The app does not access or record any personal data including texts, emails, phone calls, passwords, and voicemails. Depending on your company's cellphone policy, hours of operation may be set so that LifeSaver does not prevent you from using your personal phone while driving outside of working hours.
When not driving, your phone will function normally without any interruption. When LifeSaver detects that you are driving however, if you unlock and use your phone, you will see a banner notification prompting you to lock your phone or to return to the LifeSaver app. If your company's policy allows, you may see a Passenger Unlock button and/or an Emergency Unlock button on the LifeSaver app home screen when driving. Using either of these buttons will record a violation and may affect your driver score. When driving, if you do not lock your phone when prompted by the banner notification, or get back to the LifeSaver app home screen, you will incur a violation that affects your driver score.
If you use a navigation app like Waze, Apple Maps, or Google Maps on your phone you can still use these while using the LifeSaver app without receiving a violation. Before you begin your drive you will want to open the LifeSaver app and tap the map icon. You will then choose which navigation app to use by tapping on that option. The app will launch and you can enter your destination. You will want to stay on the navigation app to prevent a violation.
