1. Introduction

Lumos (hereinafter referred to as "the App," "we," or "our") is a tool dedicated to helping family partners, especially women, visualize, fairly distribute, and collaboratively manage household responsibilities. We deeply understand the privacy of family matters and are committed to protecting your and your family's information to the highest standards. This Privacy Policy aims to transparently explain how we collect, use, store, and protect your information, as well as the rights you have.

• The family name and customized member nicknames/relationships (e.g., "Dad," "Mom") you provide when creating a family space.
• Personal or family information you actively fill in (non-mandatory), such as city or time zone (used for localized reminders).

Family Collaboration Content

2.2 Information Collected Automatically

Device and Log Information

To ensure stable operation of the App, we collect device model, operating system version, app version, network status, and error logs. This information is anonymized and used for troubleshooting and performance optimization.

Usage Data

We collect aggregated data such as feature usage frequency (e.g., which module is used most) and operation flows (e.g., average steps to create a task) to improve user experience. This data is not directly linked to your identity.

Notification Interaction Data

To ensure effective delivery of notifications, we track the delivery status (whether successfully delivered to the device), but we do not track whether you click on them.

2.3 Requested Permissions and Their Use

Notification Permission

Used to send you task reminders, meeting notifications, recurring schedule alerts, and care check-in reminders.

Calendar Permission (Optional)

If authorized, tasks and meetings can be written to your device's system calendar, utilizing its reminder functionality. We do not​ read, modify, or delete other events in your calendar.

Contacts Permission (Optional)

If authorized, when inviting family members, we can locally match and display contact names from your address book for easier selection. We do not​ upload or store your complete contact list. Invitation information (e.g., email or phone number) will be used solely for sending invitations.

Providing and Improving Core Services

4. Information Storage, Sharing, and Disclosure

4.1 Storage Location and Security

• Local Storage: All your data is primarily stored locally on your device, ensuring privacy and offline availability.
• Cloud Backup (Optional): When you log into an account and enable backup, your data is securely uploaded to our cloud servers located in [Please fill in: e.g., AWS Singapore Region]​ via end-to-end encryption to enable cross-device recovery. The encryption key is controlled by your device; we cannot decrypt the content of your data.
• Data Security: We employ industry-standard security measures such as transport encryption (TLS), encryption of data at rest, and strict access controls to prevent unauthorized access, use, or disclosure.

4.2 Data Sharing Principles

• Strictly Limited Sharing: We do not​ sell, rent, or trade your personal or family data to third parties for advertising or marketing purposes.
• Visible Only to Family Members: All household data, tasks, charters, and emotional records you create within the App are, by default, visible only to the family members you have invited and who have joined. Anonymous posts in the Community section are visible to other users.
• Service Providers: We only share the minimal information necessary to enable service functionality with strictly bound third-party service providers (e.g., cloud hosting services, error analytics tools). These providers are not permitted to use your data for any other purpose.
• Legal Requirements: We will only disclose your information when legally compelled to do so.

5. Your Rights and Controls

You have full control over your information:

• Access and Correction: You can view and edit most of the information you provide within the App at any time.
• Delete Data:
  • Partial Deletion: You can delete individual tasks, records, or posts within modules like "Collaborate" or "Home."
  • Complete Deletion: In "My" > "Privacy & Security" > "Clear All Data," you can permanently delete data stored locally on the device. To delete cloud backups, please contact us.
• Export Data: You can export your family data (in formats like JSON or CSV) for archiving in "My" > "Privacy & Security."
• Manage Permissions: You can turn off Lumos's notification, calendar, or contacts permissions anytime in your device's system settings. Turning off permissions only affects related features.

You can upgrade to a logged-in account at any time to enable these features.

7. Children's Privacy

Our service is not directed at children under the age of 13. Although the App may be used to manage household tasks involving children, we do not directly collect personal information from children. We encourage parents to guide their children regarding privacy settings for family digital tools.

Features like the "Mood Thermometer," care reminders, and related content in the community are designed as educational and assistive tools​ to promote mutual understanding and self-awareness among family members. If you or your family members are experiencing persistent emotional distress, psychological stress, or any health issues, you must seek help from qualified doctors, psychotherapists, or other professional healthcare providers.
