Terms of Service

Effective Date: April 27, 2026 | Last Updated: May 24, 2026

Please read these Terms of Service ("Terms") carefully before using the Anbu mobile application ("Service"). By installing or using the Service, you agree to be bound by these Terms. If you do not agree, please do not use the Service.

1. About the Service

Anbu is a daily wellness check application that helps families quietly monitor the well-being of aging parents and loved ones living alone. The Service operates by sending automatic daily wellness signals ("heartbeats") from the monitored person's device to connected family members.

2. Definitions

1. "Service" means the Anbu mobile application and all related features provided by us.
2. "Subject" means a user who is registered as the person being checked on, whose device sends daily heartbeat signals.
3. "Guardian" means a user who is connected to a subject and receives wellness status updates and alert notifications.
4. "Heartbeat" means the daily wellness signal automatically transmitted from a subject's device.
5. "Invite Code" means the unique code issued to a subject, used to establish a connection with a guardian.
6. "Emergency Help Request" means the function by which the Subject directly taps the [🚨] emergency help button within the app to immediately notify all connected Guardians that assistance is needed.

3. Account Registration

1. Your agreement with us begins when you install the app and select your role (subject or guardian) to complete registration.
2. Registration is device-based. We do not require a username, email address, phone number, or any personal information to create an account.
3. By registering, you consent to the automatic collection of device information as described in our Privacy Policy.

4. Service Description

4.1 Subject Features (Free)

• Automatic daily heartbeat transmission at a scheduled time
• Manual wellness report ("I'm okay") button
• Invite code generation and sharing to connect with guardians
• Emergency help request feature: tap the [🚨] button to immediately alert all connected guardians (when the user grants location permission, the current location is delivered one time to guardians; if permission is denied, only the alert is delivered without location data)

4.2 Guardian Features (Subscription)

• Connect with subjects using their invite code
• Real-time wellness status monitoring
• Step-by-step alert notifications (Caution → Warning → Urgent)
• Battery status and device condition alerts
• Receive subjects' emergency help requests (when location data is included, the location can be viewed on a map)
• Notification settings and Do Not Disturb configuration
• Monitor up to 5 subjects with a single subscription

5. Subscription and Payment

1. The subject app is completely free. No payment is ever required for subjects.
2. Guardian features include a 3-month free trial starting from first registration.
3. After the free trial, an annual auto-renewing subscription (billed once per year) is required to continue receiving alert notifications. The exact price, currency, and applicable taxes are displayed at the time of purchase in the Apple App Store or Google Play Store.
4. Payments are processed through the Apple App Store or Google Play Store. Payment method details (card numbers, bank account information, billing addresses, etc.) are handled exclusively by Apple's and Google's payment systems. Our servers do not store payment method details — we retain only the receipt validation token for the purpose of verifying subscription status.
5. Auto-Renewal: Subscriptions automatically renew for the same subscription period (1 year) unless canceled at least 24 hours before the end of the current period. Your payment method registered with the store will be charged automatically at the time of renewal.
6. Price Changes: If the subscription price changes due to our policies or store policies, the new price applies from the next renewal. The Apple App Store requires advance notification and your explicit consent for price increases; if you do not consent, your subscription will be automatically canceled. The Google Play Store applies a similar price change notification policy.
7. You can cancel your subscription at any time through your device's subscription management settings. Deleting the app alone does not cancel your subscription.
8. Free Trial Conversion: If you do not cancel before the free trial ends, your subscription will automatically convert to a paid subscription and your registered payment method will be charged.
9. We handle your personal data in accordance with our Privacy Policy.

5.1 Subscription Expiry

• When your subscription expires, you can still access the dashboard and view subject status.
• However, alert notifications will not be sent until the subscription is renewed.
• Subject heartbeat transmission continues regardless of guardian subscription status.

6. User Responsibilities

1. You agree to use the Service only for its intended purpose of wellness monitoring.
2. You must not:
   • Use another person's device credentials without authorization
   • Interfere with the normal operation of the Service
   • Use the Service for unauthorized commercial purposes
   • Violate any applicable laws or regulations while using the Service

7. Our Responsibilities

1. We will make reasonable efforts to provide the Service continuously and reliably.
2. We will protect your data in accordance with our Privacy Policy.

2. We will provide advance notice of planned interruptions when possible.

9. Important Disclaimers

10. Account Deletion

1. You can delete your account at any time through the "Delete Account" option in the app settings.
2. Upon deletion, all your data (device information, heartbeat logs, connection records, subscription information, etc.) is immediately and permanently deleted and cannot be recovered.
3. If a subject deletes their account, all connected guardians will be notified.
4. Deleting your account during an active subscription does not entitle you to a refund. Refund policies are governed by the applicable app store (Apple/Google).

11. Limitation of Liability

1. THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EITHER EXPRESS OR IMPLIED.
2. We are not liable for service interruptions caused by force majeure events, telecommunications provider outages, or circumstances beyond our reasonable control.
3. We are not liable for service issues caused by user actions (device malfunction, battery depletion, app deletion, denied permissions, etc.).
4. To the maximum extent permitted by applicable law, our total liability for any claims arising from or related to the Service shall not exceed the amount you paid for the Service in the 12 months preceding the claim.

12. Governing Law

1. If a dispute arises between you and us regarding the Service, both parties will first attempt to resolve it through good-faith negotiation.
2. These Terms shall be governed by and construed in accordance with the laws of the Republic of Korea, without regard to its conflict of law provisions.
3. Any legal proceedings shall be brought in the competent courts of the Republic of Korea.
