Is knowing a winning product from other online stores via applications that display data such as number of orders and total profits, knowing that this data is not publicly displayed but is only used to find the winning product, considered the forbidden spying in Islamic law?

Gathering information about online stores does not fall under the blameworthy espionage prohibited by religious law, as stated in the verse: "And do not spy." This is because forbidden espionage targets people's private matters, faults, and secrets, and it involves searching for people's flaws and secrets that they do not wish to be revealed, whereas gathering information about online stores is not of that nature.
