You generally do not receive a notification when someone screenshots your Instagram post. Instagram does not alert users when screenshots are taken of their public content, including both grid posts and Instagram Stories.
Understanding Instagram's Screenshot Policy
Instagram's policy on screenshots is quite clear and has been consistent: for content shared publicly on your profile or through your Stories, the platform does not notify the original poster if someone takes a screenshot or screen recording.
This applies to various types of content you share:
- Grid Posts: If someone screenshots a photo or video you've posted to your main Instagram feed, you will not be informed.
- Instagram Stories: When a user captures a screenshot of your active Instagram Story, the platform does not send a notification to you.
- Video Posts (Screen Recordings): Similarly, if someone screen records a video you've uploaded, whether on your grid or as part of a Story, there is no notification feature for this action.
In essence, if content is visible to the public (or your selected audience for Stories), Instagram considers the act of viewing and capturing it through a screenshot or screen recording as a private action of the viewer, without notifying the creator. This means there's no direct way to know if your public Instagram content has been screenshotted by another user.
