GDPR - Personal data
<p>I've read the definition of "personal data" and I still can't understand it clearly. For example I have a youtube account and create a comment, is this comment now considered my personal data? If that is true, then wouldn't any data that links to user in database considered his personal data?</p>

<p>Thank You!</p>

<p>This is the definition:</p>

<blockquote>
  <p>‘personal data’ means any information relating to an identified or identifiable natural person (‘data subject’); an identifiable natural person is one who can be identified, directly or indirectly, in particular by reference to an identifier such as a name, an identification number, location data, an online identifier or to one or more factors specific to the physical, physiological, genetic, mental, economic, cultural or social identity of that natural person;</p>
</blockquote>

<p>You seem to mostly understand the definition.</p>

<blockquote>
  <p>I have a youtube account and create a comment, is this comment now considered my personal data? </p>
</blockquote>

<p>It is personal data about you. It isn’t necessary “your” data though; it is controlled by YouTube. Being personal data gives the data subject certain rights and creates obligations on the controller of the data but it doesn’t change who controls the data.</p>

<blockquote>
  <p>If that is true, then wouldn't any data that links to user in database considered his personal data?</p>
</blockquote>

<p>If the user is a data subject; yes. For example, data about corporations or governments or your cat or the majestic African wildebeest is not personal data unless it can be linked to a data subject - like if it can be worked out that the cat is your cat.</p>
