Terms of use

1. Who these terms cover

These terms cover the iPhone apps published by MARVAR, currently EVSim and ClustR – Display for Tesla (“the apps”), and this website. The apps are published on the App Store by Valentin Varadi, a private individual and independent developer (“the developer”, “we”). Contact: hello@marvar.eu.

2. Apple’s standard license applies

The apps, including their in-app purchases and subscriptions, are licensed to you under Apple’s standard Licensed Application End User License Agreement (Apple’s standard EULA). We do not use a custom EULA. This page adds practical information about the apps and this website; it does not replace or change the license in Apple’s EULA. If anything here conflicts with Apple’s EULA, Apple’s EULA prevails.

3. Using the apps

Use the apps for your own personal purposes and follow the law. Do not copy, resell, reverse engineer or misuse them, and do not use them in a way that could harm other people or the service.

4. Safety (ClustR)

ClustR is a secondary display. Use a secure phone mount that does not block your view, airbags or controls, set up the app while parked, and follow your local laws. Your car’s own displays and warnings always take precedence over anything ClustR shows. ClustR is not a certified safety device.

5. Estimates (EVSim)

EVSim’s results are estimates based on your trips, vehicle profiles and current conditions. Real-world results will differ. Do not rely on them as a promise about range, charging time or cost.

6. Purchases and subscriptions

Some features are optional paid features, such as EVSim Unlimited and ClustR Pro. Payments are processed by Apple. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period, and you can manage or cancel them in your Apple Account settings. Prices, trials and availability are shown in the App Store. Refunds are handled by Apple under its own rules.

7. Third-party names

ClustR is independent and is not affiliated with, endorsed by or sponsored by Tesla, Inc. Tesla is a trademark of Tesla, Inc. Vehicle names and brands shown in EVSim belong to their respective owners and are used only to identify vehicles. Apple, the Apple logo and App Store are trademarks of Apple Inc.

8. Our rights

The apps, this website, and their design, text and code belong to their developer, except for third-party materials that belong to their owners. We may update or change the apps over time.

9. No warranty and limits on liability

The apps are provided “as is”. To the extent the law allows, we are not responsible for losses that come from using, or being unable to use, the apps. Nothing here limits rights you have under mandatory consumer law.

10. Privacy

How each app handles data is explained on its privacy page: EVSim and ClustR.

11. Changes to these terms

We may update these terms. The “Last updated” date at the top shows the latest version.
