Opened google.com, "DATABASE QUOTA EXCEEDED" before allow to proceed

Further to the "DATABASE QUOTA EXCEEDED" it then said below: "Do you want to allow the database "google.com" in undefined to use up to 500MB of storage space on your device?
ALLOW. Or DO NOT ALLOW

So I hit "allow" each time and nothing bad seems to happen, it just loads the questions I asked.
But this has happened on many more than 1 occasion in the last week or so and i'm not sure what implications this will have in future; on invoice or internal memory ie; wipe device at any 'un'given notice etc...
