to processes and staff retraining against recurrence.
GDPR Tips: How to Protect Personal Data?
Collect only what is needed. The less you ask for, the easier it is to look after and the lower the risk. People like to know why you need their details and how it helps them get what they came for.
These tips help you keep that promise with clarity and confidence.
1. Collect Less, Care More
Take only the data you truly need, including cookies and cached data. Limiting unnecessary tracking reduces risk and builds trust.
2. Decide Who Gets In
Access should be intentional. Give people only what they need to do their job. Control creates safety and reduces mistakes.
3. Lock the Doors
Encrypt information. Secure your systems. Use tools that protect the data people rely on you to safeguard. Security only matters when it fails, so get ahead of it.
4. Train the Humans (They Matter Most)
Most breaches start with a simple click. Teach your team to spot threats and avoid traps through regular GDPR training. A trained team becomes your strongest defence.
5. Update Before It Breaks
Outdated software invites trouble. Patch it. Update it. Make it a habit, just like brushing your teeth.
6. Keep What Is Useful, Delete What Is Not
Data should not live forever. Remove what you no longer need. Clearing out old information keeps you safer and more compliant.
7. Share Wisely
If data must be shared, share it securely. Use passwords and encryption. Sharing data is not casual; it is a responsibility.
8. Audit Yourself Before Someone Else Does
Check for weak points. Fix what you can. Small, regular reviews prevent big, unexpected problems.
9. Have a Plan for “What If?”
Mistakes and breaches can still happen. The best teams prepare in advance. Know your steps so you can respond quickly and reduce the impact.
10. Be Honest With People
Tell people what you collect and why. No surprises. Transparency builds the trust every organisation needs to grow.
Frequently Asked Questions
Are Training Records Personal Data?
Yes, training records can be personal data if they contain information that identifies an individual, such as name, contact details, job role, or performance results. Under GDPR, these records must be handled securely, stored for a lawful purpose, and retained only as long as necessary.
What Are the 6 Legal Bases for Processing Personal Data?
The six legal bases under GDPR are consent, contract, legal obligation, vital interests, public task, and legitimate interests. Consent requires permission. A contract is needed to fulfil an agreement. Legal obligation is required by law. Vital interests protect life. Public task covers official duties. Legitimate interests respect individual rights.
What Are the Principles of the Personal Data Protection Act 2010?
The Personal Data Protection Act 2010 requires organisations to follow notice, choice and consent, disclosure, security, retention, access, and accountability. Individuals must be informed, give permission, have their data protected, be able to access and correct it, and organisations must handle personal data responsibly and securely.
Conclusion
Understanding what is considered personal data under GDPR helps organisations know what information they must protect. It is actually about telling the people that their personal information is handled with care and respect.
When organisations handle data safely, they avoid problems, build trust, and create a culture where privacy matters to everyone. This protects both the people whose data is used and the organisation itself.
By following GDPR rules regularly, organisations can make things safer and more open. Good data habits give people confidence, build loyalty, and help businesses work smoothly and responsibly.
