Terms of Service

Last updated: March 2026

What Oto is

Oto is a browser-based DJ controller and music mixing tool. It runs in your web browser and processes audio locally on your device. Some features optionally connect to external services (authentication, cloud storage, AI processing).

Using Oto

Oto is free to use. You don't need an account to use the core DJ controller — just open the app and load your music. An account (email sign-up or Google sign-in) enables additional features like cloud sync and mix sharing.

Your content

You retain all rights to your music, mixes, and any content you create with Oto. We don't claim ownership of anything you produce. When you share a mix publicly, you're granting other users permission to listen to it through Oto's sharing features.

You are responsible for ensuring you have the right to use any music you load into Oto. We don't monitor, review, or police the audio content processed through the application.

Acceptable use

Don't use Oto to:

The app is provided as-is

Oto is provided "as is" without warranties of any kind. We don't guarantee that the app will always be available, error-free, or that your data will never be lost. Audio processing runs locally in your browser — performance depends on your device and browser.

We recommend keeping backups of any important recordings or set plans outside of the application.

Payments and support

Oto is free. If you choose to support the project financially, payments are processed by Stripe. Support payments are voluntary and non-refundable — they're a way to support ongoing development, not a purchase of specific features or services.

Changes to these terms

We may update these terms as the product evolves. Significant changes will be noted on the website. Continued use of Oto after changes are posted constitutes acceptance of the updated terms.

Open source

Oto's source code is available on GitHub under the MIT License. This means you can view, fork, modify, and redistribute the code. These Terms of Service govern your use of the hosted version at useoto.io.
