No separate app account
You can use the calculator and local purchase history without creating an account with us. Optional Shared Trips require an Apple Account signed in to iCloud. Apple processes App Store purchases and restores through StoreKit; we do not receive your full payment-card details from Apple.
Information stored on your device
The app stores settings, card labels and fee settings, trips, member names, purchase amounts, dates, vendors, categories, notes, assignments and split details locally. Receipt images you attach are stored as local files. This information supports the app's features and is not sold. Device backups may include app data according to your Apple and device settings; local storage does not mean that device backups are disabled.
Optional Shared Trips and iCloud
Creating or joining a Shared Trip allows eligible trip information to be stored and synchronised through Apple's iCloud and CloudKit services. This includes members, shared purchase details and notes, allocations, balances, repayments and activity. People invited to the trip can access the information shared with that trip. Do not put passwords, full card numbers or other secrets in card names, transaction notes or trip details.
The sharing controls determine which purchases are included in the shared snapshot. When sharing all transactions is switched off, eligible single-member purchases are kept out of that snapshot. The internal-family sharing control can also exclude purchases wholly within a family. A purchase involving another member or household, including use of another member's card, may still be shared to calculate balances. These are trip settings, not an individual participant's private viewing preference.
Excluded purchases are retained locally rather than uploaded to a separate private CloudKit backup by this app. After a sharing setting is changed and saved, the updated shared data must synchronise to other devices. An offline device may still have an earlier copy. Turning sharing off cannot recall exports, screenshots or copies previously retained by another person. Earlier app versions may handle sharing differently, so all participants should use an up-to-date version.
Receipt scanning, photos and notes
Receipt text recognition uses Apple's on-device Vision framework. Attaching an image does not automatically upload its image file to the Shared Trip's CloudKit snapshot. A transaction note is part of its purchase details and is shared if that purchase is shared. If you choose to save a receipt to Photos, the image is also subject to your Photos and iCloud Photos settings. Camera and photo access can be managed in device settings.
Notifications
Shared Trip alerts are optional and use Apple's notification services. The notification privacy update uses generic alert text rather than including member names, amounts, merchants, notes or trip names in alert content. Older app versions may display more detail; updating every participating device is recommended. You can switch Shared Trip alerts off in the app or manage notification permission in device settings.
Exchange rates, tax data and app updates
The app requests reference rates from ExchangeRate.fun and Frankfurter, and may request reference tax data when a remote tax-data source is configured. These requests can include currency codes; the app does not attach your purchase history, notes or receipt images to reference-rate requests. It also checks Apple's App Store service for app-version information. Providers receive normal network information, such as your IP address and request metadata, and handle that information under their own policies. Cached reference data is stored locally.
Optional location access
If you choose location-based region selection, the app uses your location while in use to identify a country, state, province, county or city and estimate tax. Apple's location and reverse-geocoding services may process location data to provide this feature. Precise coordinates are not stored in purchase history or sent with exchange-rate requests. Selected region information may appear in purchase details. You can decline or disable location permission and choose a destination manually.
Retention and deletion
Local history and settings are retained until you remove or replace them using the app, or remove its local data through your device. Deleting a purchase removes its History entry and its locally attached receipt image. Archiving a trip only changes its visibility; it is not deletion.
Deletion of a shared purchase must synchronise before other devices reflect it. A trip owner can use the app's delete-for-everyone option to remove the trip's active shared data; removing a trip only from your device or leaving a share does not necessarily delete the owner's or other participants' copies. Shared repayments are maintained separately from purchases. Previously exported CSV, PDF or backup files, Photos copies and device or iCloud backups are not erased by deleting a transaction in the app. Apple controls its service-side backup and retention processes.
To withdraw sharing, change the applicable trip settings or leave the share; to withdraw optional permissions, use the app or device settings. Keep any export you need before deleting data. We do not operate a separate account server containing your local purchase history and cannot remotely erase data stored only on your device. Contact us for help identifying the applicable deletion steps.
