Terms of sale and license

General terms and end user license agreement Last updated 15 October 2026

In plain language

This summary is here to help. The full terms below are what count.

  • You pay once. There is no subscription, no password and no license key: you sign in with the email address you bought with.
  • Your license covers Grit 1.x, including all 1.x updates, on up to two computers you own or control, Mac, Windows or Linux. A future major version may be a paid upgrade; the version you bought stays yours.
  • You may use Grit for private and professional performances, including paid gigs.
  • Only import music you have the right to use. Grit processes it locally on your computer.
  • As a consumer, you have a right of withdrawal. It ends as soon as we deliver Grit: before you pay, you agree that we deliver right away and confirm that you lose your right of withdrawal as a result.

1. Scope and seller

These terms apply to all purchases of Grit through this website and to your use of Grit. The seller and licensor is:

Screen Island GmbH
Falkenstrasse 8
35576 Wetzlar
Germany
[email protected]

Further company details are in the imprint. Terms of buyers that differ from these do not apply unless we agree to them in writing.

You are a consumer if you buy for purposes that are predominantly outside your trade, business or profession. Some provisions, such as the right of withdrawal, apply to consumers only.

2. The product and its price

Grit is downloadable software for Mac, Windows and Linux. The features are described on this website; the system requirements for each platform are on the download page.

Grit is a one-time purchase. The price shown on this website and at checkout is the final price and includes the VAT applicable in your country. VAT is calculated by Stripe Tax from your billing address. There are no delivery costs.

3. How the contract is concluded

The presentation of Grit on this website is not a binding offer. Clicking “Get Grit” takes you to a secure checkout page run by our payment provider Stripe. There you enter your email address, billing address and payment details. Before paying, you can review all entries and correct them at any time using the fields on the checkout page, or go back to leave the checkout without buying.

Before the checkout opens, you tick a box to expressly agree that we begin performing the contract before the withdrawal period ends, by providing the download and your license, and to confirm that you know you lose your right of withdrawal when we begin. Without this agreement, the checkout does not start.

By clicking the payment button on the checkout page, you submit a binding offer to buy Grit. The contract is concluded when we accept your offer by making the download available and enabling activation for your email address after your payment has been confirmed.

The contract language is English or German, depending on the language in which you buy. We do not store the contract text for you to retrieve later. These terms are always available on this page, and you receive a receipt and invoice by email.

4. Payment

Payment is due immediately and is processed by Stripe. You can use the payment methods offered on the checkout page. Some payment methods take time to clear; in that case, delivery follows once the payment is confirmed.

5. Delivery and activation

After your payment is confirmed, you receive a download link on the confirmation page and by email to the address you entered at checkout. The download is also available in your account.

To activate Grit, sign in in the app with your purchase email address and the one-time code we send you. Activation requires an internet connection. Once activated, Grit works offline; a performance never depends on our server. The app checks your license from time to time when it is online.

6. Your license

With full payment, we grant you a non-exclusive, perpetual license to install and use Grit 1.x, including all 1.x updates, on up to two computers (Mac, Windows or Linux) that you own or control, at the same time. The license is personal: it is granted to you as an individual. You may use Grit for private and professional purposes, including paid performances.

You can remove an activated computer in your account or in the app and activate another one instead. We may allow more computers than stated here; your account shows the current number. Future major versions (such as Grit 2) may be offered as a paid upgrade. The version you bought remains usable.

Grit, its code, design and included audio remain the property of Screen Island GmbH and its licensors. All rights not expressly granted here are reserved.

7. What you may not do

  • Share your sign-in, or publish, sell, rent, lend or sublicense the software.
  • Circumvent or disable license activation or the computer limit.
  • Decompile, disassemble or reverse engineer Grit, except where the law expressly permits it (for example § 69e UrhG).
  • Remove copyright or trademark notices.

8. Your music

Grit lets you import, separate, remix and perform audio. You are responsible for having the necessary rights to the audio you import and to any performance, recording or publication you create with it. Grit processes your music locally on your computer; we do not receive, review or store it.

9. Refunds, chargebacks and revoked licenses

If a purchase is refunded, whether through a withdrawal or otherwise, or if the payment is reversed through a chargeback, the license is revoked. A revoked license cannot be activated on any further computer. Because Grit works offline, an existing activation is not switched off remotely; you are no longer entitled to use it and must remove Grit from your computers.

10. Warranty

The statutory warranty rights apply. For consumers, these are the rules for digital products under §§ 327 ff. of the German Civil Code (BGB), including our obligation to provide the updates needed to keep Grit in conformity with the contract for the period you can reasonably expect. Grit is designed for the system requirements stated in section 2; we cannot guarantee operation on other systems or with every audio device or controller.

11. Liability

We are liable without limitation for intent and gross negligence, for injury to life, body or health, under the German Product Liability Act (Produkthaftungsgesetz) and where we have given a guarantee.

For slight negligence, we are liable only for breaches of essential contractual obligations: obligations whose fulfilment makes proper performance of the contract possible in the first place and on whose compliance you may regularly rely. In that case, our liability is limited to the damage that is typical and foreseeable for this kind of contract. In all other cases of slight negligence, we are not liable.

These limitations also apply to the personal liability of our employees, representatives and agents. Keep backups of your music library; this is part of your duty to mitigate damage.

12. Right of withdrawal for consumers

If you are a consumer, you have the following right of withdrawal (Widerrufsbelehrung):

Right of withdrawal

You have the right to withdraw from this contract within 14 days without giving any reason.

The withdrawal period will expire after 14 days from the day of the conclusion of the contract.

To exercise the right of withdrawal, you must inform us (Screen Island GmbH, Falkenstrasse 8, 35576 Wetzlar, Germany, email: [email protected]) of your decision to withdraw from this contract by an unequivocal statement (e.g. a letter sent by post or an email). You may use the attached model withdrawal form, but it is not obligatory.

To meet the withdrawal deadline, it is sufficient for you to send your communication concerning your exercise of the right of withdrawal before the withdrawal period has expired.

Effects of withdrawal

If you withdraw from this contract, we shall reimburse to you all payments received from you without undue delay and in any event not later than 14 days from the day on which we are informed about your decision to withdraw from this contract. We will carry out such reimbursement using the same means of payment as you used for the initial transaction, unless you have expressly agreed otherwise; in any event, you will not incur any fees as a result of such reimbursement.

Early expiry of the right of withdrawal

Your right of withdrawal expires early if we have begun performing the contract after you (1) expressly agreed that we begin performing the contract before the withdrawal period ends, (2) confirmed your knowledge that, by agreeing under (1), you lose your right of withdrawal when we begin, and (3) we have provided you with a confirmation of the contract under § 312f of the German Civil Code (BGB). We begin by providing the download and your license as soon as your payment is confirmed.

End of the withdrawal information.

Note: when you withdraw, your license is revoked as described in section 9. Please remove Grit from your computers.

Model withdrawal form (Muster-Widerrufsformular)

(Complete and return this form only if you wish to withdraw from the contract.)

13. Final provisions

German law applies, excluding the UN Convention on Contracts for the International Sale of Goods (CISG). If you are a consumer, this choice of law does not deprive you of the protection of the mandatory provisions of the law of the country where you habitually reside.

If you are a merchant (Kaufmann), a legal entity under public law or a special fund under public law, the exclusive place of jurisdiction is Wetzlar.

We may update these terms for future purchases. Changes do not affect purchases already made; the terms that applied when you bought remain valid for that purchase.

If any provision of these terms is invalid, the remaining provisions remain effective.
