Your videos don't live on our servers
Capinsta holds your uploaded video and generated captions only while you are actively editing. After a period of inactivity, everything is automatically deleted — the video, captions, transcripts, and exports. We don't keep your media longer than necessary.
Remember to download your export before leaving the editor.
