Vantage Player telemetry

Last updated: 3 August 2026

What Vantage Player sends to LTC Labs. Short version: a once-a-day update check, launch and close, optional watch and folder-nav events, plus crash reports if playback or the app fails. No file paths, no filenames, no video content. Optional usage data is off with one Settings toggle. Crash reports stay on so we can fix decoder failures.

Events

Event	When	What is in it
app_launched	Startup, always	Launch source, whether a file was opened (bool)
app_closed	Window closing, always	Session length in seconds
playback_failed	Decode error, always	Error code, codec, container
video_opened	Watched ~3 s (optional)	Container, codec, duration, pixel size. Skimmed files do not emit.
folder_navigated	Prev/next, coalesced (optional)	Direction and method (key / swipe / button). A burst of arrows is one event.
snapshot_saved	Ctrl+S (optional)	Render width and height only

Update check: at most once per 24 hours to /api/app/update-check. Crash reports go to /api/app/crash. Batched usage events go to /api/app/telemetry.

What is never sent

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

Opt-out

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