Terms of Use
Last updated: 2026-10-26
These terms cover the EV Engine Sim car app, the web app and this website. They are the same terms every driver accepts in the car app.
1. Your safety comes first
You are always fully responsible for driving safely and for obeying traffic laws. Do not look at, set up or adjust the app while driving - only when the car is parked. The engine sound is for entertainment only: it is not a safety, warning or driving-assistance feature, and it may be wrong, late or silent.
2. Keep the volume sensible
Keep the sound at a level where you can always hear sirens, horns, your car's own warnings and the people and traffic around you. Follow any local rules about vehicle noise.
3. Car data and what is shared
To follow your driving, the app reads data from your car, such as speed, pedal, gear and brake, with your permission. It only reads; it never controls or changes your car. When you verify your car or send a report - and by itself, without asking, when the car does not connect fully or when a car not yet on our list connects - the app sends the developer technical information: car make and model, head unit details, app settings, connection details and app error logs. It does not send your name, contacts or location history. To tie a PRO licence to this car, the app sends a coded form of your car's VIN (or of the head unit's id) and the VIN's last 6 characters, and checks the licence each time it is online. The app also sends, with a random number in place of your identity: the app version, the car you chose, the head unit and Android version, your country, how each setup step went, which speaker outputs work, and which Store packs you preview, download or delete. This information is used only to support your car and improve the app. By accepting, you agree to this sharing.
4. No warranty
The app is provided "as is" and "as available", without any warranty of any kind. The developer does not promise that it works with your car, is free of errors, or will always be available or updated.
5. Limitation of liability
To the fullest extent the law allows, the developer is not liable for any accident, injury, damage to any vehicle or property, fine, loss of data, or any direct or indirect loss that comes from using or not being able to use the app. You use the app at your own risk.
6. Your car and its warranty
Installing apps on your car's system may not be approved by your car's maker or dealer. You are responsible for checking that this is allowed for your car and for any effect on its warranty or service.
7. Names and trademarks
Car and brand names and pictures in the app are used only to describe sound styles and supported cars. The app is not made, approved or sponsored by any car maker, and all trademarks belong to their owners.
8. No reverse engineering or content extraction
EV Engine Sim, its software, licence verification mechanisms, sound profiles, audio files and assets are the proprietary intellectual property of SENGTHAI SRENG. You agree not to decompile, disassemble, reverse engineer, unpack, modify, circumvent licence or PRO / MAX checks, or extract, copy, redistribute or publicly share any sound files or software components from the app or its servers.
9. Changes
These terms may change with an app update. If they change in an important way, the app will ask you to accept them again. If there is any difference between the English and Khmer text, the English text applies.
