As already noticed in the comments and another answer, you need to train the binning algorithm using training data only, in such a case it has no chance to leak the test data, as it hasn't seen it. But you seem to be concerned with the fact that the binning algorithm uses the labels, so it "leaks" the labels to the features.

WebA more representative bin width would be one that looked as if the bins had not been chosen on the basis of the data. That's more useful for evaluating the histogram in any context … WebBinning, also called discretization, is a technique for reducing the cardinality of continuous and discrete data. Binning groups related values together in bins to reduce the number of distinct values. Binning can improve resource utilization and model build response time dramatically without significant loss in model quality.
