If you used xHamster's tool to create an account on a partner site, the sharing no longer stops at sign-up information. The policy now allows your personal messages, your username, and details about those messages to be sent to those partner sites and shown there. On an adult site, message content and usernames are sensitive — this can link your identity and private conversations to platforms you may not have looked at closely. The policy does not say who on the other platform can see them or how to turn this off.
“the operation of linked account features across those platforms, including messaging functionality, with the result that personal messages sent or received through your account, together with the associated usernames and message details, may be displayed on the third-party platform(s) and viewed there”
What you can do — Avoid using xHamster's one-click tool to create accounts on other platforms. If you already have linked accounts, check your account settings for a way to unlink them, review what is visible on the partner site, and treat any messages sent through a linked account as potentially public. You can also review the current partner list at https://xhamster1.desi/info/list-of-processors and ask xHamster's privacy contact to stop this sharing.
