Privacy Policy

Gratitude Jar values your personal information and complies with applicable laws and regulations, including the Personal Information Protection Act. The app is designed with on-device technology as its top priority to ensure that your valuable records are never leaked externally.

1. Purpose of Processing Personal Information

The app processes personal information for the following purposes. The information will not be used for any purposes other than those stated below. If the purpose of use changes, necessary measures such as obtaining separate consent will be taken.

• Recording and managing gratitude memos: To store and display the one-line gratitude memos entered by the user on the device.

2. Categories of Personal Information Processed

The app processes only the minimum information necessary to provide the service. Core data is not stored on any server.

• User-generated content (gratitude memos): Text data entered directly by the user. (This data is stored only in the local database on the user's device and is never transmitted to the developer or any external server.)
• Device information (optional): Anonymized statistical data for fixing app errors and improving the service (e.g., OS version, app version, device model name).

3. Retention Period of Personal Information

All gratitude memo data is retained solely on the user's device for as long as the app is installed. When the user deletes the app, all data stored on the device is immediately destroyed. No server-side backup exists, so recovery is not possible.

4. On-Device AI (Local LLM) Processing

The app's core feature — weekly/monthly reflection analysis — is performed by a local LLM built into the user's smartphone, not by an external cloud AI server. Therefore, the contents of your journal are never transmitted externally via the network, even during analysis.

5. Third-Party Provision and Entrustment of Personal Information

In principle, the app does not provide personal information to third parties or entrust processing to external parties. However, when anonymous statistical tools such as Firebase Crashlytics are used for app stability analysis, non-identifiable information may be processed.

6. Rights of Data Subjects and How to Exercise Them

Users may modify or delete their data at any time through the in-app settings. Users may also withdraw consent to the collection and use of personal information by deleting the app.

7. Measures to Ensure Security of Personal Information

In accordance with Article 29 of the Personal Information Protection Act, the app takes the following measures to ensure security:

• Data encryption: Ensuring the security of the local database on the device.
• Minimum access permissions: Requesting only the minimum device permissions necessary to provide the service.
