Google recently informed developers that, as of March 31, 2011, they will be changing their pricing model on the Android Market to a "Buyer's Currency" Model. The email explained that the change will simply help coordinate purchases for multiple currencies internationally. Here are the details:
Now jokesters and conspiracy theorists can speculate on the future of a global Google dollar...Android Market is changing to a new model for pricing applications called “Buyer’s Currency.” The change directly affects how you price your apps, as well as how users around the world purchase them.
We're writing to let you know that we’ve recently added several new currencies to the program: AUD, HKD, JPY, NZD, and SGD. Please visit the Android Market Developer Console to set prices in these new currencies by March 31, 2011.
IMPORTANT On March 31, 2011, Android Market will automatically assign Buyer’s Currency prices for your products in the new currencies if you have not manually set them in the Developer Console. Android Market assigns a price based on the price of your app in your home currency, converted to each target currency using the exchange rate on that day. This is a one-time conversion associated with the transition to the new Buyer’s Currency model. If you have already set your per-currency prices manually, Android Market will not override them.
You can continue to set and adjust the prices of your apps at any time, in your home currency and in any Buyer’s Currency available.
For more information about how Buyer’s Currency works, please visit the Android Market Help Center:
