The Application must be installed from the Google Play Market Store only.

When using the Application the User must not:
😇
- turn off the previously granted permissions to the Application
- switch to the Split screen mode, including turn on broadcast mode from a mobile device
- use the camera in obvious or hidden mode (both front and back)
When the Application notifies that the camera is enabled, make sure that all background apps that have access to the camera are closed at the time of the transaction.
As well, make sure that the system functions allowing the device not to turn off the screen due to the constant background use of the front camera are turned off. The Application can also report the camera being on due to the activated Face ID feature.
- allow that the tapXphone application screens are not overlay by other apps/system functions.
Generally, this situation happens with messengers.
All applications/system functions that overlay the tapXphone screen must be turned off at the time of the transaction.
- try to take screenshots or videos of the screen.
- use mobile device remote control applications (for example, TeamViewer, AirDroid).
The User should update the OS and components that affect the security improvement in a timely manner.

It is also recommended:
- to download applications only from trusted vendors in the Play Store and applications that verified by Google Play Protect.
- to install malware detection tools on the device and keep it up to date.
