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 Pro 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
When you enable Smart translation mode, the titles, notes, and locations of individual calendar events are transmitted through our proxy infrastructure to Google's Gemini AI model for the purpose of language translation. On macOS (via Mac Catalyst), Smart mode is applied by default because Apple's on-device translation framework is unavailable on that platform. You may select Apple Translate mode on iOS at any time to perform all translation entirely on-device without transmitting event content to external services.

1.5 Calendar Search Queries
If you use the public calendar search feature, the search terms you enter are transmitted through our proxy infrastructure to Perplexity's API to identify matching publicly available calendar feeds. Search queries do not include calendar event content.

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
We collect anonymized usage analytics through PostHog to understand feature adoption and improve the Service. Analytics events are associated with a randomly generated device-level identifier and do not include your name, email address, account credentials, or calendar content. We do not sell or share analytics data with third parties for advertising purposes. Crash reports and diagnostic data may also be made available to us through Apple's platform services to support stability and performance improvements.
