DAT Ex Pro Privacy Policy

Effective date: April 8, 2026

This Privacy Policy explains how the DAT Ex Pro browser extension ("DAT Ex Pro", "extension", "we", "our", or "us") handles information when you use the extension.

1. Information We Process

DAT Ex Pro may process the following categories of data to provide core functionality:

• Authentication data
  • Your secret key (entered by you in the extension popup).
  • A locally generated device identifier used for secure backend verification.
• Cookie/session data
  • Browser cookies used to open and restore DAT sessions.
  • Domain/session metadata needed to save, retrieve, export, and merge session data.
• Proxy configuration data
  • Proxy host, port, username, password, and enabled status retrieved from the backend endpoint (/proxy/config) after authentication.
• Operational/technical data
  • Extension ID, client type headers, challenge-token request metadata, and basic request error logs.

2. How We Use Information

We use processed information only for extension functionality, including:

• Authenticating users and validating account/device access.
• Fetching, saving, and applying session cookies.
• Opening DAT sessions and restoring browsing state for supported domains.
• Enabling and syncing backend-managed proxy settings.
• Supporting optional export/import and administrative troubleshooting features.

We do not use your data for unrelated advertising profiling inside the extension.

3. Where Data Is Stored

In your browser (local extension storage)

The extension stores limited local values such as:

• isAuthenticated
• secretKey
• deviceId
• proxy_config_v2

This local storage is used to keep you logged in and run features like proxy sync and session management.

On backend services

The extension communicates with backend APIs (as configured in code) to:

• Validate access and device registration.
• Fetch/save cookie/session data.
• Fetch proxy configuration.

4. Proxy Use

When enabled by backend policy, DAT Ex Pro may configure browser proxy settings and provide proxy authentication credentials for proxy challenges.

• Proxy settings are applied only to support extension functionality.
• Proxy credentials are retrieved from the backend after successful authenticated requests.
• Proxy configuration can be cleared when authentication is removed or invalidated.

5. Data Sharing

We may share data only with:

• Our backend service providers required to operate authentication, session, and proxy services.
• Legal/regulatory authorities when required by law.

We do not sell personal information.

6. Data Retention

• Local extension data remains until you log out, clear extension storage, uninstall, or data is removed by extension logic.
• Backend-stored data retention is determined by operational and legal requirements.

7. Security

We use challenge-token verification and device-binding checks in backend workflows to reduce unauthorized access risk. However, no transmission or storage method is guaranteed to be 100% secure.

8. Your Choices

You can:

• Stop using the extension at any time.
• Remove extension local data by logging out or uninstalling the extension.
• Contact support to request account or stored data actions where applicable.

9. Children’s Privacy

DAT Ex Pro is not intended for children under 13 (or equivalent minimum age in your jurisdiction), and we do not knowingly collect data from children.

10. Changes to This Policy

We may update this Privacy Policy from time to time. The latest version should be published with an updated effective date.
