Is GDPR really needed if my android app doesn&#39;t collect any personal data?
<p>I have developed some Android applications, and they don't store any personal data, but they do some calculation about some input, for example the annual salary provided by user and return to him a result to screen without saving any information.
Should this application need any GDPR popup or page?</p>

<p><strong>No.</strong></p>

<p>Given that the app does not transmit any data out of the user's device that can be used to identify the user, GDPR is not relevant whatsoever.</p>
