This is why any good wallet software doesn't reuse addresses. The receiver knows the address, the amounts and change.

They will only know the change from the UTXO that I sent them. So unless you reuse addresses, then your entire balance is still hidden from them.

Surely anyone who receives a payment from you, of any size, will know your address and hence your balance?
