<h3>Description</h3>
<p>This application was developed to be used without a facebook account. Therefore it does not use the facebook API. Instead it opens the facebook event URI and downloads the website source code. This source contains the information which is used to create a calendar entry.</p>
<h3>Open Source</h3>
<p>The source code for this application is available at <a href=" https://github.com/akaessens/NoFbEventScraper">GitHub</a>.<strong><br /></strong></p>
<p>If you encounter an issue, please report it to me anonymously at the <a href="https://gitreports.com/issue/akaessens/NoFbEventScraper">Bugtracker</a> or directly at <a href="https://github.com/akaessens/NoFbEventScraper/issues">GitHub</a>.</p>
<h3>Donations</h3>
<p>I develop this application in my free time. If you like it, you can donate at <a href="https://www.paypal.me/andreaskaessens">PayPal</a>.</p>

<h1>Help</h1>
<h3>What links can be used with this app?</h3>
<p>All facebook subdomains are supported, whether mobile (m.facebook.com) or language-specific (de-de.facebook.com). The link must contain an event ID.</p>
<h3>How to use this application?</h3>
<ul>
<li><strong>Paste button</strong>: paste a copied link from the clipboard into the URL bar.</li>
<li><strong>Share to</strong>: Android's built-in share-function, e.g. from a browser.</li>
<li><strong>Open with</strong>: Android's built-in open-with-function, e.g. when clicking on a link in a messenger.</li>
</ul>
<h3>Why does event X not work?</h3>
<p>This app relies on event information that is publicy available. If the event does not offer for example the location without a login, it will not be available in this application. Events with multiple instances are problematic because they do not provide the correct start and end date when scraping from m.facebook.com.</p>
<p>If you encounter issues with a specific event, please let me know via the <a href="https://gitreports.com/issue/akaessens/NoFbEventScraper">anonymous bugtracker</a> or at the <a href="https://github.com/akaessens/NoFbEventScraper/issues/">GitHub issue page</a>.</p>
<h3>Is this compatible with my calendar app?</h3>
<p>Yes. This application makes use of application independent calendar functions, which makes it compatible to every calendar app. However, i recommend <a href="https://play.google.com/store/apps/details?id=ws.xsoh.etar&amp;hl=de">Etar Calendar</a> because it is Open Source.</p>
