American V-Twin Diagnostics — Last updated: May 1, 2026

Introduction

American V-Twin Diagnostics ("we," "our," or "the App") is a mobile application designed to help motorcycle owners and mechanics diagnose fuel injection issues on American V-Twin motorcycles equipped with Delphi EFI systems. We are committed to protecting your privacy and being transparent about how we handle your information.

Information We Collect

The App collects the following information when you create an account:

• Name — Used to personalize your experience within the App.
• Email address — Used for account login, password recovery, and important account notifications.
• Phone number — Used as an alternative method for account recovery and verification.

The App also stores the following data locally on your device:

• Motorcycle profiles — Year, model, engine type, mileage, and nickname for up to 3 saved bikes.
• Diagnostic results — Records of completed diagnostic sessions including steps taken and outcomes.
• Service records — Maintenance intervals and service history you enter for your motorcycles.
• Notes — Any personal notes you attach to your motorcycle profiles.

How We Use Your Information

We use the information we collect to:

• Provide and maintain the App's diagnostic and reference features.
• Authenticate your identity and secure your account.
• Enable password and account recovery.
• Personalize your in-app experience (e.g., displaying your name and saved motorcycle profiles).

Data Storage and Security

Your motorcycle profiles, diagnostic results, service records, and notes are stored locally on your device using secure on-device storage. This data is not transmitted to external servers unless you explicitly choose to export or share it (e.g., generating a PDF report and sharing it via email or text).

Account credentials are stored securely using industry-standard encryption practices. We use secure authentication methods to protect your account from unauthorized access.

Data Sharing

We do not sell, trade, or rent your personal information to third parties. We do not share your data with advertisers. Your diagnostic data and motorcycle information remain private to you unless you explicitly choose to export and share reports.

Biometric Data

The App offers optional biometric authentication (Face ID or fingerprint) for convenient login. Biometric data is processed entirely by your device's operating system and is never accessed, stored, or transmitted by the App. We only receive a success or failure result from the device's biometric system.

Third-Party Services

The App does not currently integrate with third-party analytics, advertising, or tracking services. If this changes in the future, this privacy policy will be updated accordingly.

Children's Privacy

The App is not intended for use by children under the age of 13. We do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal information, please contact us so we can take appropriate action.

Your Rights

You have the right to:

• Access your personal data stored in the App.
• Update your account information (name, email, phone number) through the App's profile settings.
• Delete your account and all associated data by signing out and removing the App from your device.
• Export your diagnostic results as PDF reports for your own records.

Data Retention

Your locally stored data (motorcycle profiles, diagnostics, service records) persists on your device until you delete it or remove the App. Account information is retained as long as your account is active. If you wish to delete your account, you may do so through the App, which will remove all associated data.

Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be reflected on this page with an updated "Last updated" date. We encourage you to review this policy periodically for any changes. Continued use of the App after changes are posted constitutes acceptance of the revised policy.
