Google to Restrict Certain Apps from Accessing
Other Apps' Data
Not many people know about it, but smartphone
apps can easily access the data from other
installed apps. This way, some of the suspicious
apps can easily read your bank-related
information from different apps. Moreover, these
apps can also access your passwords stored in
another app.

Now, Google has announced that they will change
their Play Store policy from May 2021. According
to a report, Google will ask all app developers
which data they want to use from other apps
installed on the smartphone. Moreover, they will
also have to declare the specific reasons for
accessing that data. Currently, the apps on
Android 11 which request permission for
"Query_All_Packages" can easily view all
application data from a user's phone. Looking
into that concern, Google has decided to revise
the Developer Programme Policy. This revision
will restrict the app developers from accessing
sensitive data. Google said that the apps
requiring data access from other apps could
request for scope-appropriate visibility.
Banking-related applications have certain
expectations so that they can obtain some broad
visibility for security-related issues. If an
app developer asks for a "Query_All_Packages"
permission, he/she will have to declare this on
Google Play Console. After that, Google will
decide the license only if the developer's
application meets the policy requirement.

The applications that will fail to meet the
policy requirement will not access other app's
data. Moreover, if a developer does not fill the
declaration form on Google Play, he will not get
the required access. Also, Google will remove
these types of apps from Play Store. Google also
declared that the deceptive or non-declared use
of this permission could lead to the app's
suspension. Moreover, it can also result in the
complete termination of the developer's
account. Google said that the developers who
need their apps to use other application's data
would have to use app-discovery API. In that way,
they will not require to pull the entire list of
apps. Android 11 has introduced the
"Query_All_Packages" permission. Therefore, it is
applied to the apps that want to target the
Android 11 API level, called "API Level
30". These new restrictions will also apply to
all apps that want to target API Level 30 or
above. Therefore, it will not affect a lot of
applications as of now. It is a piece of good
news for Android users who keeps raising concerns
about data security.
