Privacy Policy

Last Updated: 2026-04-28

Version 3.0.0

1. Overview

This Privacy Policy explains how the Dopamine Barrier app (the "App") handles personal data.

The App collects limited service usage data to analyze product usage and improve the service, and it also requests device permissions needed for its core blocking functionality.

2. Information Collected

The App does not generally collect directly identifying information such as your name, email address, or phone number during ordinary app use.

However, the following categories of data may be collected or processed.

2.1 Analytics Data

We use Firebase Analytics to measure app usage and funnel conversion. This may include event data such as app opens, onboarding completion, barrier group creation, barrier activation, barrier success, paywall views, trial starts, and subscription purchases.

General technical information about the device and app environment may also be processed through Firebase and related infrastructure, such as app instance identifiers, device and OS information, app version, language, and approximate region.

We use this information only for product analytics, feature improvement, funnel optimization, troubleshooting, and service operations.

2.2 Device Permissions and On-Device Information

To provide its core functionality, the App may request the following device permissions:

• (iOS) Screen Time Restriction Permission: Required to block specific apps.

This permission is used solely for the app-blocking feature, and users may revoke it at any time.

• (Android) Accessibility permissions: Required to block specific apps.

This permission is used solely for the app-blocking feature, and users may revoke the Accessibility permissions at any time.

3. Data Protection

We use collected analytics information only within the scope of operating and improving the service.

We do not sell personal information, and we do not request App Tracking Transparency (ATT) permission for cross-app or advertising tracking purposes.

However, third-party service providers such as Firebase Analytics may process information as necessary to provide their services.

4. Use of Third-Party Services

The App may use the following third-party services:

• Firebase Analytics (Google): app analytics, conversion measurement, and product improvement
• Apple App Store / Google Play Store: subscription billing and purchase restoration

These third-party providers may process information in accordance with their own privacy policies.

5. Children's Privacy (COPPA Compliance)

The App is intended for users who are at least 13 years of age. We comply with the Children's Online Privacy Protection Act (COPPA).

We do not knowingly collect personal information from children under 13 years of age.

If we become aware that a user is under 13 years of age, we will promptly terminate their access to the Service.

Parents and guardians should monitor their children's use of mobile applications. If you believe we may have any information from or about a child under 13, please contact us at echo.kindness.business@gmail.com.

6. California Privacy Rights (CCPA)

If you are a California resident, you have specific rights under the California Consumer Privacy Act (CCPA).

6.1 Information We Collect

As stated in this Privacy Policy, the Service may collect limited data for app analytics, but we do not sell personal information or engage in third-party advertising tracking.

6.2 Your CCPA Rights

California residents have the right to:

• Right to Know: Request information about the categories and specific pieces of personal information we have collected
• Right to Delete: Request deletion of personal information we have collected
• Right to Opt-Out: Opt-out of the sale of personal information
• Right to Non-Discrimination: Not be discriminated against for exercising these rights

We do not sell personal information to third parties. Where applicable law grants you privacy rights, we will review and respond to requests within the scope required by law.

6.3 Do Not Sell My Personal Information

We do not sell, rent, or share personal information with third parties for their direct marketing purposes.

7. International Users and Data Transfers

Because we use third-party services such as Firebase Analytics, your data may be processed on servers located outside your country of residence.

We consider reasonable safeguards where appropriate, but actual processing practices may also depend on the policies of the relevant third-party providers.

8. User Rights & Contact Information
