Ordering online

How you buy. You choose a pass (30 days or 24 hours) and press the buy button. You are sent to our payment provider Stripe, where you enter your e-mail address, choose a payment method, tick the box to accept these terms and ask us to start your pass, and press Pay. The contract is concluded when your payment succeeds; we then show your pass and e-mail you a confirmation.

Correcting mistakes. Before you press Pay, the Stripe page shows what you are buying and the total, and you can change your e-mail address or leave with the back arrow or your browser's back button. Nothing is charged until you press Pay.

Storage and access. We keep a record of your purchase (order reference, amount, date and time) in our payment and pass records, but we do not store the concluded contract as a separate document for you to retrieve. Your confirmation e-mail contains the order reference, the price, the key terms and the withdrawal information: please keep it. These terms stay available on this page, and you can ask us at hello@shinobitools.com if you need them again.

Language. The contract can be concluded in English.

The service

StemGrab is a free online tool that separates an audio file into stems (vocals, drums, bass, guitar, piano, other, plus a derived instrumental) using AI. It is provided "as is", without warranties of any kind. Separation quality varies with the source material. There is also an optional paid month pass, described below; the free tool is not a trial and does not expire.

Fair use

• Only upload audio you have the right to process. You are solely responsible for what you upload and for how you use the resulting stems.
• Don't abuse the service: no automated bulk scraping, no attempts to overload the GPU queue, no circumventing rate limits.
• We may block traffic that threatens the stability or legality of the service.

The Pro month pass

Everything described above stays free. Alongside it we sell an optional month pass for €5. It is a one-off purchase: there is no subscription, nothing renews, and nothing is charged again.

• It lasts 30 days, counted from your first track, not from the moment you pay. Buy it tonight and start tomorrow; the clock only begins when you actually split something. An unused pass stays claimable for 90 days, after which it expires unused.
• A pass lives in the browser you bought it in. There are no accounts here, so it is stored locally in that browser and sent along with your requests. It will not appear on a second device, in a different browser, or in private-browsing windows, and clearing your site data removes it. If you lose a pass that way, mail us. See below.
• What it changes: longer tracks, more at once, all stems as MP3 or WAV, the play-along mixes and practice tools, results kept for 24 hours instead of 45 minutes, priority in the queue and no ads. It does not change the separation quality: the free tool and a pass run the same model on the same hardware.
• Payment is processed by Stripe (Stripe Payments Europe, Ltd.). We are the seller: VAT is included in the price and accounted for by us, and we email you a receipt after payment. We never see or store your card details.

Refunds. If the tool didn't do what this page says it does, mail hello@shinobitools.com with the order reference from your confirmation email and we will refund you: we would rather return €5 than argue about it. If the service is unavailable for a meaningful part of your 30 days, ask and we will extend the pass or refund it. Separately from all of this, a pass is a digital service that starts the moment you use it. If you are a consumer, the statutory right of withdrawal applies to a pass and takes effect when you submit it; here is how to exercise it. A pass you have not started can also be refunded within 14 days of paying, as set out in our Refund Policy.

Copyright

Uploading a track does not transfer any rights to us, and separating a track does not give you rights you didn't already have. Publishing stems, covers or remixes of copyrighted recordings may require permission from the rights holders. The tool is intended for lawful uses such as practice, karaoke with permitted material, DJ transitions, accessibility and work on your own recordings.

Liability

To the maximum extent permitted by law, StemGrab is not liable for any damages arising from use of the service, including loss of files or claims relating to uploaded content. Files are processed automatically and deleted shortly after; keep your own originals.

Changes

These terms may be updated; the date above reflects the latest version. Continued use after a change means you accept the updated terms.
