With in-app purchase, your end users can easily buy additional digital content from you without having to leave your application.
You can either:
unlock the additional content from within your application – for example, unlock additional game levels, or switch from free demo access to paid access
deliver additional content from a back-end server that you manage – for example, download a city travel guide from your server
You can sell the following content types:
Content – for example:
Premium levels for games
Virtual goods, such as additional tools or currency for a game
Downloadable components, such as city guides for a location-based application
Services – for example:
One-time subscriptions for various periods, such as a one-month, three-month, or one-year subscription to a mobile newspaper
Donations
You are not allowed to sell the following content types:
Tickets to real-world events
Physical goods, such as pizza
Physical merchandise in online auctions
Purchases that Nokia's Quality Assurance (QA) team cannot verify at the time of submission, such as loyalty points or prepayments for future releases
Content that does not adhere to the Nokia Store Content Guidelines
You use the current Nokia Store payment methods. The disbursement and revenue sharing are the same as for Nokia Store content, with you receiving 70% of Net Revenue. This applies to payments received through both user credit card as well as operator billing. (Before July 2011, revenue sharing from operator billing was only 60%.)
Revenue excludes taxes and other losses. For details about Nokia’s payment policy, see the Terms and Conditions, which outline the distribution agreement for Nokia Store content.
Nokia Store handles the payment processing. You simply provide us with the purchasable contents' descriptions and price points.
If you want to protect your purchasable content from unauthorised distribution, you can use either:
built-in Digital Rights Management (DRM) – When you submit your content to Nokia Publish, it is encrypted before being published to Nokia Store. When consumers complete an in-app purchase, Nokia Store silently sends a key to the on-device license key manager. This unlocks the purchased content for the device. For details about how DRM works and how to add it to your application, see section Digital rights management.
your own access control – You handle the content delivery, log any necessary usage data on your back end server, and prevent any unauthorized use of the purchased content. When consumers complete an in-app purchase, you can deliver the protected content or the keys for unlocking protected content, from the back end server.
In some cases, for example, when end users buy new devices, they lose ownership or access to content they purchased through in-app purchase. For these situations, your application must provide a way for end users to restore their ownership or access.
How the content is restored depends on the content type:
built–in content – Nokia Store handles the restoration.
content delivered from a back-end server – You handle the restoration.
