Very last yr, Google attempted to rein in this conduct by avoiding applications from accessing this data by default commencing Android 11, even though also introducing new authorization identified as “Query_ALL_Deals” for apps that have to have access to the checklist of other put in applications.

“This filtering habits helps minimize the total of possibly delicate facts that your application does not need in purchase to fulfill its use scenarios, but that your application can however access,” Google stated.

Google also claimed it would not enable applications to ask for the Query_ALL_Offers permission when the “info is obtained for the function of sale” or the expected task can be realized by an choice system.

“Applications that fail to fulfill plan specifications or do not post a Declaration Form may well be eliminated from Google Participate in,” the firm observed. “If you adjust how your application works by using these restricted permissions, you ought to revise your declaration with updated and accurate data. Misleading and non-declared works by using of these permissions may perhaps result in a suspension of your app and/or termination of your developer account.”
