It`s legal to use downloaders to save videos. Moreover, it is also super convenient! In the application, all public profiles that you see share public content. If you scroll through the profiles, you will see that it’s a common practice in the community to export someone else`s videos and share them on your profile.
At the same time, the downloaded video should be flagged if you share it on your profile. Do not pass off copyrighted content as your own, it can bring you into disrepute.
Do one of the following:
Mention the content creator in the caption.
Put a tag on the author`s account on the photo.
Write “source unknown” if you are not sure who the author of the video is.
