We show that energy conservation puts an upper bound on the maximum entropy available to any de Sitter observer. Combined with a general result on the average information in a quantum subsystem, this guarantees that an observer in de Sitter space cannot obtain even a single bit of information from the de Sitter horizon, thereby preventing any observable violations of the quantum no-cloning principle, in support of observer complementarity.9 pages, 2 figures, LaTeX, corrected equation 11High Energy Physics - TheoryAstrophysicsGeneral Relativity and Quantum Cosmologytext
