LumiCut ("the App") is a video editing application for Apple platforms (macOS, iOS, and iPadOS). Your privacy is fundamental to how we build the App. This policy explains what data we access, how we use it, and what we don't do.
LumiCut does NOT use any third-party AI services, cloud AI, or external servers. All AI and machine learning features, including subtitle generation (WhisperKit/CoreML), video analysis (Apple Vision), audio classification (Apple SoundAnalysis), and text-to-speech (Piper TTS/ONNX Runtime), run entirely on your device using bundled models. No video, audio, images, text, or analysis results are ever sent to any server or third party. The app works fully offline with no internet connection required for any AI feature.
The App does not track you. We do not use advertising identifiers, fingerprinting, or any other tracking technology. Our Apple privacy manifest declares NSPrivacyTracking = false with no tracking domains.
We do not collect, transmit, or store any personal data. Our Apple privacy manifest declares an empty NSPrivacyCollectedDataTypes array. There are no analytics, crash reporting, or telemetry services in the App.
All video editing, compositing, and AI-powered features run entirely on your device. The app does NOT use any third-party AI service, cloud-based AI, or external machine learning API. No user data, including video, audio, images, or text, is ever sent to any external server. The app works fully offline; no internet connection is required for any AI feature.
Every AI/ML model used by the app is bundled within the app binary and executes locally on the device's CPU, GPU, or Neural Engine:
VNDetectFaceRectanglesRequest, VNDetectHumanBodyPoseRequest), running on-device as part of iOS/macOS.The AI Video Coach feature analyzes your videos to provide quality scores and recommendations. All analysis is performed entirely on your device using Apple's built-in system frameworks. No third-party AI service is used, and no video, audio, or analysis results are sent to any server.
The specific on-device frameworks and techniques used:
Vision framework (VNDetectFaceRectanglesRequest, VNRecognizeTextRequest, VNImageRequestHandler) for face detection, text recognition, brightness, sharpness, and stability. All processing runs on the device's Neural Engine/GPU.SoundAnalysis framework (SNClassifySoundRequest) and AVAudioEngine for speech classification, voice energy, speaking pace, filler words, and audio balance. Speech transcription uses WhisperKit (on-device CoreML). No audio leaves the device.NaturalLanguage framework and bundled scoring algorithms to evaluate hook, pacing, call-to-action, and outro quality.Scores and recommendations are generated by automated on-device algorithms. They are stored locally on your device (in UserDefaults/cache) and are never transmitted externally.
Subtitle generation uses WhisperKit, an open-source on-device speech recognition library built on Apple's CoreML framework. All model files are bundled within the app. No download or internet connection is required. All transcription is performed locally on your device's Neural Engine and GPU. No audio data is sent to any server.
On iOS, for non-English languages, the App may use Apple's on-device SFSpeechRecognizer with requiresOnDeviceRecognition enabled, ensuring all transcription remains on your device.
The App stores your preferences (such as export settings, onboarding state, and AI Coach report history) in UserDefaults. This data stays on your device and is never transmitted.
The App accesses video and image files only when you explicitly select them via the system file picker. The App does not access files in the background or scan your file system.
The App may request microphone access for voiceover recording. Microphone audio is processed locally and is never transmitted to any server.
Subscriptions are handled entirely by Apple through the App Store. The App never receives, processes, or stores any payment information, credit card numbers, or billing details.
The App does not include any third-party analytics, advertising, crash reporting, or cloud AI SDKs. The App does NOT use any third-party AI service (such as OpenAI, Google AI, or any cloud-based ML API). The App does not make any network requests to process user data. The only third-party open-source libraries used are:
Both libraries execute entirely on-device with no network component. All remaining AI features use Apple's built-in system frameworks (Vision, SoundAnalysis, NaturalLanguage, CoreML), which are part of iOS/macOS and run entirely on-device.
We do not knowingly collect any data from anyone, including children under 13. Since the App collects no data, it is compliant with COPPA by design.
If we update this policy, we will post the revised version on this page with a new effective date. Since we collect no data, any future changes would be minimal.
