Privacy Policy — WeekNo.

Last updated: March 1, 2026

Overview

WeekNo. is a week number utility app for iOS and Apple Watch. Your privacy is simple: we collect nothing.

Data Collection

WeekNo. does not collect, store, transmit, or share any personal data. The app:

• Does not require an account or login
• Does not use analytics or tracking
• Does not use cookies
• Does not access your contacts, location, photos, or any other personal information
• Does not connect to any server or external service
• Runs entirely on your device

Stored Preferences

WeekNo. stores your chosen theme, font style, and week system preferences locally on your device using standard system storage (UserDefaults). These preferences are synced between your iPhone and Apple Watch using Apple’s built-in WatchConnectivity framework — this is a direct device-to-device transfer and no data is sent to any server. Preferences are automatically deleted when you uninstall the app.

Third-Party Services

WeekNo. uses no third-party services, SDKs, or frameworks beyond Apple’s built-in system frameworks (SwiftUI, WidgetKit, WatchConnectivity).

Children’s Privacy

WeekNo. does not collect any data from anyone, including children under 13.
