Terms of Service

You must be 18 or older to create an account. IronSound generates AI music from your prompts. 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. Do not remove the SynthID watermark from Lyria tracks. The license file also states which generator terms apply.

You may use songs you generate, including commercially, subject to the per-song license and these terms. Lyria tracks are also subject to Google Gemini paid API terms. You are responsible for the prompts you submit. Do not attempt to clone a specific artist's voice, submit copyrighted lyrics you do not own, or generate content that violates applicable law.

Credits are spent when a generation starts. If generation fails, your credits go back to your balance (not a cash refund), once per failed run. Pack purchases are one-time Polar checkouts. They do not renew, and there is no subscription. Credits have no cash value and are not transferable. Polar is the reseller and merchant of record. Polar handles payment, receipts, and any payment refund for pack purchases.

Songs are private to your account and downloadable as MP3 or studio WAV from the song page, each with a per-song license (see licensing). Listening does not require a subscription. We may suspend accounts that abuse the service, attempt to share audio URLs publicly, or reverse-engineer the model.

To delete your account, use Settings while signed in. If you cannot sign in, email [email protected] from the address on the account. Deletion removes your songs from our library; Polar may retain billing records as required by law. You can also delete individual songs from the song page.
