There are three ways of certifying an app:
Via Android Developer ID: you can upload an app into Catappult using the same email address used to distribute it on the Google Play Store. This means that, when you upload an app, we check it on other app stores and if the email address matches, we can confirm that you are the legit owner.
Via Email: if you submit an app using one email address but you have access to the one registered on Google Play, a link will be sent to the second and it will be valid for a short time to certify the app.
Via Signature: you can prove that you can sign an apk with the same signature as the app you are trying to certify. To do so, you'll have to download a dummy APK provided by us on the back-office, sign it, and upload it again for us to compare. Check more here.
It may take up to five business days for your app's certification request to be reviewed by the Catappult team. In the meantime, you can change the app's information, such as title, description, and screenshots if you wish. You may also submit new apps and request their certification too.
About the app being marked as trusted, that is totally dependent on the security team and the tests they do in order to better promote the safest market store possible, so it varies as a result of many factors.
It depends on the certification method you chose. If you are using the Android Developer ID, you must make sure you have access to the email address that is public for your app in Google Play (support email). If you choose the Sign APK method, please make sure you use the same signature as in the app you are certifying.
It might also be that your app has been rejected because of not meeting content guidelines or quality standards. This might happen because we detected some performance or stability issues with your app or eventually some malicious code (malware, adware, phishing or similar).
