In compliance with Apple App Store Review Guidelines (Section 5.1.1) and App Store Connect Privacy Details, the following summarizes the data practices of Top Chief of Staff:

No account creation is required. No contact information, device IDs, or usage history are collected by Binary Gauss Studio.

Multi-device sync uses your private Apple iCloud database. We have zero access to your data.
Binary Gauss Studio Inc., in collaboration with Brent Goss ("we", "us", or "our") builds applications with a fundamental commitment to privacy-by-design. Top Chief of Staff is an agenda briefing, timeline, and contact assistant designed for iPhone, iPad, and macOS (Designed for iPad).
We believe that your personal and professional schedule, prioritized tasks, and relationship milestones are private to you. Top Chief of Staff operates under an offline-first, client-only architecture. All algorithmic scheduling, briefing generation, and contact milestone calculations take place entirely on your Apple device. Binary Gauss Studio maintains no server infrastructure that captures, stores, analyzes, sells, or monetizes your schedule or contact information.
To deliver executive briefings and synthesize your daily timeline, Top Chief of Staff requests explicit user permission for specific iOS/macOS system frameworks. You may grant, revoke, or restrict these permissions at any time via Settings > Privacy & Security on your Apple device.

Privacy Guarantee: Calendar data is accessed in real time, evaluated purely in local device RAM, and is never transmitted over the network to Binary Gauss Studio, third parties, or remote artificial intelligence processors.
NSRemindersUsageDescriptionPurpose: Reads and organizes task items, due dates, and priority flags from your selected Apple Reminders lists into your daily operational plan.
Privacy Guarantee: Reminders access is restricted strictly to on-device scheduling operations. Your task details, titles, and completion statuses remain solely within your local device ecosystem.
NSContactsUsageDescriptionPurpose: Identifies upcoming birthdays, anniversaries, and notable family or executive life events from your device's address book to display in your daily briefing cards.
Privacy Guarantee: Top Chief of Staff does not harvest, compile, upload, or share your address book. Contact names and milestone dates are filtered exclusively in-memory on your device.
User-defined priorities, custom agenda configurations, associated reference URLs, and application preferences are persisted locally on your device within the sandboxed application container using Apple SwiftData / CoreData. This data is protected by Apple iOS/macOS Data Protection hardware encryption.
When iCloud synchronization is enabled, Top Chief of Staff syncs user-created metadata across your personal iPhone, iPad, and Mac devices using Apple CloudKit. All data is deposited exclusively in your private iCloud container. This data is encrypted in transit and at rest using keys tied to your Apple ID. Binary Gauss Studio has no access to your private database container, cannot inspect your synced records, and does not maintain any shadow servers or mirrors.
To ensure total clarity under Apple App Store Review Guidelines, Top Chief of Staff does not collect, track, or share any of the following:
Top Chief of Staff does not initiate background telemetry pings or network calls. The application only interacts with the network under the following user-directed scenarios:
Because Binary Gauss Studio does not store your data on external servers, you retain complete sovereignty over your information at all times:
Top Chief of Staff executes inside Apple's strict application sandbox on iOS, iPadOS, and macOS. The app utilizes native Swift and SwiftUI APIs without executing unverified third-party binaries or native dynamic libraries. All inter-process communication with EventKit and Contacts is strictly gated by Apple's operating system security controls, requiring explicit user authorization before any data can be accessed.
Top Chief of Staff is an executive and productivity assistant intended for general audiences. The application does not knowingly collect personal information from children under 13 (or under 16 in certain European jurisdictions). Because the application collects zero personal information on remote servers, no children's data is acquired, processed, or retained by Binary Gauss Studio Inc.
