What methods are available to download private Instagram Stories without alerting the account owner, and how can users ensure that their actions remain completely anonymous throughout the process?

Hi. I was also looking for a similar solution. Try Private Instagram Stories Downloader. It is a secure browser tool that allows you to view and download private IG stories without logging in or notifying the user. No app installations, no traces. It works on both public and private profiles completely anonymously.

I like that it does not require logging in or installing. It definitely makes me feel more secure. I will check it out and see how it handles private accounts.
