Privacy Policy
Last updated: 2026-10-26
This policy explains what EV Engine Sim (made by SENGTHAI SRENG, Cambodia) collects, why, and what you can ask us to do with it.
1. The car app
The car app reads your car's speed, pedal, gear and brake to play the sound. It sends us the technical information listed in section 3 of the Terms of Use (car model, head unit, settings, connection details, error logs, a coded form of your VIN for the licence). It does not send your name, contacts or location history.
2. The web app
In the browser, the web app reads your phone's GPS speed only to drive the sound. Your speed and position stay on your device and are not sent to us, unless you choose to send a drive report for support.
3. Purchases
When you buy, we keep your order: the edition, the price, the date, your licence code and the car it is tied to. KHQR payments go through your bank and our Telegram bot; we see the payment receipt you send. Card and wallet payments on the website are handled by our payment partner (Dodo Payments, the merchant of record); we never see or store your card details.
4. Accounts and contact
When accounts open on the website, we keep your email address and a protected form of your password, and the device you are signed in on. When you write to us by email, Telegram or WeChat, we keep the conversation to help you.
5. Cookies
The website uses only the cookies it needs: your language and, later, your sign-in session. Bot protection (Cloudflare Turnstile) may check your browser to stop automated abuse. We do not use advertising cookies or sell your data.
6. Who we share with
Only the services that run EV Engine Sim: Cloudflare (hosting and storage), our payment partners, and Telegram for KHQR orders. We share data with authorities only when the law requires it.
7. Keeping and deleting
We keep order and licence records as long as your licence is active and as the law requires for sales records. You can ask us to see, correct or delete your data at any time - contact us and we answer within 30 days.
8. Changes
We may update this policy; the date above shows the last change. If the English and Khmer text differ, the English text applies.
