Diagnostics

This page lists each thing Vantage Player sends to LTC Labs. The short version: a once-a-day update check, launch and close, optional watch and folder events, and crash reports if playback or the app fails. No file paths, no filenames, no video content.

Events

Event	When	What is in it
app_launched	Startup, always	How it was started, and whether a file was opened (yes or no)
app_closed	Closing, always	Session length in seconds
playback_failed	A video fails to decode, always	Error code, codec, container
video_opened	A video watched for about 3 seconds (optional)	Container, codec, duration, pixel size. Videos you skip past are not reported.
folder_navigated	Next or previous (optional)	Direction and how (key, swipe or button). A quick run of next presses is one event.
snapshot_saved	Ctrl+S (optional)	Width and height of the saved image only

Delete video and Copy to folder send no events.

Where it goes

• The update check goes to https://www.ltclabs.dev/api/app/update-check, at most once per 24 hours.
• Crash reports go to https://www.ltclabs.dev/api/app/crash.
• Usage events are sent in batches to https://www.ltclabs.dev/api/app/telemetry, when you close Vantage Player and every 30 minutes while it is open.

What is never sent

• Video or audio content
• File paths, filenames, or folder names
• Subtitle text
• Resume positions, recent-file lists, or copy-to folder lists

Turning it off

Settings → Send anonymous usage data (on by default) stops the optional events. Crash reports and the once-a-day update check stay on so we can fix decoder and startup failures.

The machine is identified by a SHA-256 hash of the Windows MachineGuid. The original value never leaves the PC. There is no account.
