It depends on the platform. In general, many platforms like Facebook and Twitter don't notify the user when their story is screenshot. However, some apps might have specific settings or features that could potentially change this, but it's not a common occurrence. So in most situations, it doesn't tell someone if you screenshot their story.
Generally not. Platforms usually don't have a built - in feature to tell someone that their post has been screenshot. For example, on Twitter, there's no such notification. This is because the platforms want to encourage sharing and interaction. If people were constantly notified about screenshots, it might discourage others from sharing interesting posts.
In most cases, the answer is no. Consider platforms like Facebook or Instagram. Their main focus is on sharing content widely. If users were notified every time someone took a screenshot of their story, it might discourage sharing. Also, from a technical perspective, implementing such a feature across all devices and scenarios is quite complex. So, generally, people can't tell if you screenshot their story.
Typically, they can't. Whether it's Snapchat (where screenshotting a story used to be more detectable but now has less strict detection in many cases), Instagram, or Facebook, these platforms do not currently provide a built - in way for the story creator to be informed that someone has taken a screenshot of their story. But, always be aware that technology can change, and new features could potentially be added in the future.
