SteamDB is a free, independent database covering the entire Steam catalog. Player charts, price history across all regions, update histories, and detailed data for every product — kept current through fast, automatic updates.
Calculator page itself only temporarily caches the data you see on the page when you lookup a profile for up to an hour. We do not store historical changes of your data.
For badges pages, top game owners, and top levels pages we only store and show up to 2000 top public profiles. When a profile is looked up in our calculator, and we see that the profile is private, data about this profile will be deleted.
See this online tool on this webpage.
