Privacy Policy
Effective October 27, 2026
Talk, previously called DataMoum Talk, is operated by KCREW. This policy covers the mobile app and this support website. The device voice and LevelPlay update described below is being prepared for release. Older installed versions may still use Pangle directly and display the previous personalization setting.
Talk는 계정 없이 영어 표현을 학습하고, 기기의 영어 음성으로 듣고, 소리 내어 연습하는 앱입니다. 학습 기록과 설정은 기기에 저장합니다. 마이크를 사용하거나 사용자의 음성을 녹음·채점하지 않습니다. 보너스 학습을 위한 보상광고는 선택 사항이며, 새 버전은 맞춤 광고를 사용하지 않습니다. 광고 시작 전 KCREW 서버가 접속 IP의 국가를 확인하고, EEA·영국·스위스 및 국가를 확인할 수 없는 경우 광고를 제공하지 않습니다. 광고 제공업체는 광고 전달·측정·부정행위 방지를 위해 기기 식별자, IP 기반 대략적 위치, 광고 활동 및 진단 정보를 처리할 수 있습니다. 문의: admin@kcrew.co.kr.
1. Learning and local app data
No account is required. Learning progress, completed phrases, bonus-unlock expiry, age confirmation, app language and practice preferences are stored on your device. Talk does not upload your learning history or completed-phrase list to KCREW or provide those records to advertising networks. Local data remains until you clear app storage or uninstall the app.
2. Device speech playback
The updated app uses the operating system's built-in speech service to read the displayed English phrases. Talk does not request microphone access, record your voice, perform speech recognition or assign pronunciation scores. It does not send speech requests or recordings to a KCREW speech server. Voice availability, speech-engine processing and any voice downloads depend on your operating system, installed voice engine and device settings. The operating system or voice-engine provider's privacy terms apply to its service.
3. Optional rewarded advertising
Core lessons and review do not require watching a rewarded ad. If an eligible ad is available, you may choose to watch it to unlock bonus sets for 24 hours. The new app uses Unity LevelPlay mediation, including ironSource Ads/ISX, Unity Ads, Pangle, BIGO Ads and Mintegral, and LevelPlay Ad Quality. Including a network adapter does not mean that the network is enabled or that an ad will be served.
The new app always requests non-personalized advertising, sets GDPR consent to false and applies CCPA sale/sharing opt-out signals. It does not offer a personalized-ad opt-in or request Apple's tracking authorization. Saved personalization choices from previous versions cannot enable personalization in the new version. These restrictions do not eliminate all advertising data processing.
4. IP-based advertising eligibility
Before starting an advertising SDK, loading or showing an ad, Talk checks an eligibility result issued by KCREW's MASKLINGS privacy-scope service over HTTPS. The server uses the connection IP address to determine the country and returns a short-lived result. Device language, SIM information and a country chosen by the user are not used to decide advertising eligibility.
Advertising is held in the EEA, United Kingdom, Switzerland, and whenever the country cannot be verified or the check fails. Eligibility is kept only in memory, for no more than five minutes, and invalidated when the app backgrounds. Core learning remains available. Normal hosting and security logs may contain IP addresses and timestamps; the region check is used to apply advertising restrictions, not to create a learning profile.
5. Advertising data and sharing
When advertising is permitted and an enabled provider's SDK starts, the provider may process device and app identifiers, IP-derived approximate location, advertising interactions, impression and reward events, diagnostics, and performance information. Providers use this information for ad delivery, measurement, fraud prevention and related functionality under their own policies. LevelPlay Ad Quality may process information about advertising creatives and their display.
KCREW does not sell your learning history, completed phrases or voice recordings; Talk does not collect voice recordings. The app does not integrate Google Mobile Ads/AdMob, UMP, AppLovin MAX or Kakao AdFit. A reseller entry in app-ads.txt authorizes a seller relationship; it does not indicate that the app includes that seller's SDK.
6. Choices, retention and deletion
You can use core lessons without requesting rewarded ads, change operating-system advertising and voice settings, clear app storage or uninstall Talk. Advertising providers determine retention of information they process under their policies. App data stored locally is removed through the operating system's app-storage controls; operating-system backups, if enabled, follow your device and backup-provider settings. Contact us for privacy questions or requests.
7. Children and international processing
Talk is not directed to children under 13 and asks for an age confirmation before its main features. Hosting services, operating-system providers and enabled advertising providers may process information in other countries under their applicable policies and safeguards.
