1.1 Account Information
When you register or authenticate through Sign in with Apple or Google Sign-In, we receive and store your name, email address, and a stable account identifier issued by the respective identity provider. This information is used solely to establish and maintain your account and to synchronize your subscription status across your devices.

1.2 Calendar and Event Data
To provide the core functionality of the Service, we store the events, tasks, reminders, titles, descriptions, dates, times, locations, and related preferences that you create or manage within the app. This content is stored locally on your device and synchronized to your private iCloud account through Apple's CloudKit infrastructure. We do not store or access your calendar content on our own servers in the ordinary course of providing the Service.

1.3 Purchase and Subscription Data
If you purchase a paid CallyList subscription, the transaction is processed through Apple's App Store using Apple's StoreKit framework and RevenueCat's subscription management platform. We receive and retain subscription status, entitlement identifiers, and transaction-related metadata sufficient to verify your subscription and facilitate purchase restoration. Payment card details are processed exclusively by Apple and are not accessible to us.

1.4 Translation Content
On supported iPhone and iPad devices, CallyList uses Apple’s Translation framework to translate event titles, locations, notes, and to-do text. Translation is processed on your device after any required Apple language model has been downloaded. CallyList does not send calendar or to-do content to its servers or to a third-party AI translation provider for translation. Apple Translate is not currently available in the Mac version of CallyList.

1.5 Calendar Search Queries
If you use public calendar search, the search terms you enter are sent through CallyList’s Cloudflare Worker to Perplexity to identify matching publicly available calendar feeds. Existing calendar events, notes, locations, and to-do content are not included in these requests.

1.6 Image Data
You may choose to attach an image to a calendar event by selecting a photo from your device's photo library. Image selection is performed locally on your device. Selected image data is stored as part of the event record and synchronized to your private iCloud account via CloudKit. Image data is not transmitted to our servers.

1.7 Diagnostic and Usage Data
Usage analytics are optional and disabled by default. If you enable Usage Analytics in CallyList Settings, the app sends product-interaction and limited crash and performance diagnostic signals to TelemetryDeck to help us understand feature adoption, stability, and performance. These signals use a pseudonymous device identifier and do not contain your name, email address, account credentials, calendar events, to-do items, notes, locations, or other calendar content. You may withdraw consent at any time by turning off Usage Analytics in Settings. Turning analytics off stops future analytics collection by CallyList. We do not use analytics information for advertising or cross-app tracking.

1.8 Location Data
If you enable weather, CallyList uses your device’s location while the app is in use to request a local forecast from Apple WeatherKit. CallyList does not store your location on its servers or link it to your CallyList account. Apple processes WeatherKit requests under Apple’s applicable privacy terms.

1.9 On-Device-Only Features (Face ID and Voice Dictation)
CallyList offers optional Face ID app lock and voice dictation for event titles and to-do items. Both are processed entirely on your device through Apple's system frameworks — CallyList never receives, stores, or transmits any biometric data or audio recording, and no data from these features leaves your device.

1.10 Notifications and CloudKit Updates
CallyList uses local notifications, scheduled entirely on your device, to remind you of upcoming events. Separately, the app registers for Apple's silent push notifications solely so CloudKit can promptly deliver calendar updates across your devices — we do not send promotional or marketing push notifications, and this registration does not give us access to your device's push token or any way to contact you directly.

1.11 Local Backup Data
To help protect against data loss, CallyList periodically saves a backup copy of your events and to-dos directly on your device. This backup never leaves your device and is not transmitted to our servers or any third party.
