Privacy Policy – Mulsok 한국어

Effective Date: May 3, 2026  |  Last Updated: May 3, 2026

Browniebase ("we" or "operator") values the privacy of users of Mulsok ("the App"). Mulsok is usable anonymously without sign-up and collects only minimal information. We comply with applicable data protection laws including the EU GDPR and Korea's Personal Information Protection Act.

1. Information We Collect

• Anonymous Device Identifier – A random UUID auto-generated by Supabase on first launch. Does not identify individuals and is unrelated to advertising IDs.
• Location (Optional) – Precise location (lat/lon) collected only when "Find nearby spots" is used. Not stored on servers; immediately discarded after use.
• User Preferences – Display language, preferred activity (snorkel/scuba, etc.), favorite spots list.
• Map Viewport Coordinates – Sent to Mapbox for map tile loading (no user identifiers).
• Aggregate Usage Statistics – Daily active use (DAU), screen views, Klook CTA clicks (de-identified, aggregated).

We do NOT collect: name, email, phone number, credit card, government ID, or any other personally identifiable information.

2. Purpose of Collection and Use

• Provide underwater visibility grades (A~E) and ocean weather forecasts
• Recommend nearby dive spots based on location (only when permission granted)
• Maintain user preferences such as favorites, language, activity
• Analyze usage statistics for quality improvement
• Provide value-added service via external tour booking platform (Klook)

3. Data Retention

Anonymous device identifiers are discarded upon app deletion or user request. Location information is used in-memory and immediately discarded — never stored on servers. User preferences persist until changed by the user.

4. Third-Party Services

We do not sell or share user information for marketing purposes. The following third-party services are used to operate the App:

• Supabase Inc. – Database and anonymous authentication (servers in Singapore/USA, Privacy Policy)
• Mapbox – Map tile delivery. Viewport coordinates are sent to Mapbox for tile loading (no user identifiers). (Mapbox Privacy Policy)
• Open-Meteo / ECMWF / NOAA – Marine and weather forecast data sources. No user data is sent; only grid coordinates (lat/lon) are used.
• Klook Travel Technology Limited – Dive and snorkel tour booking platform. When a user taps a "Book" button in the App, they are redirected to the Klook website, where Klook's privacy policy applies. Mulsok does not directly share user data with Klook. (Klook Privacy Policy)

5. Location Data Handling

When the user invokes "Find nearby spots," precise location is collected once. It is used only to sort dive spots by distance, is never stored on servers, and is discarded from device memory immediately after use. Location permission can be revoked at any time via system settings; all forecast features remain fully functional without it.

6. Camera and Photo Handling

The App may request camera/gallery access for future review features. In the current version, camera and photos are not actively used. We will update this policy when such features become active.

7. External Payment and Affiliate Links

Mulsok provides links to an external tour booking platform (Klook). When a user completes a booking via these links, the operator may receive commission. This does not impose any additional cost on the user, and Klook's payment and refund policies apply. No payments occur within the Mulsok app itself.

8. Advertising

Mulsok currently does not display advertisements. We will update this policy with prior notice if ads are added in the future.

9. Security Measures

• All network communications are encrypted via HTTPS (TLS)
• Anonymous authentication tokens are stored in secure device storage
• Location data is used in-memory only and immediately discarded (never stored on servers)

10. User Rights

You may exercise the following rights at any time:

• Revoke location permission via system settings
• Delete all anonymous data by uninstalling the app
• Request deletion of specific data (contact via email)

Anonymous user IDs and preferences stored on Supabase servers are deleted upon user request or after a period of inactivity.

11. Children's Privacy

The App is not intended for children under 14 years of age. Diving, snorkeling, and similar activities should be performed by qualified adults or with adult supervision for safety reasons.
