Privacy Policy

IronSound collects your account email, name, generation prompts, job status, and the private songs you create so we can run the product. Authentication is provided by Better Auth (email/password and Google). Payment is handled by Polar. Full songs are made with YuE2-3B, self-hosted on IronSound-operated servers, when that engine is available; otherwise they fall back to Google Lyria 3.5. 30-second clips use Google Lyria 3 Clip, and studio WAV masters use Google Lyria 3.5. Lyria output carries an inaudible Google SynthID watermark; YuE2-3B output does not. Each song's license file names the engine that made it. Audio is stored in a private Cloudflare R2 bucket and streamed only to the signed-in owner.

For a full song with vocals, if you don't supply lyrics, we send your prompt to Google Gemini to draft them. Lyrics that only repeat the style prompt count as not supplied. If you write your own lyrics, your prompt is already a lyric sheet, or you ask for an instrumental, that step is skipped.

We do not sell your personal data. We do not make your songs public. When a track is made with Google Lyria (every clip and studio WAV, and full songs that fall back to Lyria), your prompt goes to Google to generate the audio. Polar, the reseller and merchant of record, receives the email and identifiers needed to check out and issue receipts. Pack purchases are one-time and do not renew.

Session cookies keep you signed in. If you buy a credit pack, Polar may set checkout cookies. Password reset emails are sent through Resend. You can delete your account yourself from Settings while signed in. If you cannot sign in, email [email protected] from the address on the account to request deletion of your account data.

Tracks made with Google Lyria carry an inaudible SynthID watermark. Tracks made with YuE2-3B on IronSound-operated servers do not. We log job identifiers, user identifiers, and provider/storage error codes. We do not log MP3 bytes or API keys.
