Minimal Function Shopping List

This app is just one step above a note tagged to a shared fridge. Create easy to use and easy to share shopping lists.
Not much to describe:

-add items.
-remove items.
-have a digital shopping list in the most minimal way.
-share a digital shopping list in the most minimal way.

Good to know:

-all data is encrypted, only you and whoever you share your list with can decrypt its content.

Important to know:

-a list will be deleted if there is no interaction for a year. We figure you won't need that list anyway.

-if you you lose access to a list and do not remember the passcode, no one except other users of that list can assist you in regaining access.
