Privacy & Permissions

This page explains the permissions macOS 2.1 uses and how it handles data. For the full legal details, see the Privacy Policy.

Permissions​

PermissionWhen it's usedWhat for
NotificationsAsked the first time you open the appPush notifications and departure reminders
Files you chooseWhen you use the file chooser or drag files inCheck-in photos, trip photos, forum and chat attachments, importing boarding passes, PDFs, calendar files, and GPX/KML, and ID images for identity verification; the app reads only the files you choose
Sign in with AppleWhen you choose to sign in with AppleSigning in with your Apple Account
iCloudAutomatically, when your Mac is signed in to iCloudSyncing travel data

The macOS version doesn't ask for camera, microphone, photo library, contacts, or calendar access. The macOS version has no ads and doesn't use third-party analytics tools.

iCloud Sync​

Your travel data is stored in your iCloud, in the same container as the iPhone and iPad versions. It syncs whenever your Mac is signed in to iCloud, whether or not you're signed in to a YUCTS account. If your Mac isn't signed in to iCloud, your data is kept only on this Mac.

DataHow it syncs
Trips, expenses, lists, shopping, journal, saved places, categoriesQuick Sync + iCloud database
Places, bookings, documents, companionsiCloud database
PhotosInfo via iCloud; originals need a YUCTS sign-in
Transport modes, flight seatsThis device only
  • "Quick Sync" is iCloud key-value sync; the "iCloud database" is your private iCloud database (same Apple Account).
  • The sync status and "Sync now" are in Settings → iCloud Sync. The system schedules the iCloud database on its own, so the app can't force it to finish immediately; results appear once iCloud responds.
  • The app's settings (such as the layout, notification sound, and festival Dock icon) and your reading history are kept on this Mac only and aren't synced through iCloud.

Data Sent to Servers​

When you use these features, the related data is sent to the YUCTS server or a third-party service:

FeatureData sent
Signing inYour username and password are sent over an encrypted connection for verification. The device name is sent as a generic "Mac (macOS version)", not your computer's name
AI AssistantYour questions and conversation, sent to the YUCTS server and passed to an AI service provider to generate answers; conversation history is stored on the server and can be deleted
⌘K searchSearch terms, sent to the YUCTS server (forum searches run as you when you're signed in)
Order importThe confirmation email text you paste, sent to the YUCTS server to be read
Importing boarding passes, PDFs, and calendar filesNot uploaded; read on this Mac only
Trip photosLocation and other metadata are removed before upload, keeping only the orientation and color profile
Check-in photosLocation (GPS), device serial number, and editing history are never made public; you can choose "Don't keep EXIF data"
Forum and chat attachmentsImages are re-encoded with metadata removed before upload
Identity verificationThe ID images you choose, sent to the site team for review

Push notificationsThis Mac's push registration and push preferences
Article view countsWhen you actually read an article for 3 seconds or more, the article number is sent (at most once per article every 30 minutes), with no device or member identifier
Local WeatherThe location's coordinates, sent to Open-Meteo (without your identity)
Explore nearbyThe city and category you search, sent to Apple Maps

Handling Sensitive Data​

  • Documents: sensitive details such as passport numbers are never decrypted or shown on the Mac; only a summary is shown.
  • Boarding passes: barcodes, booking codes, and passenger names are read on this Mac only and aren't uploaded or logged. Passenger names aren't saved, and seats and e-ticket numbers are kept on this device only.
  • Sign-in: your sign-in token is stored in this Mac's keychain, on this device only, and isn't synced to other devices through iCloud Keychain. The app doesn't store your password.

Cache & Storage​

In Settings (⌘,) → Cache & Storage, you can:

  • See your "Local Storage": the article cache, forum cache, image cache, user guide, system status, and offline saved articles (which aren't cleared).
  • Set the "Image cache limit".
  • Click "Clear Re-downloadable Cache": cached articles, forum content, images, the user guide, and system status are deleted and downloaded again when needed. Your trips, lists, travel expenses, journals, bookmarks, offline bookmarks, drafts, pending shares, and sign-in status aren't deleted.

Signing out stops push notifications to this Mac and clears your member data from this Mac; your trips are stored in your iCloud and aren't affected.
