When you open it
What it will ask for, and why
Location
Choose “Allow all the time”
So it can send you alerts and learn your trips. GPS is only used while you're driving and switches off after 6 minutes without moving. Your trips are saved on your phone.
Notifications
So it can tell you in time
For your leaving alerts, the one the night before and the directions on the way.
Battery
So your phone doesn't close Fluye
Choose “Don't optimise” for Fluye. On some phones, especially Samsung, Xiaomi, Huawei and Oppo, this stops the system from closing the app.
