It depends on the platform. On some social media platforms, your favorites story may be private by default and only you can see it. But on others, there could be settings that might make it visible to certain people, like your friends or followers. So, always check the privacy settings of the particular platform.
No, generally people cannot see your favorites story. Usually, these are personal selections that are meant to be private. However, if there is a bug in the system or if you accidentally change your privacy settings to public, then there is a slim chance someone might be able to see it. But in normal circumstances, it's private.
In most cases, people can't see your favorites story without your permission. The concept of favorites is often designed to be a personal feature for your own convenience, like bookmarking things you like. But if you are using a shared device or if the app has some sort of family - sharing or group - access feature enabled, then it's possible for others to see it. For example, on some e - book apps, if you have family sharing on, family members might be able to see the e - books you've marked as favorites. But for most mainstream social media and apps, it's private.
