Once you have recorded a total of 6 seconds, the app automatically stitches all the clips together into a single video file. This is purely a camera utility. There is no external server, no account login, and no cloud tracking. Videos are stored locally on your device. You can easily forward them to instant messengers, email, or social networks using the built-in Android share functionality. Artistic effects: The selfie camera may record upside-down on certain devices. This is definitely not a bug but an artistic choice.
