What is Personal Data? Our Digital Footprint in 10 Key Categories

We constantly share data when using the internet, shopping, or filling out job application forms. But exactly what information falls under the category of "personal data"? Let's examine this concept, which is fundamental to laws and digital security, under 10 main headings to get to know our presence in the digital world more closely.

Definition of Personal Data

In its simplest terms, personal data is any information that directly or indirectly identifies an individual. This includes not only your name, but also any technical and social information that helps you stand out from the crowd.

1. Identity Information: Our Core Asset

These are the most basic pieces of information that define us in the eyes of official authorities and society: full name, date and place of birth, parents' names, gender, and marital status.

2. Personal Information: Our Professional Background

These are the data that determine our presence and legal status in the business world. Curriculum Vitae (CV), professional experience, social security records, disciplinary actions, and criminal record information.

3. Communication Data: Accessibility

These are the gateways that allow others to reach us. These include our phone number, residential address, email address, and the registered electronic mail (KEP) address used for official correspondence.

4. Financial Data: Economic Portrait

This is sensitive information that reflects our economic strength and financial habits. It includes salary and income information, spending and tax data, bank account statements, credit card information, and credit scores.

5. Transaction Security: Digital Fingerprint

These are the technical traces we leave behind when we connect to the internet or a network. These include IP address, device IMEI number, MAC address, SSID, and Bluetooth ID information.

6. Physical Space Security: Observable Area

These are data recorded in the physical environments we inhabit. Examples include security camera footage, workplace entry and exit (turnstile) records, and vehicle license plates.

7. Marketing Information: Preferences and Habits

These are data that show how we behave in the consumer world . Shopping history, survey responses, cookie records, and campaign preferences.

8. Visual and Auditory Records: Biometric Reflections

These are media data that directly record our presence. Photographs, security camera audio and video recordings, interview or event recordings.

9. Communication Records: Communication Traffic

This shows the intensity and methods of our communication tool usage. It includes corporate phone call details, email correspondence content, and internet access logs.

10. Location Data: Position and Movement

These are coordinate data that determine our location over time. GPS data, HGS/OGS toll booth information, and location information from meal card expenditures.

Conclusion: Why Should We Know?

These 10 categories define the boundaries of our privacy in the modern world. Knowing which category our data falls into allows us to better defend our rights (such as those under GDPR) and decide what and how much we share on digital platforms.

Remember: Data you can't control isn't yours.
