The Circle promotes absolute transparency as key to a better world, promising to eliminate crime and corruption through constant surveillance. However, this leads to the loss of privacy, suppression of individuality, and a society dominated by fear of observation.

The novel presents a dark future where technology companies like the Circle wield immense power, critiquing uncontrolled data collection, algorithmic manipulation, and the erosion of democratic principles through internet dominance.

Mae struggles between her fascination with the Circle's possibilities and her desire for individuality and privacy, forcing her to choose between conforming to the system or fighting for freedom.
