Videos you upload to Snatr are encrypted, and the decryption key goes to the decryption module inside the browser, never to the page. That is why download extensions, paste-your-link sites and tools like yt-dlp come away with files that are useless. What encryption does not stop is screen recording, or filming the screen with another phone — and we say so before you subscribe.
We tested it the way download tools work: collected every segment exactly as a tool would, and measured the picture that came out. Without the key it was noise unrelated to the video (10.6 dB); with it, the same video exactly (59.9 dB). The same files — unwatchable without the key.
Apple devices (Safari and iOS) lack the decryption module the platform uses, so they are given a second copy encrypted in a simpler way, so the video plays there normally. Ready-made download tools fail there too, but that copy is weaker against someone technically skilled, and every session that uses it is logged.

Upload them to a platform that encrypts the video and delivers the key to the browser's decryption module, as Snatr does. That shuts out download extensions, download sites and tools like yt-dlp. YouTube and Drive links do not protect against those.
No. The tool can collect the video's segments, but without the key held inside the browser it ends up with useless files.
No, and we say so plainly. Screen recording and filming the screen with another phone both work. Encryption stops downloading, not recording.
Yes, from a copy encrypted differently for Apple devices. Ready-made download tools fail there too, but its protection is weaker against a skilled person.
Encryption stops the video being downloaded. A watermark stops nothing, but makes whoever leaks it identifiable. On live lessons Snatr places a logo and a short code on the picture.
From the course builder: each lesson is either a video you upload or a YouTube link — one or the other. Protection applies to the videos you upload.
