# App Risk Warning

Some Android phone systems, especially Huawei's HarmonyOS, have strict rules around crypto. Simply detecting the word "crypto" may cause the system to flag the app as malicious.\
\
However, if you downloaded the APK from the official website <https://dexx.ai>, it’s completely safe.\
On some Huawei devices, you may need to disable Pure Mode or disconnect from the internet to install.\
\
*\*For your safety, never click on or install APK files sent to you by others.*
