Hard to copy.
Easy to watch.
Encrypted lectures, screen capture blocked, and every frame watermarked with the name of the student watching it — so a course you spent a month on cannot be re-sold in an afternoon.
- No downloadable file
- Watermarked per student
- Device limits
Four layers, all on by default
Not a plan upgrade and not a checklist to work through — this is how video is served on the platform.
Layer 1
Encrypted delivery
Lectures are never served as a plain file. There is no URL to paste into a downloader.
Layer 2
Capture blocked
In your app the screen goes black to a screenshot or a screen recording.
Layer 3
Live watermark
The viewer's own name and number, drifting across the frame so it cannot be cropped away.
Layer 4
Device limits
One purchase, a fixed number of devices. A shared password stops being worth sharing.
Protection you can actually operate
Blocking a download is the easy part. What matters afterwards is knowing when something is wrong and being able to fix it in a click.
Links that expire
Every play is authorised for that student, on that device, for a few hours. A copied link is dead on arrival.
Traceable to one student
If a lecture does turn up in a group, the watermark says whose account it left from.
Revoke in one click
Reset a student's devices or cut their access outright, without touching anyone else's.
Works on the app and the web
The same protection whether they watch on your Android app, an iPhone or a laptop.
PDFs too, not just video
Notes get the same treatment — read in-app, watermarked per student, never downloaded.
You can see it working
Who watched what, from how many devices, and which accounts look like they are being shared.
Upload, watch, monitor
Three moments, and you only have to be present for the first.
Step 1
You upload
The lecture is encoded and stored encrypted. No original file is ever served.
Step 2
They watch
Authorised per student, per device, watermarked as it plays.
Step 3
You watch the watchers
Device counts and viewing history, so a shared account is visible before it costs you.
What piracy actually costs a teacher
Not the one student who copied it. The batch that never had to buy it, and the year after that.
The leak is the business risk
A course that reaches a forwarding group has not lost one sale — it has lost the batch, and every batch after it that would have paid.
One login, one student
Account sharing is the quiet version of piracy: four friends, one fee. Device limits and watermarks are what end it without accusing anyone.
Worth recording properly
Teachers under-invest in production because they expect to be copied. Protection is what makes the good version worth making.
