Boitinhyeu, sorry to say, but Currently AxCrypt mobile app does not have an inactivity sign-out feature. Although you get this feature on desktop version. The Inactivity Sign Out feature is part of the Premium plan. You can use our Inactivity Sign Out feature, to sign out the AxCrypt app on certain time interval of inactivity. Also you can sign out the AxCrypt app, when opened the encrypted file(s). Now AxCrypt will ask the user to enter the sign in password to sign in to the AxCrypt app. You will be notified once it is released in Mobile Apps too.
For Inactivity Sign Out on desktop apps, go to File | Options | Inactivity Sign Out | Choose duration in minutes.
