Terms of use

Updated: 2026-11-09

CarGenius helps you understand what is going on with your car, but it does not replace a mechanic. Use it with the car parked and check with a professional before any major repair.

What CarGenius is

CarGenius is an app that reads your car's data through an OBD2 adapter and uses artificial intelligence to explain what it may mean. It is provided by [full name or company name]. By using it you accept these terms.

The diagnosis is guidance

The AI can be wrong. Its answers rely on what the scanner could read, and a generic scanner can't see every system in the car. Each diagnosis states how confident the AI is. Treat it as guidance for going to the shop knowing what to ask, never as a guarantee that something is fine or broken. Costs shown are rough estimates.

Use the app carefully

  • Don't use your phone while driving. Check the data with the car stopped or ask a passenger to do it.
  • If a red warning light comes on, the engine overheats or the brakes or steering feel wrong, pull over somewhere safe and get help, whatever the app says.
  • Clearing fault codes turns the light off but doesn't fix the cause, and it may make you fail an emissions test until the car finishes its self-tests.

The adapter

The app works with the CarGenius adapter and with many ELM327 Bluetooth LE adapters from other brands, but we can't guarantee it works with every car or every adapter. Sale, shipping, warranty and return terms for the CarGenius adapter will be published when it goes on sale in your country.

What is not allowed

Don't use CarGenius for illegal purposes, to tamper with the car's emissions or safety systems, or to try to damage, copy or overload our service.

Liability

We do our best to make CarGenius work well, but we provide it as is. To the extent the law allows, we are not liable for damage to the car, repair costs or decisions made based on the app. This does not limit the rights consumer protection law gives you in your country.

Content and brand

The CarGenius name, logo, app and site texts are ours. Generic code definitions come from OBDex (CC0 license) and complaint and recall data from the US NHTSA.

Changes and governing law

We may update these terms; the date below shows the current version. They are governed by the laws of [country and state]. Questions: hola@cargenius.app.
