Privacy Policy

Last updated: February 18, 2026

1. Introduction

HiAuto ("we", "our", "us") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, and safeguard information when you use the HiAuto mobile application and website (collectively, the "Service").

2. Information We Collect

2.1 Account Information

When you create an account, we collect your email address and the platform you use (iOS or Android). This is the minimum information required to provide the Service.

2.2 Vehicle Information

You may enter information about your vehicles, including make, model, year, and mileage. Vehicle data is stored separately from account data on isolated servers. We never link a vehicle to its owner on our servers.

2.3 Trip Data

We do NOT collect, transmit, or store your routes, locations, or GPS coordinates. The only trip-related information we record is the distance traveled. We have no knowledge of where you drove — only how far.

2.4 Device-Only Data

The association between your account and your vehicles exists only on your device. This data is never sent to our servers. Even we cannot determine which cars belong to which user.

3. How We Use Information

We use the information we collect to:

• Provide mileage tracking and generate trip distance logs
• Send smart maintenance reminders based on mileage and time intervals
• Generate tax-deduction-ready mileage reports
• Power the AI car assistant with your vehicle's specifications
• Improve the Service and develop new features

4. Data Sharing

We do not sell, rent, or share your personal information with third parties for marketing purposes. We may share data only in the following circumstances:

• Service providers: Trusted partners who help us operate the Service (e.g., cloud hosting), bound by strict data protection agreements
• Legal requirements: When required by law, court order, or governmental regulation
• Safety: To protect the rights, safety, or property of HiAuto, our users, or the public

5. Data Security

We implement industry-standard security measures to protect your data, including:

• Encryption of data in transit (TLS/SSL) and at rest
• Architectural separation of account data and vehicle data on isolated servers
• No storage of route or location data on our servers
• Regular security audits and updates

6. Data Retention

We retain your account information for as long as your account is active. Trip distance data is retained to provide mileage logs and reports. You may request deletion of your data at any time by contacting us.

7. Your Rights

You have the right to:

• Access the personal data we hold about you
• Request correction of inaccurate data
• Request deletion of your data
• Export your data in a portable format
• Withdraw consent at any time

8. Children's Privacy

The Service is not intended for children under the age of 16. We do not knowingly collect personal information from children under 16.

9. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of any material changes by posting the new policy on this page and updating the "Last updated" date.
