Privacy Policy

1. Scope

This Privacy Policy explains how DHHPI handles information when you use the iPhone app and related website pages. It applies to product features such as market boards, charts, watchlists, alerts, rankings, calculators, ETF flow views, and support contact channels.

2. Data Categories

Depending on your usage, we may process the following categories of information:

• Account-free usage data: feature access events, app version, and device model used for performance diagnostics.
• User-configured market preferences: watchlist entries, symbol ordering, pinned items, and alert thresholds.
• Notification-related metadata: push token status and delivery logs required to send alerts you request.
• Technical telemetry: crash traces, latency indicators, and error codes used to improve stability.
• Support communications: email content and troubleshooting details you voluntarily provide.

3. How We Use Information

Information is used to operate and improve DHHPI, including:

• Rendering market views and preserving your watchlist and alert settings.
• Delivering in-app notifications and alert messages.
• Investigating crashes, fixing bugs, and optimizing app responsiveness.
• Responding to support requests and product feedback.
• Protecting service integrity and preventing misuse.

4. Market Data and Third-Party Sources

DHHPI displays market prices, ETF flow metrics, and related content from third-party providers. Provider-side delay, missing fields, or temporary feed interruptions may occur. Source references are listed in-app under Settings > Data Sources.

Third-party providers process data under their own privacy terms. We recommend reviewing those policies when relevant.

5. Data Retention

We retain information only as long as needed for the purposes described in this policy, including legal, security, and operational requirements. Retention periods may vary by data type, such as diagnostic logs, support records, and notification logs.

6. Security Measures

Reasonable administrative and technical safeguards are applied to reduce unauthorized access, alteration, disclosure, or loss risks. No online system can guarantee absolute security, but we continuously improve controls based on risk and operational needs.

7. International Processing

Your information may be processed in jurisdictions where service providers operate. When this occurs, we use appropriate safeguards to maintain a consistent level of privacy protection.

8. Your Choices and Rights

Depending on your location, you may have rights to request access, correction, deletion, or restriction of certain personal information. You can also manage alert permissions through your iPhone settings and stop support-related communication at any time.

9. Children

DHHPI is not directed to children under 13. If you believe a child provided personal information without guardian consent, contact us so we can review and take appropriate action.

10. Policy Updates

We may update this policy to reflect legal, technical, or product changes. Material updates will be reflected by revising the \"Last updated\" date on this page.
