This policy explains what we collect and why when you use this site. It has three parts:
If you only use the feedback stream, Parts 1 and 3 are the ones that apply to you.
The site is run by the stream operator ("we", "us"). Questions or data requests: reach us via the stream's Discord or Twitch.
When you log in with Twitch we receive and store your Twitch user ID, username, display name and profile picture. We use them to know which tracks, entries and results are yours. Twitch handles the login itself (OAuth); we only receive those basic profile fields. We may also check and store whether you're subscribed to the channel and at which tier, for subscriber perks.
Tracks you upload go into one library that both battles and the feedback stream use. For each track we store the audio file, the track and artist name you give it, its file type, size and length, and artwork if you add some. A track you upload for one can later be entered in the other.
To protect the stream from dangerously loud files, an upload that goes above full volume (only possible with 32-bit float WAV files) gets a separate, turned-down copy that's used for playback. Your original file is kept unchanged.
The site is not directed to children under 13 (or the minimum age Twitch requires in your region). Don't use it if you are under that age.
We may update this policy; the "last updated" date above shows the latest version. Continued use after a change means you accept the updated policy.
This part covers Music Producer Battle Royale and protobattles (beat battles).
Track recognition ("Shazam-lite"). We create acoustic fingerprints and hashes from uploaded tracks. In battles we use them to detect duplicate uploads, to check whether an entered track matches one already played or a known commercial release, and to flag possible re-uploads for review. This keeps the competition fair.
Cooldowns. We keep a record of which tracks have been played (identified by fingerprint, hash and track details), so the same track can't be entered again until its cooldown has passed. This includes a new export of a track that's still on cooldown.
Fingerprints and hashes are derived from your audio; they are not the audio itself.
If external recognition is switched on, when you enter a track into a battle an acoustic fingerprint (not necessarily the full audio file) may be sent to third-party matching services (for example AcoustID, AudD or ACRCloud), only to identify the track. Their handling of that data is covered by their own privacy policies.
Your submissions, which tracks you entered, votes you cast and received, points, and match and bracket history. Your tracks are played on stream and on the battle pages as part of the competition, with your name, artist name and track name.
We keep fingerprints and hashes for as long as the track is in your library or needed for recognition and cooldowns. Records used to enforce fairness and cooldowns may be kept in de-identified form after you delete the track.
This part covers the feedback raffle: entering the wheel (on the feedback page or with !join in chat), having your track played for feedback, paid line skips and the Hall of Fame.
When you upload a track from the feedback page, our own server makes a fingerprint and hash of it, like every upload to the library. They're only compared with your own tracks: to spot the same file twice in your library, and so a track that's on a battle cooldown keeps that cooldown.
From the feedback stream, your track is never sent to an outside service and never compared with anyone else's music or commercial releases. Entering the feedback raffle runs no recognition checks at all. Those only happen if you enter the track into a battle (Part 2).
Line skip payments are handled by Stripe. Your card details go straight to Stripe and never reach us. We keep your Twitch ID and username, Stripe's payment references, the amount and currency, the payment status, and when the skip was paid for and played. We keep these records for accounting and refunds. Stripe's handling of your payment is covered by Stripe's privacy policy.
If your track is added to the Hall of Fame, your name and the track are shown on the public Hall of Fame page. You can hide all of your Hall of Fame entries from your profile page.
