So, while it is possible to back up your snaps before deleting your Snapchat account, this kind of function doesn’t exist for third-party apps. This is due to the inherent transience of the app. Dedicated third-party apps, which can be found in abundance in the app store and on Google Play, can help. Since a large data leak in October 2014, however, Snapchat is trying to remove applications like “Snap-Hack” from the store offerings at regular intervals. The basic rule is: Use at your own risk. Most third-party apps quickly turn out to be fraudulent, and in the worst case you risk having your Snapchat account blocked by using them.
Of course, you can also use the short time before an image disappears to take an awkward screenshot of it. However, this has the disadvantage that your contact will be informed about it. By using a common recorder app (for example, the Apowersoft Screen Recorder on Android), you can secretly record videos from your smartphone screen. Since processed data is also temporarily stored in your phone’s cache, certain apps and applications even allow you to restore deleted images and videos.
