Google is tightening the screws on app developers by making it compulsory for them to comply with the User Data policy, specifically the part about privacy. Applications that don’t meet requirements will be severely checked when it comes to visibility in the store, if not removed from it outright.
Some developers use the data they gather from users in what might be termed as “unethical” ways. They sell it to third party advertisers in an attempt to make some quick cash. Before this, it wasn’t compulsory for them to disclose exactly how they are using the data they are gathering from users.
Some developers, in the past, have gone as far as storing the URLs of all the sites that the user visited while making use of the app, which is a massive breach of privacy. There also have been cases where hackers have gotten access to personal pictures and videos being stored by the application.
With this move, Google is attempting to keep users safe from privacy breaches, and indirectly from data theft. The User Data policy of the company also encourages developers to encrypt communication with the help of HTTPs.
If your application doesn’t comply with the guidelines soon, Google will delete it from the store. You can hire professional app developers to update (and upgrade) your app for you and avoid being wiped out from the store.
