Loomur Privacy Policy

1. Introduction Loomur ("the App", "we", "our") is a video subtitle editor that runs entirely on your device. This policy explains what information the App accesses and how it is handled. 2. Information the App Accesses Videos and Media When you import a video, the App reads that file solely to generate subtitles and compose the exported output. Your videos, audio, and subtitle content are not uploaded to our servers, shared with third parties by us, or transmitted outside your device by the App for processing. App Preferences The App stores one preference on your device — your selected transcription language — using Apple's UserDefaults. This data never leaves your device. Photo Library Access When you export a finished video, the App requests permission to save the exported result to your Photo Library. The App does not browse, upload, or analyze your Photo Library. If you import media through a system-provided picker, browsing and selection are handled by iOS. 3. On-Device Processing All audio analysis and subtitle generation is performed entirely on your device using WhisperKit, an open-source on-device speech recognition framework. Your audio, video, and generated subtitles are not sent to our servers for transcription or processing. 4. Network Requests The only network activity the App performs is a one-time download of the AI model file from Hugging Face when the model is first needed. This download is used only to obtain the model weights required for on-device transcription. During this download, the App does not upload your videos, audio, subtitles, project files, or app-created user content. The model download is handled as a standard network request to Hugging Face. 5. Data Storage All project files, including imported videos, subtitle data, thumbnails, and exported working files, are stored locally in the App's sandboxed Documents folder on your device. We do not have access to this data. Deleting the App removes locally stored App data, subject to standard iOS behavior and any files you may have separately exported or saved outside the App. 6. Third-Party SDKs The App uses the following open-source libraries: * WhisperKit (argmax-oss-swift): On-device speech recognition. * swift-argument-parser (Apple): CLI utility support. These libraries are used locally within the App. We do not use them to collect, sell, or share user data. 7. Children's Privacy The App does not knowingly collect personal information from children under 13. The App does not require an account and does not transmit video, audio, or subtitle content to our servers. 8. Data Sharing We do not sell, trade, or share your videos, audio, subtitles, project files, or app preferences with third parties. The App is designed so that subtitle generation and project handling remain on your device. 9. Your Rights Because the App does not store personal data on our servers, there is no account data to request, export, or delete from us. You can delete locally stored App data by deleting the App from your device. You can also delete any exported videos from locations where you saved them, such as your Photo Library. 10. Changes to This Policy If we update this policy, we will revise the “Last updated” date above. Continued use of the App after changes constitutes acceptance of the revised policy.
