Will Using Paddle Logger Affect My Data Plan?
The short answer is no.
Paddle Logger operates by recording GNSS signals on your phone, having the added benefit that you don't need phone signal for Paddle Logger to track your journey.
You will need an internet signal to record the correct location at the end of your trip. However if you have no signal at the end of a journey you can manually edit some trip details.
A connection is also required when projecting the journey onto a map.
