If for any reason you're not satisfied with the Fog of World app (Android version), we'll refund your money, no questions asked. Please note this offer is only available for Android users because Apple doesn't allow developers to refund directly.
You may request a refund by contacting Apple. But Apple will decide the eligibility.
Simply e-mail your order number (usually starts with “GPA”) to fogofworld@ollix.com during your first 30 days. The order number is a must as developers cannot get any user information based on Google's privacy policy. Also note that the whole refund process will be handled by Google Play.
PS. It's likely both Google and Apple won't let you purchase the same app again if you requested a refund earlier.
