Location Reminders are an exciting new feature of the app, with a privacy-first approach. All location information is stored solely on device, and never shared with anyone else.
You can add a Location Reminder from the app's Settings or directly in Pointers Detail -- when you're next at that location you will receive a notification telling you which card to use to maximize your savings. It's that easy! Note that only 20 locations can be active at one time due to system limits.
