Refund Policy
Last updated: 2026-10-31
PRO ($4.99) and MAX ($13.99) are one-time digital purchases. We want them to work for you.
1. 7-day refund if it does not work
If, within 7 days of your purchase, EV Engine Sim cannot work in your car or on your phone, contact us. We will first try to fix it with you. If we cannot make it work, we refund the full price.
2. How to ask
Write to us by email, Telegram or WeChat (see Contact) within 7 days of the purchase, with your order number or licence code, your car make and model (or your phone), and what does not work. A short video or the car app's report helps us fix it quickly.
3. How the money comes back
Card and wallet payments are refunded to the same card or wallet through our payment partner. KHQR payments are refunded by bank transfer to the account that paid. Refunds are sent within 7 days of our decision; your bank may take a few more days to show it.
4. After a refund
The licence code of a refunded purchase is turned off, and the car and the web app go back to LITE.
5. Not covered
We do not refund after 7 days, when the app works as described but you changed your mind, or when a licence was shared or misused against the Terms of Use. This does not limit any rights you have under the law where you live.
6. Cancellation
PRO and MAX are one-time purchases, not subscriptions: nothing renews and there is nothing to cancel. An order you started but did not pay is never charged.
