Using Personal data before consent
<p>I am having an Android App which is going to use some services such as Google Analytics, Firebase etc.</p>

<p>I have a thought of having two different consent screens for different region user such as EU Users will have a screen in which the checkbox will be unchecked by default whereas users from other region will have the checkbox prechecked. </p>

<p>I would be using the GPS location before taking the consent to find out the users region(Location may not be exact location).</p>

<p>Now my question I will use the GPS location to only check the location and WILL NOT STORE IT OR COLLECT IT AT ANY COST.</p>

<p>Does the GDPR or any other privacy law stop or disallow me to do that?</p>

<p>Any help will be really useful.</p>

<p>Doing this is OK according to the GDPR and other European laws.</p>

<p>The relevant bit is GDPRs rules for <a href="https://gdpr-info.eu/art-6-gdpr/" rel="nofollow noreferrer">Lawfulness of processing</a>, and in particular Article 6 (1)b, which says that it is legal to do this if</p>

<blockquote>
  <p>processing is necessary for the performance of a contract to which the data subject is party or in order to take steps at the request of the data subject prior to entering into a contract;</p>
</blockquote>

<p>In your particular case, signing up for using your app is "entering into a contract" and it is the data subject who has requested to use your app that is subject to this processing.  </p>
