PiFl Labs Co., Ltd. ("Company", "we", "us") is committed to protecting your personal data. This Privacy Policy explains how information is handled when you use the mobile application Kkachi: Your Folk Painting (formerly Kkachi: Korean Saju; "App"). For matters not covered here, our general Privacy Policy applies.
In short: the App works without accounts, servers, ads or analytics. The birth details you enter are encrypted and processed on your device only and are never sent to us.
1. Purpose of Processing
The App does not collect personal data on our servers. What you enter is processed only on your device, for these purposes:
- Saju chart and readings: your birth date, time and place are used on the device to calculate your Four Pillars and show prewritten readings.
- Reading together (compatibility): details of another person, entered with their consent, are used to show a relationship reading.
- Widget and reminders: the home-screen widget and the optional morning reminder show the day's text.
- Support: replying to inquiries you send by email.
2. Information We Collect
We do not use accounts, advertising, analytics, device location or advertising identifiers.
| Category | Items | Handling |
|---|---|---|
| Your profile | Nickname, birth date (solar or lunar, leap month), birth time (optional), birthplace (country or city), traditional cycle convention, male or female (optional) | Entered by you. Stored only in the device's secure storage; never sent to us |
| People you read with | The same items, entered by you with that person's consent | As above |
| Settings | Language, text size, reduce motion, fortune display (weather or score), reminder on/off, calculation conventions | Stored on the device |
| Widget content | The daily text and fortune weather (or score) for each date; no birth details, name or birthplace | Written by the App to the device's widget storage |
| Inquiries | Email address and message | When you email us |
3. Retention Period
- Information on your device: until you choose "Delete all birth details" in Settings or uninstall the App (for iOS, see section 8). We cannot access it.
- Email inquiries: 3 years after the inquiry is resolved
4. Disclosure to Third Parties
We do not disclose personal data to third parties through the App. When you share a folk-art card through your device's share sheet, you choose the app and recipient, and the card contains no birth date, name or birthplace.
5. Processing Entrustment
Information you enter in the App is not entrusted to anyone. Email inquiries are handled as described in our general Privacy Policy. The App is distributed through the Apple App Store and Google Play; information those platforms handle under their own policies (such as downloads and crash reports you agree to share) is governed by their privacy policies.
6. Advertising Identifier and Tracking
The App shows no ads, collects no advertising identifier and does not track you, so it does not ask for App Tracking Transparency permission.
7. App Permissions
- Notifications (optional): requested only when you turn on the morning reminder. Reminders are scheduled on the device without any server.
- Boot completed and vibration (Android): used to restore scheduled reminders and the widget after a restart, and to vibrate for a reminder.
- Add to Photos (iOS, optional): used only when you choose "Save Image" on the share screen, to add the folk-art card to Photos. The App never reads your photos.
- The App does not use internet, location, contacts, photo reading, camera or microphone permissions.
8. Data Destruction
- On your device: "Delete all birth details" in Settings immediately removes your profile, saved people, widget text and scheduled reminders. On Android, uninstalling the App removes them too. On iOS, the encrypted birth details may remain in the system Keychain after uninstalling; no other app can read them, and the App deletes them the first time it runs after a reinstall. To remove them at once, use the menu above before uninstalling. App backups and device-to-device transfers do not move birth details to another device.
- Inquiries: permanently deleted in an unrecoverable way after the retention period.
9. Your Rights
You can view, edit and delete your information in the App at any time. Because App data never leaves your device, the only records we hold are email inquiries; requests about them can be sent to privacy (at) pifl-labs.com. Please get consent before entering another person's details.
10. Security Measures
- Birth details kept in the iOS Keychain (this device only) and Android encrypted storage
- Excluded from app backups and device-to-device transfers
- No birth details, name or birthplace in the widget, reminders or share card
- No network transfer features
11. Children's Privacy
The App is not directed at children under 14, and we collect no personal data through it. If an inquiry reveals personal data of a child under 14, we delete it promptly. Guardians may contact privacy (at) pifl-labs.com.
12. International Data Transfers
Information you enter in the App is not transferred abroad. For email inquiries, see our general Privacy Policy.

14. GDPR (European Economic Area)
If you are located in the EEA, you have additional rights under the General Data Protection Regulation, including the right to access, rectify, erase, restrict processing, data portability, and object to processing. Contact us at privacy (at) pifl-labs.com.
