This Privacy Policy applies to all mobile applications provided by MonoApps (hereinafter "Company").
1. Purpose of Collecting and Using Personal Information
The Company collects and uses personal information for the following purposes:
- Providing and operating app services
- Responding to customer inquiries
- Improving services and developing new features
- Providing personalized advertisements (for ad-supported free services)
2. Personal Information Collected
The Company collects only the minimum information necessary to provide services. Depending on the app's features, the following information may be collected:
- Camera: QR code/barcode scanning, photo capture, etc.
- Photo Library: Image selection and saving
- Microphone: Voice recognition and recording features
- Location: Location-based services
- Contacts: Contact-related features

※ Each app only requests necessary permissions. Most data is processed on the device only. However, for some apps, data may be transmitted to servers for service provision and quality improvement, in which case separate consent will be obtained within the app. Detailed permission information can be found on each app's store page.
- Customer Inquiries: Email address (for customer support purposes)
- Service Usage Identifier (x-device-id): Some apps transmit an anonymous device identifier to servers during API requests for usage limit enforcement, service stability analysis, and anonymous statistics. This identifier is reset when the app is uninstalled.
- Voice Recording Data (STT-enabled apps): For apps that include speech-to-text functionality, recorded audio may be transmitted to an external STT server for conversion processing, and is deleted immediately after processing.
- Purchase/Payment Information: For apps offering paid subscriptions or in-app purchases, receipt information (transaction ID, product ID, purchase date) is collected to manage purchase records. Payment method details such as credit card information are handled directly by the Apple App Store or Google Play Store payment system; the Company does not access this information.
3. Advertising and Third-Party Services
Our apps display advertisements through Google AdMob. The following information may be collected for advertising services:
- Advertising Identifier: IDFA for iOS or GAID for Android
- Device Information: Device model, operating system version
- App Usage Data: Ad impressions and click information
This information is processed in accordance with Google's Privacy Policy. For more details, please refer to Google's Privacy Policy.
Users can limit ad tracking or reset their advertising identifier in device settings.
Apps that offer paid services use RevenueCat to manage subscriptions and in-app purchases. The following information may be transmitted to RevenueCat:
- Receipt Data: Transaction ID, product ID, purchase and expiration dates
- Anonymous Identifier: Used for purchase restoration and cross-platform synchronization
- Platform Information: iOS or Android
RevenueCat does not process payment method information (such as credit card numbers); payments are processed exclusively through the Apple App Store or Google Play Store payment systems. For details, please refer to the RevenueCat Privacy Policy.
4. AI Services and Data Usage
Some of our apps provide AI-based features (e.g., plant disease diagnosis), and data provided by users may be used to improve service quality.
- Data Collected: Images captured or uploaded by users during service use (e.g., plant photos)
- Purpose of Use: Providing AI-based diagnostic services and training/improving AI models
- De-identification: Collected images are used only after removing personally identifiable information such as location data (EXIF).
- Separate Consent: Data usage for AI training purposes requires separate consent within the app, and users can withdraw consent at any time through app settings.
- Retention Period: Data is retained until the purpose of AI training is achieved and will no longer be used for training upon consent withdrawal. However, data already used for training may be technically difficult to individually separate and delete from the AI model.
5. Additional Processing for the Hogamdo App
The Hogamdo app provided by the Company offers a facial image analysis feature, and processes personal information as follows:
Face Data is Not Retained on Our Servers: The Hogamdo app does not retain any face data on our servers. Facial images and any facial features, embeddings, or other face-recognition data derived from them are deleted from server memory immediately upon completion of the analysis and are never written to any persistent storage on our servers, such as a database or file system.
- Data Collected: Facial images (for analysis only, not retained on the server); when applying for matching based on the analysis result, email address, nickname, year of birth, and gender.
- Purpose of Processing: Facial images are used as input to the country-specific likability analysis algorithm; matching information is used to deliver matching results via email.
- Server-Side Face Data Retention: Face data is not retained on our servers. Facial images and facial feature data are deleted from server memory immediately after analysis and are never persistently stored on our servers in any form.
- On-Device Local Storage (for User Convenience): Analyzed facial images and result scores are stored locally inside the app's private sandbox (Application Documents/history_images/), up to the 10 most recent entries. This data never leaves the device, is inaccessible to other apps, and is fully removed when the user taps "Clear History" in Settings or uninstalls the app.
- Matching Information Retention: Email, nickname, year of birth, and gender provided during matching application are destroyed immediately when the matching service ends or upon a withdrawal request.
- Third-Party Provision: Facial images and face data are not provided to any third party; analysis processing takes place only on the Company's own servers.
- Security Measures: Data in transit is protected by HTTPS (TLS 1.2+) encryption. Photos themselves are not stored on the server and are removed from memory immediately after analysis.
- User Rights: Data deletion requests can be sent to [email protected]. Matching application withdrawal can also be requested at the same email address.
6. Purpose of App Permissions
Our apps may request the following device permissions to provide services:
- Camera: QR code and barcode scanning functionality
- Photos/Storage: Loading images from gallery, saving QR code images
- Vibration: Haptic feedback upon scan completion
These permissions are only activated when using the relevant features, and users can revoke permissions at any time in device settings. Revoking permissions may limit the use of related features.

The Company takes the following security measures to protect users' personal information:
- Local Storage: User data such as scan history and generated QR codes are stored only on the device and are not transmitted to external servers.
- Encrypted Communication: SSL/TLS encryption is used when communicating with external services.
