I wanted to share with you my story, maybe it will help somebody to prevent removal of your app by Google, without any notice, from Google Play.
Google has decided to remove my app, Worldscope Webcams, from Google play store in the moment the application had 4.4 rating based on more than 11,000 user reviews and just a bit before the application reached one million downloads and after being available on Google play for four years.
The official reason was a violation of a developer distribution agreement - we have offered to our users a possibility to remove ads by buying a registration code via PayPal. Buying Ad-free version via Google play store was not possible, because our country is not on the list of supported locations for merchants which are allowed to sell paid applications on Google store.
What was most confusing to me is that a similar buying process (purchasing the registration code outside of Google play) uses one very popular app on Google Play. That app is marked as "editor's choice" and "top developer".
The Google's answer to my appeal was: "Thank you for your note.
We have reviewed your appeal and will not be reinstating your app. This decision is final and we will not be responding to any additional emails regarding this removal."
Nice, isn't it?
