✅ shuttlecar collects no personal data, uses no analytics, requires no account, and sends nothing to any server. Everything stays on your Mac.
Overview
shuttlecar is a native macOS application for viewing and organizing images. It runs entirely on your device. There is no backend, no user account system, and no telemetry of any kind.
This policy explains what the app accesses locally and why.
What shuttlecar accesses
Your image files and folders
shuttlecar reads image files from folders you explicitly choose using the system file picker. It writes metadata back to files only when you click the Write button in the info panel. It never scans your disk, accesses files you haven't selected, or modifies files without your action.
Your location (for reverse geocoding)
If an image contains GPS coordinates in its EXIF data, shuttlecar can look up the place name using Apple's CoreLocation framework. This request goes to Apple's servers and is subject to Apple's privacy policy. No GPS data from your images is sent to any shuttlecar server — because there isn't one. Reverse geocoding only happens when you open the info panel for an image that has GPS data.
App preferences
shuttlecar stores your preferences (such as slideshow interval and tag hotkeys) locally using macOS standard storage (UserDefaults and local JSON files in your chosen folder). This data never leaves your Mac.
What shuttlecar does not do
- Does not collect analytics or usage data
- Does not transmit image files, metadata, or tags anywhere
- Does not require an account or login
- Does not use advertising frameworks
- Does not use crash reporting services
- Does not access your contacts, calendar, or any other system data
- Does not track you across apps or websites
Tags and sidecar files
Tags are stored in a tags.json file inside the folder you opened. This file is created and managed entirely by you on your own machine. shuttlecar never uploads or syncs this file anywhere.
Metadata writing
When you use the metadata editing features (Copyright, Artist, Keywords, etc.), changes are written directly into the image files on your disk using an atomic write — the original file is replaced safely. This is a local operation only. No metadata is transmitted externally.
Mac App Store
shuttlecar is distributed through the Mac App Store. Apple may collect aggregate, anonymized data about app downloads and crashes as part of their standard App Store operations. This is governed by Apple's privacy policy, not ours.
Children's privacy
shuttlecar does not collect any data from anyone, including children. There is nothing to report under COPPA or similar regulations.
Changes to this policy
If anything material changes about how shuttlecar handles data, this page will be updated with a new date. Given the app's design, meaningful changes are unlikely.
