Snapchat doesn’t have a built-in option to save someone else’s story without them knowing. If you take a screenshot or screen record, Snapchat will usually send a notification. Some people try using screen recording apps or third-party tools, but these can be risky and may break Snapchat’s rules. The best and safest way is to respect privacy and ask the person to share it with you directly. Always think about how you’d feel if it were your story being saved without permission.
