Vyera — Privacy

Last updated 26 September 2026 · applies to Vyera 2.0 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 a larger cover — and you can switch both off.

• No microphone — ever. Vyera listens only to what Windows is playing. By default that is a digital copy of the sound from the app that is playing your music, or from one app you pick yourself (WASAPI process loopback), so notifications and other apps stay out; if you choose Everything, it is a copy of your whole speaker output (WASAPI loopback). 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 and cover lookups described below, and the Spotify calls you opt into.
• The glow's colours are worked out on your PC. Track info and artwork come from Windows' own "now playing" service, and the palette is computed locally.
• Sharper covers in the lyrics view are on by default. Players hand Windows a small cover image. While the full-screen lyrics view is open on the Artwork backdrop, Vyera asks Apple's public iTunes Search service for a larger copy of the same album cover, sending only the artist, title and album name of the track — no account, no audio, nothing that identifies you or your machine. Covers are cached in %AppData%\Vyera\Covers (the 40 most recent). Switch it off with "Sharper covers in the lyrics view" on the Media tab.
• 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. 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 and "Sharper covers in the lyrics view" on the Media tab. Vyera then uses only .lrc files in your own Lyrics folder, and makes no network requests whatsoever (unless you connect Spotify).

• Timing memory is local. To place words better the second time a song plays, Vyera keeps the moments it heard a voice start in that song — a list of timestamps, no audio and no lyrics — in %AppData%\Vyera\Timing (the 400 most recent songs). It is never uploaded.
• 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.
