Search positions come from Apple's public Search API — the same results the App Store shows anyone searching that phrase. Chart positions come from Apple's public chart feeds. App names, categories and rating counts come from Apple's public lookup service.
Search volume is the one figure that is not public. It comes from an Apple Search Ads account, which is where Apple reports how much a phrase is searched to advertisers.
We have no access to anybody's App Store Connect, no download data, no revenue data, and no way to see the keyword field you set on your own listing. Anything on this site that looks like private data would be us guessing, which is why there isn't any.
