Terms of Service

Revving: Engine Simulator · Effective November 5, 2026

These terms are an agreement between you and Sensorial Systems (“Sensorial”, “we”, “us”) for playing Revving: Engine Simulator (“Revving”), our engine simulator game for Android, iPhone and iPad, and desktop computers. By installing or playing Revving, you agree to them. Revving collects no personal information; how it handles information is described in our Privacy Notice.

Your licence to play

We give you a personal, non-exclusive, non-transferable and revocable licence to install Revving and play it on devices you own or control, as these terms and your store’s rules allow. You may not:

• sell, rent, share or redistribute Revving or its engines, sounds or art;
• copy, modify or reverse engineer it, except where the law allows it;
• get around the purchase, or unlock engines you have not bought.

You are welcome to record and share videos and screenshots of yourself playing Revving, including on channels that earn money.

Engines and the purchase

• Two engines are free. The other seventeen are unlocked together by one purchase, made through the store you installed Revving from (Google Play, the App Store or Steam). Its price is shown by the store before you buy.
• The store takes the payment, and its own terms govern the payment and any refund. Ask the store for a refund; we cannot issue one ourselves, but write to us if you have a problem and we will help.
• The unlock belongs to your store account, so it returns on any of your devices signed in to that account, with Restore purchases. It cannot be transferred to another account or exchanged for money, and an unlock bought in one store does not carry over to another.
• If you are under the age of majority where you live, ask a parent or guardian before buying. Stores offer parental controls for purchases.

Your store’s terms

The terms of the store you got Revving from also apply to it: for Google Play, the Google Play Terms of Service; for the App Store, Apple’s Licensed Application End User License Agreement; and for Steam, the Steam Subscriber Agreement. If you got Revving from the App Store, Apple’s agreement is your licence for it, and these terms add to it; where they conflict, it applies. The store is not responsible for Revving or for supporting it; we are.

Updates and support

We may update Revving to fix problems and to add, change or improve engines and features. Your purchase unlocks every engine it described, and we will not take away engines you have paid for. Some updates may be needed to keep playing, and Revving may stop working on old devices or systems that the store or the game no longer supports. For help, see Support.

Playing safely

• Revving simulates engines for entertainment. Its sounds and behaviour are not an accurate guide to any real engine or vehicle, and should not be relied on for engineering, repair or driving.
• Engines are loud. Keep the volume at a comfortable level, especially with headphones, and take breaks.
• Don’t play while driving, or anywhere it would distract you from what is around you.

Our work and others’

Revving — its software, sounds, art and name — belongs to us or to those who license it to us, and these terms do not give you any right to use our names or logos. Revving’s engine simulation is ported from Engine Simulator by Ange Yaghi, under the MIT licence. Product names, logos and brands of real engines and vehicles are the property of their respective owners; Revving is not affiliated with or endorsed by any of the manufacturers it names. If you send us feedback or ideas, we may use them without owing you anything.

Warranties and liability

We work hard to make Revving good, but we provide it “as is”. To the extent the law allows, we make no promises beyond those in these terms: not that it will be free of errors or run on every device, nor that it will fit a particular purpose.

To the extent the law allows, we are not liable for indirect, incidental, special or consequential losses, or for lost profits or data; and our total liability for any claim about Revving is limited to the price of Revving’s unlock in your store.

Nothing in these terms limits any liability that the law does not allow us to limit, or takes away the rights you have as a consumer under the law of the country where you live.

Ending these terms

You can stop playing and uninstall Revving at any time. We may end your licence if you seriously break these terms, for example by getting around the purchase. The sections on our work, warranties and liability, and law and disputes continue after these terms end.

Changes to these terms

We may update these terms as Revving changes, and will change the date above when we do. If a change is significant, we will make it clear on this page. If you keep playing after a change takes effect, the new terms apply; if you don’t agree with them, stop playing and uninstall Revving.

Law and disputes

These terms are governed by the laws of Brazil. If a dispute comes up, write to us first: most problems are solved that way. If it cannot be solved, the courts of Brazil will decide it. If you are a consumer, you may bring a claim in the courts where you live — in Brazil, under the Consumer Defense Code, those of your own city — and the mandatory consumer laws of the country where you live continue to protect you.

If any part of these terms is found unenforceable, the rest still applies. If we don’t enforce a part of them straight away, we have not given up the right to do so later.
