Users counting and GDPR
<p>Do I need a GDPR "coockie" banner if I implement not a unique identifier but only a naive counter?</p>

<p>My web app check a key presence in local storage. Key is the same for all. If it's not found - call <code>/increment</code> api (with no message or data at all) and create one. If it already exists - do nothing. Just like "warrant canary". I like to call it reverse personification.</p>

<p>The GDPR covers information that can be used to identify a person. But a mere counter does not offer this possibility. </p>

<p>Do not link database entries to this cookie. For the GDPR, it does not matter whether personal data is stored directly in the cookie, or is merely indexed by this cookie.</p>
