How to Send View-Once Media on Telegram: Ephemeral Self-Destruct Timers, Anti-Screenshot Protections & One-Time Playback
Share confidential photos, voice notes, and video messages with absolute privacy. Discover Telegram's View-Once media mode, providing single-playback enforcement, hardware-level anti-screenshot shielding, and automatic cryptographic wiping from device caches.

Official demonstration: Tapping the '1' circle icon before sending photos, voice notes, or video messages to enforce permanent one-time playback.
Strict Single Playback
Photos and voice notes vanish forever the instant the viewer closes the preview window or audio playback concludes.
Anti-Capture Shields
Hardware-level OS blocks on Android (FLAG_SECURE) and automated sender alerts on iOS prevent unrecorded capture.
RAM-Only Decryption
Decrypted media buffers reside solely in volatile graphics RAM, bypassing flash disk cache to block file-carving forensics.

CRYPTOGRAPHIC EPHEMERAL PIPELINE
Under the Hood: MTProto View-Once TTL & Memory Sanitization
Unlike standard messages stored in your encrypted cloud backup, View-Once payloads enforce strict ephemeral constraints across Telegram's MTProto transport layer:
shield_locked
InputMediaTTL RPC Protocol: When flagged as View-Once, the client invokes
messages.sendMedia with ttl_seconds = 0 and view_once = true. The server issues a disposable encryption key bound to that specific delivery sequence.
memory
Volatile Buffer Zeroing: As soon as the recipient taps the screen to dismiss or the audio completes, the client executes an in-memory byte wipe (zeroing memory pointers) and instructs local SQLite indexes to prune message references.

WindowManager.LayoutParams.FLAG_SECURE, producing solid black rectangles on external recorders and disabling the Android screenshot shortcut.

OPERATING GUIDE
How to Send View-Once Photos, Videos & Voice Notes
1
Select or Record Media in a 1-on-1 Chat
Open any private direct message chat. Tap the Attachment Paperclip to select a photo/video, or swipe up on the mic button to lock voice/video recording.
2
Tap the Circular '1' Icon
In the media editor caption bar (or next to the locked voice note waveform), locate the circular '1' icon. Tap it so the icon highlights in vibrant blue.
3
Transmit the Ephemeral Payload
Tap the Send button. The media delivers with a locked ephemeral badge instead of an open image thumbnail. Once opened by the recipient, it burns forever.

SECURITY & USAGE FAQ
Frequently Asked Questions
Can the recipient forward or save View-Once media?
No. Forwarding, saving to gallery, and copying to clipboard are completely disabled for all View-Once messages across all official Telegram clients.
Does View-Once work in group chats and channels?
No. View-Once media is restricted strictly to one-on-one direct message conversations where strict point-to-point delivery acknowledgment can be verified.
Can View-Once media be restored from local backup or data recovery tools?
No. View-Once files are never committed to unencrypted persistent SQLite database tables or disk cache directories. They reside in volatile RAM and are securely overwritten with zeros upon closure.
