Vyera — Privacy

Last updated 15 September 2026 · applies to Vyera 1.6.0 and later

Vyera is an ambient edge-glow music visualizer for Windows. It is original, independent software (concept inspired by ambient screen lighting apps; no third-party code, assets, or branding).

The short version: your audio never leaves this PC. The only thing that does is the name of the track you are playing, sent to look up its lyrics — and you can switch that off.

• No microphone — ever. Vyera listens to what Windows is playing (WASAPI shared-mode loopback, a digital copy of your speaker output). It cannot hear your room, and it never asks for microphone permission.
• All audio analysis is local. The audio stream is reduced to a handful of numbers (bass/mid/treble energy, loudness, beats) in memory, ~60 times a second. Audio is never recorded, stored, or transmitted.
• No telemetry, no analytics, no accounts. Vyera never reports how you use it, never sends usage or crash data anywhere, and requires no sign-in. The only requests it ever makes are the lyric lookups described below, and the Spotify calls you opt into.
• Album artwork stays local. Track info and artwork come from Windows' own "now playing" service and are processed entirely on your PC.
• Spotify is optional and off by default. If you enable it, Vyera talks only to Spotify's official API using your own app credentials (PKCE — no app secret exists anywhere). Sign-in happens in your browser; Vyera never sees your password. The refresh token is stored on this PC only, encrypted with Windows DPAPI for your user account, and is deleted on uninstall.
• Lyric lookup is on by default, and it is the one thing that leaves your PC. Online lyric lookup (Lyrics tab) is enabled out of the box, and it runs whenever something is playing — including while the lyrics display itself is switched off, so that words are ready the moment you open the view. Each lookup sends only the identity of the track: the Spotify track id or ISRC when Spotify is the player, otherwise artist, title, album and duration. It is sent to the lyric services Vyera uses — Musixmatch, then LRCLIB. No audio, no listening history, no account, nothing that identifies you or your machine. Results are cached in %AppData%\Vyera\Lyrics\cache, so a track is looked up once and never again.
• If you would rather nothing left the machine at all, turn off "Look up lyrics online" on the Lyrics tab. Vyera then uses only .lrc files in your own Lyrics folder, and makes no network requests whatsoever.
• Logs are local and bounded. A small troubleshooting log (%AppData%\Vyera\overlay.log, capped ~1 MB) records app events; it may include the titles of tracks you played (for palette debugging) but never audio, tokens, or credentials. It is never uploaded.
• The diagnostics report contains no secrets. "Copy diagnostic information" includes hardware, display and app-state facts only.
• No admin rights, no drivers, no injection. Vyera is a normal per-user app: it draws a click-through overlay, and never touches other processes, games, or anti-cheat systems.
