As stated in last year’s blog post, we fought against hundreds of thousands of impersonators, apps with improper articles, and Potentially Harmful Applications (PHAs). In a continued fight against these kinds of programs, not only do we employ advanced machine learning models to identify questionable programs, we also run dynamic and static analyses, intelligently utilize user engagement and feedback data, and leverage proficient human reviews, which have helped in finding more awful programs with greater accuracy and efficacy.

Back in October 2018, we announced a new policy restricting the use of the SMS and Phone Log permissions into a restricted number of instances, such as where an program has been selected as the user’s default app for making calls or sending text messages. We have recently started to remove apps from Google Play that violate this policy. We plan to present additional policies for user data and apparatus permissions throughout 2019.

Despite our improved and layers of protection against apps, we know bad actors will continue to try to evade our systems by cloaking behaviors and altering their tactics. We will continue to enhance our capabilities work to provide our users with a safe and safe app shop, and to counter such adversarial behaviour.

In addition to preventing and identifying bad programs from entering the Play Store, our Google Play Shield system now scans more than 50 billion apps on consumers’ devices each day to be certain programs installed on the apparatus aren’t behaving in harmful ways. With this kind of protection, programs from Google Play are likely to damage an individual’s device than Android apps from other sources.

We find that over 80 percent of policy violations are conducted abusive programmer networks and by repeat offenders. When malicious programmers are banned, they create new accounts or purchase developer accounts to be able to come back to Google Play. We have further enhanced our clustering and account fitting technologies, and by combining these technologies with the expertise of our human reviewers, we’ve made it harder for spammy developer networks to gain installs by blocking their apps from being printed in the first place.

In 2018, from entering the Google Play Store than ever before, we introduced a series of policies to protect users from new misuse trends, detected and removed malicious programmers quicker, and ceased more programs. The amount of app submissions increased by over 55 percent, and we increased program suspensions . These increases can be attributed to our continued efforts to tighten policies to decrease the number of harmful apps on the Play Store, as well as our investments in automated protections and human inspection processes that play critical roles in identifying and enforcing on bad apps.

Google Play is committed to providing a safe and protected platform for countless Android users on their travel discovering and experiencing the apps they revel in and love. To deliver against this commitment, we considerably increased our group of product managers, engineers, policy specialists, and surgeries leaders to fight against bad actors, and worked last year to boost our abuse detection systems and technologies.


Users’ privacy and data is a vital factor in building user trust. We required developers to what’s necessary to provide the features of an app, to limit their device permission requests. Also, to help users know how their data is used, we’ve required developers to provide disclosures about the collection and use of user data. We rejected or removed tens of thousands of programs that weren’t in compliance with the policies of Play associated with privacy and user data.
