Well, as of now, if you screenshot an IG story, the person who posted it has no way of knowing. Instagram doesn't have a built - in mechanism to inform users that their stories have been screenshotted. It's one of the aspects that keeps the user experience relatively private when it comes to interacting with stories. You can screenshot a story to save it for later reference, share it privately (although sharing someone else's story without permission might violate Instagram's terms in other ways), or just keep it for yourself, all without the creator of the story being aware.
Typically, they can't. For instance, on Snapchat, which was one of the first to popularize stories, originally there were concerns about screenshot detection. But as of now, for normal stories, if you screenshot, the other person won't be notified. The same goes for platforms like Facebook and Instagram. These platforms prioritize user experience and privacy in a way that doesn't make screenshotting someone's story a privacy - invading act that the original poster can detect easily. But remember, just because they can't see it doesn't mean it's ethical to screenshot without permission if the content is private or personal.
No, Instagram doesn't notify the user when you screen record their story. However, this might be subject to change in the future as platforms often update their privacy and functionality features.
Instagram doesn't have a feature that alerts the user when someone screenshots their IG stories. However, this could potentially change in the future as the platform's policies and features are subject to updates. But currently, you can screenshot without the other person being aware.
On Instagram, the answer is no. There is no way for the person who posted the story to know if you've taken a screenshot of it. This is different from some other features on Instagram, like direct messages where there are read receipts. The lack of screenshot notification for stories is to promote a more open and sharing - friendly environment. But again, it's important to respect others' privacy and content, even if they can't detect the screenshot. For example, if it's a creative work or something personal, it's always better to get permission before screenshotting and using it in any way.
No. Just like with IG stories, Instagram doesn't notify the user when you screen record an IG live session. It allows you to record for your own personal use without the broadcaster knowing.
