Unfortunately, you can't really tell if someone screen records your story. Platforms usually don't provide such a notification. It's also a complex technical matter to detect screen recording without interfering with users' normal device usage. Some apps claim to be able to prevent screen recording, but in reality, determined users can often find ways around these restrictions. So, in short, it's very difficult to know if your story has been screen - recorded.
Instagram doesn't notify you directly if someone screen records your story. So, no, you can't really see if someone has screen - recorded it in a straightforward way.
I don't think there's a direct way to know for sure. It's kind of hard to tell if someone is doing that without any specific indicators or notifications.
It's not straightforward to figure out. There's no standard way to be notified. However, if someone is acting strangely or seems overly interested in your story in a way that's out of the ordinary, it could be a hint.
