No, Clipchamp does not have any access to your videos.
The longer explanation:
We never have access to your video files as we actually never upload them to a server for processing. They get processed on your computer and never leave your computer (unless you upload them to Google Drive or any other online provider). The processing of your videos is all happening inside the browser but it basically works like a desktop application with the browser as the platform Clipchamp runs on.
And that's the key difference between Clipchamp and an actual online converter or webcam recorder, an online converter would upload the video to their servers, process it and then you'd have to download it again and hope that they delete the original off their servers again.
In Clipchamp, there is no server-side processing or uploading/downloading of the video. All the files that the app needs to process your video get loaded into the browser behind the scenes and thus all the video recording and processing happens locally on your machine. This means you have full control over what happens with your video files.
When you're done recording and the video appears on the "Hooray we're done" page where you can save or share it, what happens when you click the Save button is that the converted video gets saved to your computer from the temporary browser folder it was stored in behind the scenes (once you save the video or refresh the app, those temp files get deleted).
The browser might still display a message that mentions "downloading" in it, though that's due to it being a standard text that we can't modify unfortunately to say something that would be more accurate in our case, for instance "saving video".
