Welcome to Android Central! Which phone? Was this a preinstalled app or an app you installed from the Play Store?
It's up to you to back up or sync important data. Don't just leave it on the phone, because you can never predict when a glitch might happen, or the phone might get lost or damaged, or something similar.
