End User License Agreement

Effective October 23, 2026. This End User License Agreement (“EULA”) is between you and Composite Code LLC (“we”, “us”) and covers the Substratal Hub apps: the web app (PWA) at dashboard.substratalapps.com, and the apps for macOS, Windows, Linux, iOS/iPadOS and Android (each an “App”).

1. License

Subject to this EULA and the Terms of Service, we grant you a personal, non-exclusive, non-transferable, revocable license to install and use the Apps on devices you own or control, to access Substratal. The Apps are licensed, not sold.

2. Restrictions

You may not, except as allowed by law or by an open-source license that applies to a component:

  • copy, modify, or create derivative works of the Apps;
  • reverse engineer, decompile, or disassemble them;
  • rent, lease, sell, sublicense, or redistribute them;
  • remove proprietary notices; or
  • use them to violate the Acceptable Use Policy.

3. Accounts, data and privacy

The Apps need a Substratal account. What they collect and how it’s used is described in the Privacy Policy. Signing in on a device stores a session credential in that platform’s secure storage (Keychain, Credential Manager, the Secret Service, Android Keystore, or an HttpOnly cookie on the web). Notifications are optional, and you can turn them off in the App or your device’s settings.

4. Updates

We may release updates that fix issues, add or remove features, or keep the App compatible with the Substratal API. Some updates may be required to keep using the App; an App built for an API version that has been retired will ask you to update.

5. Open-source components

The Apps include open-source software, licensed under its own terms, listed in each App’s About screen or source repository. Where the source code of an App is published under an open-source license, that license governs your use of the source code.

6. App store terms

If you got an App from an app store, that store’s terms also apply. For Apps from Apple’s App Store:

  • This EULA is between you and Composite Code, not Apple. Apple isn’t responsible for the App or its content.
  • Your license is limited to use on Apple-branded products you own or control, as permitted by the App Store’s Usage Rules.
  • Apple has no obligation to provide maintenance or support for the App.
  • If the App fails to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price, if any. To the maximum extent permitted by law, Apple has no other warranty obligation for the App.
  • Apple isn’t responsible for addressing any claims by you or a third party relating to the App, including product liability, legal or regulatory non-compliance, or consumer-protection claims.
  • If a third party claims the App infringes its intellectual property, Apple isn’t responsible for the investigation, defense, settlement, or discharge of that claim.
  • You confirm you aren’t located in a country subject to a US Government embargo or designated as “terrorist supporting,” and aren’t on any US Government list of prohibited or restricted parties.
  • Apple and its subsidiaries are third-party beneficiaries of this EULA and may enforce it against you.

Google Play, the Microsoft Store, Flathub, and other stores’ terms apply in the same way to Apps distributed through them.

7. Termination

This license ends automatically if you breach this EULA or your account is terminated. When it ends, stop using and delete the Apps.

8. Disclaimers, liability and law

The disclaimers, limitation of liability, and governing law (Washington State, USA) in the Terms of Service apply to the Apps.
