The App Security Improvement program is a service provided to Google Play app developers to improve the security of their apps. The program provides tips and recommendations for building more secure apps and identifies potential security enhancements when your apps are uploaded to Google Play. To date, the program has facilitated developers to fix over 1,000,000 apps on Google Play.
How it works
Before any app is accepted into Google Play, we scan it for safety and security, including potential security issues. We also continuously re-scan the over one million apps on Google Play for additional threats.
If your app is flagged for a potential security issue, we'll notify you immediately to help you quickly address the issue and help keep your users safe. We’ll deliver alerts to you using both email and the Google Play Console, with links to a support page with details about how to improve the app.
Typically, these notifications will include a timeline for delivering the improvement to users as quickly as possible. For some kinds of issues, we may require you to make security improvements in the app before you can publish any more updates to it.
You can confirm that you’ve fully addressed the issue by uploading the new version of your app to the Google Play Console. Be sure to increment the version number of the fixed app. After a few hours, check the Play Console for the security alert; if it’s no longer there, you’re all set.
The success of this program rests on our partnership with you—the developers
of apps on Google Play—and the security community. We’re all responsible for
providing safe, secure apps to our users. For feedback or questions, please
reach out to us through the Google
Play Developer Help Center. To report potential security issues in apps,
please reach out to us at
