I do have a counters in beta version so I can give some numbers. If you are in area where there is reasonable amount of places, one call to FourSquare is 32 KB. I tested that in center of New York, it's 40 KB. One call the get nearest street crossings (OSM) is 4 KB.
BlindSquare knows the area it has got from 4sq and OSM so it makes new query when you are on boundary of last query. If you make category search or search by name, FourSquare result is 10-40 KB. If we estimate that BS makes 20 queries to 4sq in 60 minutes and 30 to OSM, it would mean 40*20 + 4*30 = 920 KB / hour. It's about 8 mb/h (mega bits/hour). I hope my math is okay. I can also test this in practice. If you drive by car you get more often to the boundaries and BS needs new data. PS. I'm currently implementing caching. It minimizes data usage when you are on same area and it gives also possibility to off-line use (for example preloading area from hotel wifi if you are abroad).
