Overview & Privacy-First Philosophy

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.

System Permissions & Apple Framework Usage

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.

Apple EventKit — Calendars

NSCalendarsUsageDescription

Purpose: Reads scheduled events, meetings, and appointments from your selected Apple Calendar accounts to assemble your integrated executive timeline and calculate free focus blocks.

Apple EventKit — Reminders

NSRemindersUsageDescription

Purpose: Reads and organizes task items, due dates, and priority flags from your selected Apple Reminders lists into your daily operational plan.

Data Storage & Apple iCloud Sync

On-Device Persistence (SwiftData)

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.

Apple iCloud & CloudKit

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.

Information We Do Not Collect

To ensure total clarity under Apple App Store Review Guidelines, Top Chief of Staff does not collect, track, or share any of the following:

  • No Personal Identifiers: We do not ask for or collect your name, email address, phone number, or physical address.
  • No Advertising SDKs: We do not include any third-party advertising frameworks, Google AdMob, Meta SDK, or data brokers.
  • No Analytics / Telemetry SDKs: We do not embed telemetry libraries, session recording tools, or third-party behavioral trackers.
  • No Data Sale or Brokering: We never sell, rent, license, or exchange user data to any external parties under any circumstances.

Network Traffic & External Reference Links

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:

  1. iCloud Multi-Device Sync: When configured by the user, background CloudKit sync communicates directly and securely between your device and Apple's iCloud infrastructure.
  2. External Associated Reference Links: When you tap a user-linked external document URL, web reference, or website, the destination URL is opened in Safari or your system default browser. That destination is governed by its own independent privacy policy.
6

Data Retention, Backup & User Erasure

Because Binary Gauss Studio does not store your data on external servers, you retain complete sovereignty over your information at all times:

  • Local Device Erasure: Deleting the Top Chief of Staff app from your iPhone, iPad, or Mac immediately and permanently removes all local application sandbox databases and cached files.
  • iCloud Data Management: You can manage or delete synced Top Chief of Staff data at any time through your Apple device settings: Settings > [Your Name] > iCloud > Manage Storage > Top Chief of Staff > Delete Data.
7

Security & Sandboxing Safeguards

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.

8

Children's Online Privacy (COPPA & GDPR-K)

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.
