Terms of use

Last updated: 11 November 2026

These terms of use (the "Terms") govern the use of the ostone.app website, your account and the Ostone software. By creating an account or installing the software, you accept them. Purchases (subscriptions and gift cards) are also governed by the terms of sale. This text is a translation of the French version, which prevails if the two differ.

1. Who we are

Ostone is published by the person or company identified in the legal notice, referred to as "Ostone" or "we" in this text.

2. The service

Ostone is voice recording and mixing software for Windows 10 and 11. It comes with a website, an account and optional online features (project sharing, beat generation, connecting AI assistants).

  • The software exists as a Free plan and as paid plans, described on the Pricing page.
  • The software evolves: we may add, change or remove features. We do not remove an essential feature of a paid plan during a paid period without telling you.
  • Features marked "Beta" or "Coming soon" are still being worked on. They may change or contain defects.

3. Your account

  • You need a valid email address. Sign-in uses a link or a code sent to that address, with no password: keep access to your mailbox to yourself.
  • An account is personal. It can be used on up to 3 computers, which you manage from your account page.
  • You must be at least 15 years old, or have the agreement of a parent or legal guardian.
  • The information you give must be accurate. Tell us if you think someone else is using your account.

4. Your licence

We grant you the right to install and use the software, for personal or professional purposes, within the limits of your plan. This right is personal, non-exclusive and cannot be transferred.

You agree not to:

  • resell, rent or distribute the software or access to your account;
  • bypass the limits of your plan, the rights checks or the technical protections;
  • decompile or modify the software, except where the law expressly allows it;
  • use the service for an illegal activity or to harm others.

5. Your creations belong to you

  • You remain the sole owner of your music, your voice, your lyrics and your projects. Ostone claims no rights over them and takes no royalties on what you create, whatever your plan.
  • Your projects are saved on your computer. We have no access to them. The software saves them automatically, but you remain responsible for your own backups.
  • You are responsible for the content you import (beats, samples, texts): make sure you have the right to use it.
  • When you use a generation feature, for example to create a beat, you may use the result in your projects. We do not guarantee that this result is unique, or that it can be protected by copyright.

6. Sharing and working together

When you share a project, you choose who is invited and their rights. You are responsible for what you share. Sharing unlawful content or harassing other users is forbidden. If abuse is reported to us, we may remove an access or suspend an account.

7. AI assistants

The software lets you connect AI assistants provided by other companies. You choose that service and the rights you grant it in Settings, and you can withdraw them at any time. These services have their own terms: we are not responsible for how they work or for their answers.

8. Availability

  • The software works offline. Your plan stays active for 14 days without an internet connection; after that, you only need to reconnect.
  • We do our best to keep the site and the online features available at all times, without being able to guarantee it. They may be interrupted for maintenance or for a reason beyond our control.
  • Updates are offered regularly. Some may be required to keep using the online features.

9. Referral

  • When someone subscribes through your link, you each receive one free month after their first paid month.
  • The reward is granted 14 days after that payment. It is cancelled if the payment is refunded.
  • You can receive up to 12 free months per year.
  • Referring yourself is forbidden, for example with a second account, the same payment method or the same computer.

10. Intellectual property

The software, the site, the Ostone name and logo, the texts, the visuals and the covers generated by the software are protected. Apart from the licence described in section 4, these Terms transfer no rights over these items to you. Items provided by third parties (icons, fonts) remain subject to their own licences.

11. Suspension and end of the account

  • You can delete your account at any time from your account page, under Privacy. Your subscription is then cancelled and your data is erased as described in the privacy policy. Your projects stay on your computer.
  • We may suspend or close an account in the event of a serious breach of these Terms (fraud, bypassing protections, unlawful use). Except in an emergency, we first warn you by email so that you can explain or fix the situation.

12. Liability

  • If you are a consumer, you benefit from the legal guarantees set out in the terms of sale. Nothing in these Terms limits them.
  • We are not liable for the loss of projects saved on your computer, for a failure of your equipment or for an interruption of your internet connection.
  • If you use Ostone in a professional context, our liability is limited to direct and foreseeable damage, up to the amounts you paid us over the last 12 months.
  • None of these limits applies in the event of gross negligence, wilful misconduct or personal injury.

13. Personal data

How your data is processed is described in the privacy policy and on the Cookies page.

14. Changes to these Terms

We may change these Terms, for example when the service evolves or the law changes. For a significant change, we will let you know by email or on the site at least 30 days before it takes effect. If you disagree, you can delete your account before that date.

15. Governing law and disputes

These Terms are governed by French law. If you are a consumer living in another country of the European Union, you keep the protection of the mandatory rules of your country.

If something goes wrong, write to us first at [email protected]: we always look for an amicable solution. Consumers may also use a mediator free of charge, as set out in the terms of sale. Failing agreement, the dispute is brought before the court that has jurisdiction under the legal rules.
