What circumstances would someone be able to connect to a network and upload large files to arbitrary websites, but where the consequences of being caught are so severe that they need to worry about an adversary recovering deleted files? Because if leaving no traces was really important to me, I probably want to use a 100% air-gapped device, but my impression is that your app requires internet to upload the completed video. Even if you're able to delay the upload until later, if you were willing to risk "life-or-death" to record it, I'm not sure that you'd want to just leave it in RAM where a browser crash or a dead battery could delete it forever. Personally, using something like steganography or deniable encryption [0] seems like a better solution to this problem.
