요즘말 사전 (Yojeummal Dictionary) Privacy Policy
Last Updated: July 24, 2026
Effective Date: Upon app release
1. Overview
요즘말 사전 ("the App") takes your privacy seriously. This Privacy Policy explains what information we collect and how we use it. The App does not require an account and does not collect your name, email, or phone number. Dictionary searches, favorites, and study history stay on your device.
2. Information We Collect
2.1 Sentence Decode Feature
When you use "Sentence Decode" (translating a sentence containing Korean slang), the text you enter is sent to our server (slang.hedvion.com) for processing. The server does not store the original text — it is discarded immediately after processing. Only a daily usage count per device is recorded, used to enforce the free daily limit (with extra uses available via rewarded ads).
2.2 Device Identifier (device_id)
On install, the App generates a random unique identifier (device_id, UUID) stored on your device and sent with server requests. This value cannot be linked to your name, phone number, or email and does not identify you personally. It is used only to track daily usage limits (sentence decode, quiz, etc.) and resets on reinstall.
2.3 Automatically Collected Information (Advertising)
The App includes third-party advertising SDKs (AppLovin MAX and its mediated networks, including Google AdMob and Meta Audience Network) that may collect the following when ads are shown to free users:
| Information | Source | Purpose | Legal Basis |
|---|---|---|---|
| Advertising ID | Device Settings | Ad targeting, performance measurement | User Consent |
| Device Information | Device | Ad compatibility | Service Delivery |
| Approximate Location | Device Settings | Location-based ads | User Consent |
| App Usage Logs (ad impressions/clicks) | App Events | Ad performance analysis | Service Delivery |
AppLovin Privacy: https://www.applovin.com/privacy/ · Google AdMob Privacy: https://policies.google.com/privacy
2.4 User-Generated Information (Local Storage Only)
The following stays only on your device and is never sent to a server: your word list (favorited slang), recent searches, quiz history and study stats, and app settings.
2.5 Local/Push Notifications
"Slang of the day" and (Pro only) "new slang alerts / weekly report" notifications do not collect personal data. Notifications can be disabled anytime in app settings.
2.6 Information We Do Not Collect
We never collect account information, precise GPS location, camera/microphone/contacts/photo library access, or payment card details (handled directly by Apple/Google).
3. Purposes of Use
| Purpose | Details |
|---|---|
| Dictionary search & sentence decode | Core app functionality |
| Daily usage limit management | device_id-based counting and rewarded-ad credits |
| Advertising | Displaying ads to free users and measuring performance |
| In-app purchase | Processing and verifying the Pro (non-consumable) purchase |
4. Information Sharing & Third Parties
4.1 AppLovin MAX and Mediated Ad Networks
Shares advertising ID, device information, approximate location, and ad interaction logs for personalized advertising and measurement. You can reset your Advertising ID or disable personalized ads in device settings.
4.2 Apple App Store / Google Play (Payment)
Purchase history (amount, date) is shared for verification. Card details are processed directly by Apple/Google, never by our servers.
4.3 Other Third Parties
We do not share personal information with any other third party except under court order, legal requirement, investigation of Terms violations, or fraud/security prevention.
5. Data Retention
| Information | Retention | Deletion |
|---|---|---|
| Sentence decode input text | Discarded immediately after processing | N/A |
| device_id daily usage count | Rolling 24-48 hours | Auto-expires |
| Advertising ID | Until reset | Device settings |
| Word list / search history / settings | Until app deletion | Uninstall app |
6. Your Rights
You can view and delete your local data directly in the App, and uninstalling deletes all local data. You may disable personalized ads via iOS Settings > Privacy > Apple Advertising, or Android Settings > Google > Ads.
7. Security
Sentence decode requests and payment verification use HTTPS/TLS encryption. Local data (word list, settings) is protected by the device app sandbox.
8. Children
요즘말 사전 is primarily used by parents seeking to understand their children's slang; the App does not collect names, ages, or emails, so no child personal data is generated.
9. International Data Transfer
Data is stored locally by default. Advertising (AppLovin MAX and mediated networks) may process data on servers worldwide per their respective policies.
10. Policy Changes
This Privacy Policy may be updated; major changes will be announced via app notice or update notes.
