Offline Study
Encrypted offline downloads, unlocked by your students only
Students download videos, PDFs and audio for offline study — every file AES-256 encrypted at rest, keys stored only in the device keychain, and unreadable outside your app. Built for weak-network areas and power cuts.
Offline convenience, zero piracy risk
Students study anywhere — and your paid content stays locked to their device, not shareable to the next WhatsApp forward.
Videos, PDFs and audio, offline
Students download lessons once and study anywhere — bus rides, power cuts, weak-network hostels. Downloads resume cleanly and live in a dedicated Downloads screen.
AES-256 encryption at rest
Every downloaded file is encrypted with AES-256 on the device — the media on disk is ciphertext, not a video file anyone can open or share.
Keys live only in the keychain
The per-lesson decryption key is stored in the device's secure keychain — never in the file, never on disk. Copy the file off the device and it's unreadable.
Plaintext never persists
Playback decrypts to a temporary cache file that is deleted when playback ends — a decrypted copy of your content is never left sitting on the device.
Sandboxed, unshareable files
Downloaded files are opaque encrypted blobs inside the app's sandbox — invisible to other apps, files managers and file sharing. Piracy stops at the filesystem.
Offline-first UX built in
The app detects connectivity, tells learners what's available offline, and keeps progress tracking working — offline study feels first-class, not bolted on.
What happens when a lesson is downloaded
Student taps download
Any lesson — video, PDF or audio — can be saved for offline study from the lesson screen in your branded app.
Encrypted on the device
The file is encrypted with AES-256 in 4 MB chunks before it touches disk — what's stored is ciphertext, not media.
Key sealed in the keychain
The per-lesson key is written to the device's secure keychain — never into the file, never alongside the media.
Study offline, anywhere
Learners open the lesson without internet; the app decrypts only what's playing, only for them.
Cache wiped after playback
The temporary decrypted cache file is deleted when playback ends — plaintext never persists on the device.
Progress syncs back
Completions made offline sync to your dashboard on reconnect — analytics stay complete for offline-first students.
Offline download FAQs
+Can students download videos for offline study?
Yes. Learners download videos, PDFs and audio from your courses to their device and study without internet. Downloads live in a dedicated Downloads screen in your branded app, and lesson progress keeps tracking even while offline.
+How are downloaded files protected from piracy?
Every downloaded file is encrypted with AES-256 on the device before it touches disk. The decryption key lives only in the device's secure keychain — never in the file itself. Downloaded media is an opaque encrypted blob inside the app sandbox: other apps, file managers and sharing can't read it, and a file copied off the device is useless.
+Is a decrypted copy of the video left on the device?
No. Playback decrypts to a temporary cache file that is deleted as soon as playback ends. The plaintext version of your content never persists on the device — only the encrypted blob does.
+Do downloads work when the network is weak, not just absent?
Yes. The app is offline-first: it detects connectivity, shows learners what's available offline, and keeps study working through power cuts and weak-network hostels — the exact conditions most Indian coaching students study in.
+Does offline study still track course progress?
Yes. Lessons completed offline are tracked in the app and sync back to your academy dashboard when the device reconnects — so your per-learner analytics stay complete even for students who study mostly offline.
+Why is encrypted offline download better than plain downloads?
Plain downloads turn your paid content into a shareable video file the moment it lands on a device. Encrypted downloads keep the file as ciphertext with the key locked in the device keychain — students get the offline convenience, pirates get nothing.
