Teach live. Sell recorded. Never get pirated.
Your course leaking to a Telegram channel is the fear that keeps Indian educators on someone else's platform. Sutron answers it with real protection — decryption in memory only, screenshots blocked, every copy watermarked.
The DRM shield
LivePremium PDFs decrypt in RAM only — plaintext never touches disk. Screenshots are blocked and a forensic watermark ties every frame to the viewer.
You choose the protection
LiveTwo tracks per product: Regular (the buyer owns the file) or Encrypted Premium. Protection is your call, not ours.
Course builder
LiveA 5-step wizard — basics, format, content, delivery, pricing — with a module and lesson editor, announcements and a classmates roster.
Live classes
LiveScheduled recurring sessions with a lobby, host controls and entitlement-gated join — only enrolled students get in.
Interactive learning
LiveQuizzes, stitched-paper certificates, skill trees and learning streaks that respect your students' attention.
Reading that follows you
LiveBookmarks and per-page notes sync across devices — stored encrypted, because annotations of protected content are content too.
Free previews that sell
LiveShare preview pages or a trailer without ever releasing the key material. The preview is a separate unencrypted object.
Spaced repetition & more
SM-2 review scheduling, breakout rooms, live transcription and SCORM import are on the roadmap.
Can students download my videos?
Only if you allow it. Protected video streams through an encrypted device-local path and never lands on disk as plaintext. Downloads exist only for content you explicitly mark downloadable.
What stops screen recording?
On Android, protected screens set FLAG_SECURE, which blanks screenshots and recordings. Every playback also carries a forensic watermark, so a camera-pointed-at-screen copy identifies its source.
Do certificates mean anything?
Certificates are issued against completion records and verifiable by anyone with the certificate link.
Can I teach live without another app?
Yes — live classes are built in, with scheduling, a lobby and host controls. Students join from the course page.
