Calypso IDE

Terms of Service

Last updated: 3 June 2026

These Terms of Service (“Terms”) govern your use of the Calypso IDE app (“Calypso”, “the app”). By installing or using Calypso, you agree to these Terms. If you do not agree, do not use the app.

License to use the app

Calypso grants you a personal, non-exclusive, non-transferable, revocable license to install and use the app on devices you own or control, for the purpose of writing, running, and managing your own code.

Your responsibilities

  • Your code and data are yours. You are responsible for the code you write and run, and for the consequences of running it. Calypso executes code at your direction.
  • Back up your work. Calypso stores your projects on your device. You are responsible for backing up anything important — for example by pushing to a Git remote. We are not responsible for data loss.
  • Lawful use. You agree not to use Calypso to create, run, or distribute anything unlawful, or in any way that violates the terms of the third-party services you connect to.
  • Credentials. You are responsible for keeping your Git and service credentials secure.

Third-party services and software

Calypso interoperates with independent third-party services and software, including (where you choose to use them) the Termux app, package registries (such as esm.sh, PyPI, and the npm registry), CDNs (such as jsDelivr), and Git hosts (such as GitHub). These are operated by others under their own terms and privacy policies. Calypso is not affiliated with, and is not responsible for, those services or software. Your use of them is governed by their respective terms.

No warranty

Calypso is provided “as is” and “as available”, without warranties of any kind, whether express or implied, including but not limited to warranties of merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the app will be uninterrupted, error-free, or that it will run any particular code correctly.

Limitation of liability

To the maximum extent permitted by law, we will not be liable for any indirect, incidental, special, consequential, or punitive damages, or for any loss of data, profits, or goodwill, arising out of or related to your use of (or inability to use) Calypso — even if advised of the possibility of such damages.

Changes to these Terms

We may update these Terms as the app evolves. Material changes will be reflected here with an updated “Last updated” date. Continued use of the app after changes take effect constitutes acceptance of the revised Terms.
