MyTrails lets you freely define the locations you download offline, so you don’t have to select a particular map number or administrative division when you purchase a map. Also, when you no longer need to have a given map offline, you can remove it and download another map without any additional cost (like a map lending library), so you don’t have to pay for a very big subscription, only what you need to have access to simultaneously.

This flexibility does mean that we can’t offer perpetual licenses (similar to owning, but in the digital world actual ownership is getting scarce).
