Privacy Policy

Lensmera  |  Effective date: July 10, 2026

1. Information We Process

The developer holds no user database. Personal data processing connected with the App is limited to:

• Advertising in the free version — Google AdMob (see Section 3)
• In-app purchase processing — Apple App Store / Google Play (see Section 4)

Photos, videos and practice records you create are stored on your device (and, where you choose, in your device's photo library).

2. Device Permissions

You can change any permission at any time in your device settings. The App keeps working with whatever you decline, minus that one feature.

2-1. Face Data (Processed On Your Device Only)

Some Lensmera features need to find a face in the picture in order to work: the composition coach that suggests how to frame a portrait, the ID-photo auto-fit that crops and sizes a photo to an official standard, and the optional Reshape slider in the photo editor. These features use the face detection built into your device's operating system (Apple Vision on iOS, Google ML Kit on Android) and run entirely on your device.

What is processed: where a face is in the frame, how large it is, how far it is turned, and — for ID-photo auto-fit and Reshape only — a few landmark points such as the eye centers and the jawline that are needed to calculate a crop or an image adjustment. Lensmera does not recognize or identify anyone. It does not create a faceprint, face template, face embedding or any other biometric identifier, and it cannot tell one person from another.

Storage and retention: none. This face geometry exists only in your device's memory while the feature is running — for a single camera frame, or for a single edit you make — and is discarded immediately afterwards. It is never written to a file, a database or a server, and it does not survive closing the App. Because nothing is retained, there is nothing to delete; deleting a photo, or the App, removes everything that remains.

Sharing: never. Face data is not shared with the developer, with advertising partners, or with any other third party, and it is never transmitted off your device. The App has no server of its own and no image-upload feature — the photos and videos you take stay on your device.
얼굴 데이터(생체 정보)는 기기 안에서만 처리됩니다. 구도 코치·증명사진 자동 맞춤·얼굴 리쉐이프 기능은 운영체제에 내장된 얼굴 감지(iOS Apple Vision·Android Google ML Kit)로 사진 속 얼굴의 위치·크기·회전, 그리고 증명사진·리쉐이프에 한해 눈 중심·턱선 등 소수의 기준점만 사용합니다. 앱은 사람을 인식·식별하지 않으며 얼굴 특징 템플릿 등 어떠한 생체 식별 정보도 생성하지 않습니다. 이 정보는 기능이 동작하는 순간의 메모리에만 존재하고 즉시 폐기되며, 파일·데이터베이스·서버에 저장되지 않고 제3자에게 제공되거나 기기 밖으로 전송되지 않습니다. 저장되는 것이 없으므로 별도 파기 절차가 없으며, 사진이나 앱을 삭제하면 남는 것도 사라집니다.

3. Advertising (Free Version)

The free version shows ads served by Google AdMob. AdMob may process a limited set of data on Google's side to serve and measure ads, such as the advertising identifier of your device, coarse ad-related signals and crash/performance diagnostics of the ad SDK. This is the only third-party data processing in the App.

• Ads in the App are served as non-personalized ads. The App does not request App Tracking Transparency (ATT).
• On Android, you can reset or delete your advertising ID and opt out of ads personalization in system settings.
• See Google's Privacy Policy and AdMob data practices.
• Purchasing Lensmera Premium (Lifetime) removes ads.

International transfer of personal data (개인정보 국외 이전)

Because AdMob is operated by Google, serving ads in the free version involves a transfer of limited data outside the Republic of Korea. In accordance with Article 28-8 of the Korean Personal Information Protection Act, we disclose:

그 밖에 인앱 결제 처리를 위한 Apple/Google로의 정보 이전은 각 스토어의 개인정보처리방침에 따르며, 개발자는 결제 정보를 보관하지 않습니다.

4. In-App Purchase Data

The optional Premium purchase is processed entirely by Apple App Store or Google Play. We never see or store your payment details. The App only receives a purchase confirmation (receipt/entitlement) from the store to unlock Premium on your device.

5. Children's Privacy

Lensmera is rated 4+ (iOS) / Everyone (Android). The App does not knowingly collect personal information from children. For related inquiries, please contact us.

6. Data Retention & Deletion

Because your photos, videos and practice records stay on your device, you can delete them at any time inside the App or by deleting the App. We retain nothing on servers — there is nothing for us to delete.

Face data used by the on-device features described in Section 2-1 is never stored at all, so there is nothing to retain or delete.

7. Third-Party Services

7-1. Optional AI Model Downloads

Some larger AI tools (such as the Magic Eraser, Lens blur, Cutout, Colorize, and automatic video captions) require a one-time, opt-in download of an AI model file to your device. On Android the file is delivered by Google Play; on iOS it is fetched from model-hosting mirrors (for example, Hugging Face or GitHub). As with any internet download, the hosting server receives standard connection metadata (such as your IP address) to deliver the file. Nothing is uploaded: your photos, videos and audio are never sent anywhere, and the AI tools run on your device once the model is installed. Each model file can be deleted at any time in the App's settings.
일부 대용량 AI 도구(예: 매직지우개·아웃포커스·누끼·컬러화·동영상 자동 자막)는 AI 모델 파일을 기기로 1회 옵트인 다운로드해야 합니다. Android에서는 Google Play가, iOS에서는 모델 호스팅 미러(예: Hugging Face·GitHub)가 파일을 전달하며, 여느 인터넷 다운로드와 마찬가지로 호스팅 서버는 파일 전달을 위한 표준 연결 정보(IP 주소 등)를 수신합니다. 올려 보내는 것은 없습니다 — 사진·영상·음성은 어디로도 전송되지 않으며, 모델 설치 후 AI 도구는 기기 안에서 동작합니다. 각 모델 파일은 앱 설정에서 언제든 삭제할 수 있습니다.

8. Your Rights

Depending on your jurisdiction (including the Korean Personal Information Protection Act and the EU GDPR), you may have rights to access, correct, delete, or port personal data, and to object to or restrict processing. Since we hold no personal data on servers, most rights are exercised directly on your device (delete the data or the App). For anything else — including questions about advertising data held by Google — contact us and we will help, or exercise choices in your device's ad settings.

9. Changes to This Policy

We may update this policy from time to time. The latest version is always available on this page.
