Change effective on October 2, 2019.
Recently, you may have noticed that Datally no longer reports the amount of data used by apps on your phone, and no longer blocks data usage of specific apps. Due to the way Android interacts with Datally, some of Datally's data features are going away on Android 5 (Lollipop) and Android 10.
How can I keep using Datally?
Datally is fully supported on Android versions 6 through 9 (Android Marshmallow, Nougat, Oreo, and Pie). In addition, starting in Android 7 (Nougat), data saving features are part of the Android operating system and can be found in your phone’s settings.
