Effective date: November 6, 2026

Article 1 (Purpose)

These Terms govern the relationship between the user ("User") and the developer ("Company") regarding the use of the "heyUp" application (the "Service"), defining rights, obligations, liabilities, and procedures related to the processing of personal information.

Article 2 (Service Introduction)

• "heyUp" is a lock screen customization application that allows users to utilize various functional features directly on their lock screen in a stylish layout.
• All services and contents are provided free of charge and contain third-party advertisements.

Article 3 (Privacy Policy)

1. Collection of Personal Information and Permissions

• The Service does not require traditional user registration or sign-ups, and does not directly collect or store personally identifiable information (such as names, emails, or phone numbers) on remote servers.
• However, to facilitate the "Mini Home contact search and registration" feature within the app, the Service requests and utilizes the **Contact (Address Book) Permission** on the device, subject to user consent.

2. Data Usage and Security

• The phone's address book is read only briefly, to show you the list while you pick a contact, and is not stored.
• The name of a contact you add to Mini Home yourself is stored only on your device so the feature can work, and it is removed when you delete it from Mini Home or uninstall the app.
• Contact information is never transmitted to any external server.

3. Third-Party Sharing and Provision

• To sustain free operations, the Service integrates third-party advertising libraries. Ads are delivered through AppLovin, together with ad networks connected via AppLovin such as Pangle, Meta, Liftoff and InMobi. Depending on the app version, Kakao AdFit may also be included.
• During this process, these third-party ad networks may collect and share the user's **Device or Other IDs (e.g., Google Advertising ID)** for ad delivery, analytics, and fraud prevention.
• The Service also uses Google Firebase Analytics to understand how the app is used. App usage records and device information may be sent to Google in this process; no information that identifies you personally, such as your name or contacts, is included.
• Aside from this, no sensitive personal information, including the user's contacts, is ever shared with or provided to third parties.

4. Cookies and Tracking Technologies

The Service does not use proprietary cookies or independent user tracking technologies. The advertising and analytics tools described in Article 3.3, however, operate under each provider's own policy.

5. User Rights and Data Deletion

• Users can revoke or adjust system permissions (such as Contacts) at any time through their smartphone's system settings.
• Since the Service does not remotely store user personal information on servers, no separate deletion procedure (such as account deletion) is required. What you set up and write in the app is stored only on your device and is removed when you uninstall the app.
• The advertising identifiers described in Article 3.3 are handled under each ad provider's own policy. You can reset your device's advertising ID or opt out of personalized ads at any time in your Android settings.
• If you nevertheless wish to request data deletion or have any privacy-related inquiries, please contact us at sonjoon82@gmail.com and we will respond within 7 business days.

6. Data Retention Period

App data is stored only on your device and not on any server operated by this Service, so there is no separate retention period on our side. Retention of the advertising identifiers and analytics information described in Article 3.3 follows each provider's own policy.
