windows phone 7 應用提交時遇到的位置服務問題

Allow me to draw your attention to this Windows Phone application Certification Requirement:

Requirement 2.7.2 The privacy policy of your application must inform users about how location data from the Location Service API is used and disclosed and the controls that users have over the use and sharing of location data. This can be hosted within or directly linked from the application.

Should you submit an application that uses Location Service API and do not provide a privacy policy you will get a friendly response from the certification something like this:

Fail: It appears the application uses location services but does not include a privacy policy describing how the application uses the Location Service API and what control users have over the usage and sharing of information obtained through that usage.

簡要的說就是應用程式需要提供關閉或開啟位置服務的設定（注意：這個設定只是針對應用程式本身，不是設定手機中的定位服務），提供設定的同時需要有隱私權聲明，向使用者說明你擷取位置的目的，承諾不會向第三方透露位置資料，我的隱私權聲明是：

隱私權聲明：此應用程式將使用您的當前位置，僅用於擷取您所在位置附近的商家和好友，增強使用者體驗，除此之外，我們決不會向任何第三方透露您的位置資料，請放心使用。您也可以禁用定位服務。如果您有任何疑問，請聯絡douliu@douliu.com。
