I have a Steam account. I just want to sign into it myself and add the Steam key. Nothing was said about Itch getting involved in my Steam account, why should I allow it? I do not want my privacy violated by paperash, itch or anybody else. If you think that isn't happening, then you are blinkered.
Here is the warning I get from Steam:
By signing into paperash.itch.io through Steam:
- the site will be able to identify you within the Steam Community and retrieve public info such as your stats and achievements.
- a unique numeric identifier will be shared with the site, rather than your Steam login credentials.
- basic information about your Steam account will be shared with a third-party web site. See our Privacy Policy for more information.
