Terms of Service

Last updated: June 11, 2026

These Terms of Service (these “Terms”) govern your use of Sotto, a dictation app for macOS (the “App”), and its official website (the “Site”). The App is provided by an individual developer (the “Developer”).

By downloading, installing, or using the App, you agree to be bound by these Terms. If you do not agree, please do not use the App.

The App

The App is a free dictation tool for macOS. No account or payment is required.

Using the App requires compatible hardware and a supported macOS version (currently macOS 26 or later on an Apple Intelligence-capable Mac). System requirements may change without notice.

License

Subject to your compliance with these Terms, the Developer grants you a non-exclusive, non-transferable license, free of charge, to install and use the App on Macs you own or control, for personal or business purposes.

All copyrights and other intellectual property rights in the App remain with the Developer or their rightful owners.

Restrictions

When using the App, you must not:

Redistribute, sell, rent, or sublicense the App
Modify, reverse engineer, decompile, or disassemble the App, except to the extent permitted by applicable law
Use the App for purposes that violate applicable laws or public order
Use the App to infringe the rights of others

Your content

You own all rights to the text you dictate and generate with the App. Because all processing happens on-device, the Developer never accesses your content and claims no rights to it.

AI output

Transcription and AI refinement may produce recognition errors or unintended changes. The accuracy and completeness of the output are not guaranteed. Always review important content before relying on it.

Updates and changes to the service

The App includes an automatic update mechanism (the Sparkle framework) that checks for updates on launch.

The Developer may change the App or the Site, or suspend or discontinue them, at any time. The Developer is not liable for any damages arising from such changes.

No warranty

The App and the Site are provided “as is”, without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose, and non-infringement.

Limitation of liability

To the maximum extent permitted by law, the Developer shall not be liable for any damages arising from your use of, or inability to use, the App or the Site, including loss of data, loss of profits, or business interruption.

Where applicable law does not allow the above limitation, the Developer’s liability shall be limited to the minimum extent permitted by that law.

Changes to these Terms

The Developer may revise these Terms as needed. Revised Terms take effect when posted on this page. Continued use of the App after changes constitutes acceptance of the revised Terms.

Governing law and jurisdiction

These Terms are governed by and construed in accordance with the laws of Japan. The Tokyo District Court shall have exclusive jurisdiction in the first instance over any disputes arising in connection with these Terms or the App.
