Terms of Use

What G4R is

G4R provides maintenance organization tools and Amazon search links. Replacement intervals and reminders are informational suggestions, not mechanical advice. Search links are not fitment guarantees — you are responsible for confirming product compatibility with your specific vehicle before purchase.

Product availability, pricing, reviews, and order handling are controlled by Amazon or the relevant seller. Amazon does not sponsor, endorse, or operate G4R or 4DAT LLC. As an Amazon Associate, 4DAT LLC earns from qualifying purchases.

Subscriptions

G4R Premium is an auto-renewable subscription billed to your Apple Account. The price and period are shown in the app before purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period; manage or cancel in iOS Settings > your name > Subscriptions. Use of the app is also governed by Apple's standard Licensed Application End User License Agreement.

Liability

The app and website are provided "as is" without warranties of any kind. To the maximum extent permitted by law, 4DAT LLC is not liable for damages arising from use of the app, the website, linked products, or maintenance performed on your vehicle. Follow your vehicle manufacturer's guidance and consult a qualified mechanic when in doubt.
