Overview
Plan Book is a daily planner for iPhone. It works without an account and is designed not to collect personal information.
Data collection
Plan Book does not collect, sell, rent, or share personal data. The app does not include advertising, analytics SDKs, or cross-app tracking.
Planner content
Task titles, notes, locations, categories, colors, completion status, and schedule information are stored locally on your device. Plan Book does not transmit this content to the developer.
Notifications
If you enable a reminder, iOS schedules a local notification on your device. You can turn reminders off in Plan Book or change notification permission in iOS Settings.
Widgets
Home Screen and Lock Screen widgets read a limited task summary from an Apple app group shared only by Plan Book and its widget extension.
Data deletion
You can delete individual items inside the app. Removing Plan Book from your device deletes its locally stored app data, subject to normal iOS device backup behavior.
プライバシーポリシー
Plan Bookはアカウントなしで利用でき、個人情報を収集しません。タスク、メモ、場所、カテゴリー、色、完了状況、予定は端末内に保存され、開発者へ送信されません。広告、分析SDK、アプリ間トラッキングは使用していません。リマインダーはiOSのローカル通知として端末上で処理されます。
