Privacy policy
Last updated July 26, 2026
The short version
wh3.ninja does not require an account and does not sell personal information. Your imported Steam ownership list, display preferences, filters, and price region are stored in your browser so they remain available on later visits.
Steam library imports
When you import ownership data, the site keeps only the recognized Steam App IDs needed to compare games and DLC. This information is stored locally on your device using browser storage. It is not uploaded to wh3.ninja, and you can remove it at any time from the Steam library sync dialog.
Local preferences
The selected price region, catalog filters, grouping mode, name visibility, and ownership-dimming preference may be saved in local storage. These values stay on your device and can be cleared through your browser settings.
Requests and third parties
The site requests regional Steam prices through its own price endpoint. Opening a Steam, SEGA, wiki, IsThereAnyDeal, or support link takes you to that provider, whose own privacy policy applies. The hosting provider may process routine technical logs such as IP address, user agent, requested URL, and request time for security and reliability.
Contact and changes
This policy may be updated when the site’s data handling changes. Questions can be raised through the project’s public feedback channels.
