Service Providers

We may share your information with third-party service providers who perform services on our behalf, such as:

  • OAuth authentication providers (Google, Apple)
  • Analytics and crash reporting services

Legal Requirements

We may disclose your information if required to do so by law or in response to valid requests by public authorities.

4. OAuth Authentication
OAuth 2.0
Car Brain uses OAuth 2.0 for secure authentication through Google and Apple Sign-In.

How It Works

When you sign in with Google or Apple:

  • You're redirected to the provider's secure login page
  • We receive only basic profile information (name, email, profile picture)
  • We never see or store your password
  • You maintain full control over your account

Permissions We Request

  • Basic profile information (name and email)
  • Profile picture (optional)
  • Email address for account management

Revoking Access

You can revoke Car Brain's access to your OAuth account at any time through:

  • Google Account Settings → Security → Third-party apps with account access
  • Apple ID Settings → Password & Security → Apps Using Your Apple ID
5. Data Security
We implement appropriate technical and organizational security measures to protect your personal information.
  • End-to-end encryption for data transmission
  • Secure OAuth 2.0 authentication
  • Regular security audits and updates
  • Encrypted storage of sensitive data
  • Access controls and authentication requirements

While we strive to protect your personal information, no security system is impenetrable. We cannot guarantee the absolute security of our databases.

  • Access: Request a copy of your personal data
