Fourshadow
Privacy
Fourshadow is built around the idea that the year is yours to notice. Your data is yours too. This policy describes, in plain English, what the app does and doesn't do with information.
Short version
- No accounts, no sign-up, no email collection.
- No analytics, no tracking, no third-party advertising SDKs.
- Your location, photos, and check-ins stay on your device and in your iCloud.
- We never receive your data on our servers — because we don't have any.
What the app collects
Location. The app asks for your location ("when in use") so it can compute the sun and moon position above your sky, choose the right seasonal palette, and pick the phenology content that fits your hemisphere and climate zone. Location is read at launch and when the app comes to the foreground. It stays on your device. We don't transmit it to any server we control.
Photos. When you add a photo to the phenology wheel or to a creative check-in, the app reads the image through Apple's PhotosPicker and stores a downsampled copy locally. If you have iCloud sync enabled for the app, those photos are mirrored to your private iCloud database via CloudKit. We never see or store them.
Notification preferences. If you opt in to seasonal-change notifications or the daily creative-cycle reminder, your preferences (time of day, on/off) live in the app's local settings. The notifications themselves are scheduled locally with iOS and never go through any remote service.
Check-in entries. Your daily In/Out marks, notes, and attached photos in the Creative Cycle are stored locally via SwiftData and synced to your iCloud through CloudKit's private database. Apple does not give us access to your iCloud data, and we don't request it.
What the app does NOT collect
- No analytics events, no usage telemetry, no crash reporters that link to you.
- No advertising identifiers, no IDFA tracking.
- No contacts, calendars, microphone, or health data.
- No purchase history, no IAP — the app has no in-app purchases.
- No third-party SDKs of any kind beyond Apple's frameworks.
Third-party services
Apple services. The app uses Apple's WeatherKit for the weather card, CloudKit for iCloud sync of your wheel and check-in data, and standard iOS frameworks for notifications, location, and photos. Apple's privacy policy governs how it processes this data. We don't receive any of it.
CelesTrak. To show ISS pass times on the Tonight tab, the app fetches the publicly available International Space Station orbital data (a "TLE") from celestrak.org. This is an anonymous, unauthenticated HTTP request. CelesTrak receives only a routine request log entry — no personal information is sent.
Children
Fourshadow is rated 4+ and contains no objectionable content. It does not knowingly collect any personal information from anyone — including children under 13.
Your control
You can revoke location or photo access at any time in iOS Settings → Fourshadow. You can disable notifications in iOS Settings → Notifications → Fourshadow. To delete all data, uninstall the app and delete the Fourshadow record from iCloud Drive → Manage Storage. Because no data ever leaves your devices, deletion is complete and final.
Changes
If this policy ever changes, the "Last updated" date above will change with it. Material changes will be announced in the app's What's New release notes.
