Is having a Roblox account tracker game allowed?

So I thought of a game that would tell you everything about a Roblox account. For example when you type the Roblox username or the user ID. It tells you everything that could be told about the one account. So would that be allowed on Roblox?

Of course! Anything that can be retrieved from API is meant to be used… except for country via LocalizationService.

Join date (caluclated via AccountAge), display name, etc. is allowed, since this is public info.
