1. Purpose of the App

OnSun is operated by Vireo Energy Pty Ltd (“we”, “our”, or “us”). The App provides solar forecasting and appliance scheduling tools to help users align energy use with solar generation. The App is for informational and educational purposes only and should not be relied upon for operational, financial, or safety-critical decisions.

2. Eligibility and account scope

The App is intended for users aged 13 and over. If you subscribe to a paid plan, you must be legally able to enter a binding contract in your jurisdiction (e.g. be of age of majority). By using the App, you represent that you meet these requirements.

3. Licence to use the App

We grant you a personal, non-exclusive, non-transferable licence to use the App for your own personal, non-commercial purposes. You may not resell, redistribute, or sublicense the App or its content. You may not reverse engineer, decompile, or disassemble the App except to the extent that applicable law expressly permits it.

4. Acceptable use

You must not misuse the App or our services. This includes: abusing or overloading the forecast or proxy services; using automated scraping, bots, or scripts to extract data; interfering with the App, our systems, or other users; or attempting to bypass rate limits, security measures, or access controls. We may suspend or block access in response to such conduct.

5. Forecast accuracy and limitations

We use third-party weather and solar data sources and our own algorithms to generate forecasts. Because solar generation depends on many uncontrollable factors—such as weather, shading, and system performance—we cannot guarantee that any forecast or suggestion will reflect actual solar output or energy savings.

You acknowledge that forecasts are estimates only, and real-world results may differ. We are not liable for any losses, damages, or missed savings resulting from reliance on forecasts or recommendations.

6. Third-party services

Forecast data (e.g. Open-Meteo), reverse geocoding, hosting, and app-store billing are provided by independent third parties. Their terms and policies apply when data or requests are sent to them. We are not responsible for their availability, accuracy, outages, changes, or errors. If a third-party service changes or becomes unavailable, we are not liable for any impact on the App.

7. Device, OS, and connectivity

App performance and features depend on your device, operating system version, permissions (e.g. location), and internet access. Features may not work correctly if you deny required permissions, are offline, or use unsupported or outdated software. We are not responsible for issues caused by your device or network configuration.

8. User responsibilities

You are responsible for ensuring your site details and appliance settings are accurate. The App may provide recommendations, but you make the final decisions about when and how to operate your appliances. The App does not directly control equipment unless explicitly stated for compatible devices.

Appliance consumption estimates (block profiles). The App uses simplified "block load profiles" to estimate when and how much power your appliances consume. A block profile is an approximation—a stepped representation of power draw over time—not a precise real-time measurement of your specific appliance. These profiles are built from typical usage patterns and publicly available manufacturer specifications, but they are estimates only. Your actual appliance may have variable load cycles, different power draws, or efficiency ratings that differ from the profile used. Consumption may be significantly over or under estimated depending on your specific appliance model, age, settings, load size, and operating conditions. We do not guarantee the accuracy of these estimates and recommend users verify consumption against their own utility data or smart metering where available.

9. Subscriptions and payments

The App offers free and paid subscription plans. Paid features may include extended forecast days, unlimited appliances, and advanced insights. Subscriptions are billed through the Apple App Store or Google Play.

  • Subscriptions auto-renew unless you cancel at least 24 hours before the end of the current period.
  • Your account is charged for renewal within 24 hours before the end of the current period.
  • You can manage and cancel subscriptions in your Apple ID or Google account settings. Cancellation stops future charges but does not refund the current period.
  • If you start a free trial, it will convert to a paid subscription at the end of the trial unless you cancel before then.
  • Subscription pricing may change; we will give notice via the platform where required. Feature availability may vary by region and platform.
  • No refunds are offered for partial subscription periods, except where required by law.

10. Data and privacy

Your privacy is important to us. The App collects minimal information, such as your chosen location and appliance details, to deliver its features. Please review our Privacy Policy for details.

11. Limitation of liability

Nothing in these Terms excludes, restricts, or modifies any consumer guarantees, rights, or remedies under the Australian Consumer Law (or equivalent in your jurisdiction) that cannot be excluded by law.

To the fullest extent permitted by law (and subject to the above):

  • The App and all information are provided “as is” without warranties of any kind.
  • We disclaim all implied warranties, including accuracy, reliability, or fitness for purpose.
  • We are not responsible for any loss of data, system damage, or financial loss arising from use of or reliance on the App.
  • Our total liability, if any, is limited to the amount paid (if any) for your subscription in the 12 months prior to the claim.

12. Indemnity

You agree to indemnify and hold harmless Vireo Energy Pty Ltd and its officers, directors, and employees from any claims, losses, or expenses (including reasonable legal costs) arising from your misuse of the App, unlawful use, or breach of these Terms.

13. Termination

We may suspend or terminate your access to the App or our services if you breach these Terms, including acceptable use. You may stop using the App at any time. Uninstalling the App removes locally stored data, subject to platform behaviour (e.g. iCloud or backup). We do not maintain user accounts; there is no separate “account” to delete beyond uninstalling.

14. Intellectual property

The App and its content (including design, text, software, and underlying intellectual property, excluding third-party data and materials) are owned by Adaptive Energy Group Pty Ltd or its licensors and are licensed to Vireo Energy Pty Ltd for operation and distribution.

Vireo Energy Pty Ltd operates and distributes the App under licence. Third-party trademarks, data, and content belong to their respective owners. You do not acquire any rights in our or third-party intellectual property by using the App.

15. Changes and availability

We may update, modify, or discontinue any part of the App at any time. Subscription pricing and plan features may change with notice where required (e.g. via the app store). These Terms may also be updated periodically; the effective date will be revised when they change. Continued use of the App after changes means you accept the updated Terms.

16. Governing law

These Terms are governed by the laws of Victoria, Australia. You agree to submit to the exclusive jurisdiction of the courts located in Victoria for any disputes related to these Terms.
