Privacy
Last updated November 10, 2026
Short version: ChorusCue runs in your browser. There's no ChorusCue account and we don't receive your playlists or listening data. The only thing ChorusCue's server keeps is an optional, anonymous shared list of cue times (see "Shared cue fixes" below), which you can turn off.
What ChorusCue accesses
When you sign in with Spotify, you approve these permissions:
- Read your playlists (private and collaborative) and your Liked Songs, so ChorusCue can list your songs.
- Read and control playback, so ChorusCue can see what's playing and jump, pause, seek and set volume on your Spotify device.
- Your basic Spotify profile ID, so ChorusCue can tell which playlists are yours.
ChorusCue uses this only to show your playlists and control playback when you click something. It doesn't post, change your playlists, or share anything.
Where your data lives
- Your Spotify sign-in (access and refresh tokens) is stored in your browser's local storage on this device. It goes only to Spotify's own servers (accounts.spotify.com and api.spotify.com).
- Your saved cues, chorus guesses, last playlist and preferences are also stored only in your browser's local storage.
- Apart from the shared cue fixes described below, nothing is sent to or stored on a ChorusCue server.
Shared cue fixes
To make chorus cues better for everyone, ChorusCue keeps a shared list of cue times that users have saved. The switch is Share my cue fixes at the top of the app. It's on by default and you can turn it off at any time.
- What's sent: when you save your own cue for a song (Save, or Save spot), ChorusCue sends the song's Spotify track id, the cue time, which cue it is (the chorus) and the song's length. Removing your cue removes your vote.
- How we check it's a real person: the request carries your Spotify sign-in token. ChorusCue's server uses it once to ask Spotify for your account id, then forgets the token. The token itself isn't stored, logged or used for anything else, and the server makes no other Spotify calls.
- What's stored: your vote is filed under a one-way scrambled code (a keyed hash) made from your Spotify account id, so we can count one vote per person per song and apply rate limits. We don't store your Spotify id, name, email, IP address or token. (To stop abuse, the server counts rejected sign-ins per scrambled code made from the IP address, also a one-way keyed hash.) Per song we keep each scrambled code's cue time, song length and when it was saved.
- What others see: only the combined result per song, such as "chorus at 1:03, 3 users agree". Never who voted.
- Where: the shared list is stored with our host, Netlify (Netlify Blobs).
- Reading shared cues: when you load a playlist, the app asks ChorusCue's server for shared cues for songs that aren't in the built-in list, sending only their Spotify track ids. This happens even with sharing turned off, because it only reads.
- Deleting: remove your saved cue in the app to withdraw that vote, or email us to have your votes removed.
Lyrics lookups (lrclib.net)
For songs with no cue data, your browser asks the free lrclib.net service for that song's timed lyrics, sending the song title, artist, album and length. lrclib.net sees that request and your IP address, like any website. Its handling of requests is governed by lrclib.net, not by ChorusCue. This happens automatically when you load a playlist that has songs without cue data, and when you click "Guess chorus" or "Guess missing choruses".
Hosting
The site's host may keep standard web server logs (such as IP address, browser type and pages requested) for security and operations. ChorusCue doesn't use analytics, ads or tracking cookies.
Disconnecting and deleting your data
- Click Sign out in the app to delete your Spotify sign-in from this browser.
- To remove ChorusCue's access to your Spotify account entirely, go to spotify.com/account/apps and click Remove access next to ChorusCue.
- To delete your saved cues and guesses too, clear this site's data in your browser settings.
Beta access emails
If you email us to join the beta, we use your email address only to add you as a tester in Spotify's developer dashboard and to reply to you. We'll remove it when you ask.
