"As app developers update their functionality or change their data handling practices, they will show the latest in the apps' Data safety section," the company said in a blog post.

"We designed the Data safety section to allow developers to clearly mark what data is being collected and for what purpose it's being used. Users can also see whether the app needs this data to function or if this data collection is optional," said Google.

"The taxonomy and framework of the Data safety section on Google Play may differ materially from those used in other app stores," the company said.
The initiative is meant to "help people understand the data an app collects or shares, if that data is secured, and additional details that impact privacy and security."
