 Yet another F-Droid client.
 
 [![Release](https://img.shields.io/github/v/release/michatec/michas-droid)](https://github.com/michatec/michas-droid/releases/latest)
 
+## Warning ⚠️
+
+Google has announced that, starting in 2026/2027, all apps on certified Android devices will require the developer to submit personal identity details directly to Google.
+
+Since the developers of this app do not agree to this requirement, this app will no longer work on certified Android devices after that time.
+
 ## Description
 
 Unofficial F-Droid client in the style of the classic one.
