Most of the time, a person whom you took a screenshot or recording of their content won’t be notified that you did so. The same goes for you too.
Basically, you are safe to screenshot someone else’s profile without them ever knowing about it. This can be very helpful if you quickly want to save. Their contact information or website without having to follow them.
As far as Instagram goes. Regular photo and video posts are seen on users’ profiles, Explore tab, or in the home. Feed are safe from screenshot notifications. However, for direct messages. (A disappearing photo or video message is taken with the Instagram camera). A notification is sent if such a direct message is screenshotted or screen recorded. For anything besides direct messaging. Notification is not sent.
Instagram once spent a few months testing a feature. Where users could see who was taking a screenshot of theirs. Stories but that feature have been removed. There is no guarantee though that Instagram is done. With story screenshot notifications, as there is. Always the possibility that the testing could resume anytime.
One way to taking a screenshot of a post is to use it.
The Instagram built-in bookmarking feature to save images. This allows you to collect several posts and revisit them later. Without the original poster ever being notified. To save a post, simply tap the bookmark icon beneath it. If the original image gets deleted. Your bookmark will fail when. You intend to retrieve the saved post.
To reduce the number of persons freely accessing and screenshotting your Instagram content, you may consider it. Making your profile private, with a private profile, only your existing followers and those requests. You approve can take screenshots. Non-followers won’t be able to see anything except your profile picture and name and this prevents them from accessing and so screenshotting any of your posts, bio information, and stories.
THIRD-PARTY APPS CLAIMING TO NOTIFY YOU OF INSTAGRAM SCREENSHOTS
There are third-party apps that claim to send you screenshot notifications. Instagram puts strict limitations on what Third-party apps can do. This is for privacy and security reasons, therefore no app you install can successfully tell you who is taking screenshots of your content.
If you come across an app claiming to be able to tell you who is taking a screenshot of contents, ignore it and peradventure you have already installed it, then uninstall the app immediately and change your Instagram password just to be safe.
