just in case
As a precaution
Just in case is a phrase expressing precaution against an unlikely but possible event: I brought an umbrella just in case, Keep some cash on hand, just in case.
The phrase often stands alone when the potential problem is understood from context: I'm not expecting rain, but I'll take a jacket just in case.
