Terms of use

Effective November 1, 2026. Orbweft Star Trails · Gobling Company.

Purchase and use

The app is a paid-upfront utility without a subscription. Apple controls regional pricing, purchase processing, availability and refund requests. The Apple standard end-user license agreement applies unless another agreement is shown by Apple.

Your sources and results

Process images you have permission to use. You retain your rights in your source images and results. The bundled synthetic example demonstrates the workflow; it is not a real night-exposure sequence or a promise of a particular photographic result.

Processing limitations

Use a fixed camera and matching image dimensions. Excluded exposures can leave gaps. The app uses decoded 8-bit sRGB values, with optional dark subtraction and first-frame foreground preservation. No sky registration, RAW development, gap filling, automatic aircraft removal or video capture is provided.

Keep your important files

Keep source originals and important outputs separately. Processing ZIPs do not include original sources and cannot restore an editable session. Local app data is removed when you delete it or remove the app. Contact maga40@naver.com for support.
