Edit again: the person responding to reviews clearly doesn’t understand data tracking across apps and websites from other companies, sketchy when your app is doing it and it’s literally disclosed on your product page ha

Very excellent practice! Im not a english person so this helps me a lot by learning all these words and the sentences that included words that are previous lesson practice.
