Privacy built around real diagnostics.

1. Overview

DashUI OBD-II (“DashUI,” “we,” “our,” or “us”) respects your privacy. This Privacy Policy explains how we collect, use, store, and protect information when you visit our website, use our app, connect an OBD-II adapter, use diagnostic features, or access premium features.

By using DashUI, dashuiobd.com, or related services, you acknowledge that information may be collected and processed as described in this Privacy Policy.

2. Information We Collect

Information You Provide

We may collect information that you choose to provide, including:

• Name, username, or contact information, if provided.
• Email address or other contact details when you contact support.
• Feedback, bug reports, feature requests, questions, or messages you send us.
• Account, license, or premium feature information, if applicable.

Vehicle and Diagnostic Data

When you use DashUI with an OBD-II adapter, the app may collect, process, display, or store vehicle-related diagnostic data, including:

• Diagnostic trouble codes, also known as DTCs.
• Live vehicle sensor data and OBD-II parameter IDs, also known as PIDs.
• Freeze-frame data, if supported by the vehicle.
• Adapter type, adapter behavior, connection status, and compatibility information.
• Vehicle protocol information.
• ECU responses and diagnostic communication logs.
• App performance data related to diagnostics and adapter communication.

This information helps us improve diagnostic accuracy, adapter compatibility, app performance, and reliability across different vehicles and adapters.

Premium Drive Tracking and Datalog Features

If you enable premium features, DashUI may collect or process additional vehicle-use data, such as:

• Trip and drive session history.
• Speed, RPM, throttle position, fuel economy, temperature, and related vehicle values.
• Timestamps and datalog entries.
• Driving behavior data, such as acceleration, braking, or usage patterns.
• Exported or saved vehicle datalogs.
• Location or route-related data only when a feature requiring location is enabled and permission is granted.

Device, App, and Website Data

We may collect technical information such as:

• Device model, operating system version, and app version.
• IP address, browser type, and website usage information.
• Crash reports, performance logs, and diagnostic error logs.
• Cookies or similar website technologies.

3. How We Use Information

We use information to:

• Provide app and website functionality.
• Read, display, and manage OBD-II diagnostic data.
• Improve diagnostic accuracy and reliability.
• Improve adapter compatibility.
• Enable premium drive tracking and datalog features.
• Save, export, or manage user-requested datalogs.
• Troubleshoot bugs, crashes, adapter issues, and vehicle communication problems.
• Respond to support requests.
• Improve app performance and user experience.
• Detect abuse, fraud, security issues, or misuse of the service.
• Develop new features and improve existing features.
• Comply with legal obligations.

We may also use aggregated or de-identified information to understand compatibility trends, common adapter issues, diagnostic reliability, and general app performance.

4. Premium Features and User Choice

Certain features may require additional data collection to function properly. For example, drive habit tracking, trip history, and vehicle datalogging may require storing or analyzing vehicle-use data over time.

Where required, these features depend on your settings, permissions, subscription status, or explicit use of the feature. You may be able to disable certain tracking, logging, or premium features from within the app settings.

5. How We Share Information

We do not sell your personal information. We may share information only in limited situations described below.

Service Providers

We may use trusted third-party service providers to help operate DashUI, including hosting, analytics, crash reporting, payment or subscription processing, customer support, email tools, and cloud storage if cloud features are offered.

App Stores and Payment Providers

If you purchase premium features, payment information may be processed by the applicable app store or payment provider. We do not directly receive or store full payment card details unless explicitly stated otherwise.

Legal Compliance, Safety, and Security

We may disclose information if required by law, legal process, court order, governmental request, or when necessary to protect our users, services, rights, property, or security.

Business Transfers

If DashUI is involved in a merger, acquisition, sale, restructuring, or transfer of assets, user information may be transferred as part of that transaction.

Aggregated or De-Identified Data

We may share aggregated or de-identified information that cannot reasonably identify you, such as general adapter compatibility statistics or diagnostic reliability trends.

6. Data Retention

We keep information only as long as reasonably necessary for the purposes described in this Privacy Policy, including providing the app and website, supporting diagnostics and premium features, improving compatibility and reliability, resolving support issues, meeting legal obligations, and maintaining security.

Diagnostic logs, crash reports, and support-related records may be retained for troubleshooting and product improvement. User-created datalogs may remain stored until deleted by the user, removed through app settings, or deleted by request where applicable.

7. Data Security

We use reasonable administrative, technical, and organizational safeguards to protect information against unauthorized access, loss, misuse, alteration, or disclosure.

However, no app, website, wireless adapter connection, or internet transmission is completely secure. You are responsible for using trusted adapters, keeping your device secure, and avoiding sharing exported datalogs with unintended parties.

8. Vehicle Data Notice

DashUI is designed to help users view and understand vehicle diagnostic information. Vehicle data can vary depending on the vehicle, adapter, ECU behavior, manufacturer implementation, permissions, and connection quality.

DashUI does not guarantee that all diagnostic information will be complete, accurate, available, or suitable for every vehicle. Diagnostic information should be used responsibly and should not replace professional mechanical inspection, repair advice, or safety judgment.

9. Cookies and Website Analytics

Our website may use cookies, analytics tools, or similar technologies to understand site traffic, improve performance, remember preferences, and maintain security.

You can usually control cookies through your browser settings. Disabling cookies may affect some website functionality.
