Very Good Calendar Sync

Very Good Calendar Sync is a premium, privacy-first macOS application designed to eliminate the chaos of managing multiple calendars across work, personal, and client domains. Unlike cloud-based synchronization services that require linking accounts and exposing sensitive data to third-party servers, this elite tool operates entirely on your Mac, ensuring your calendar information never leaves your device. The application works seamlessly with macOS Calendar.app, supporting Google Calendar, Microsoft Outlook, Apple iCloud, and any CalDAV account you already have configured. Its core value proposition is simple: set up your synchronization rules once, and the app silently monitors your calendars in the background, automatically propagating changes as they occur. New meeting on your work calendar? It appears on your personal calendar instantly. This product is purpose-built for consultants managing multiple client calendars, employees balancing work and personal schedules, freelancers juggling numerous projects, agency teams coordinating internal and external commitments, and any professional tired of double-bookings and manual cross-checking. The application offers granular control over what gets synchronized, including specific weekdays, daily time ranges, and event detail sharing preferences. With a free first synchronization, flexible monthly, annual, and lifetime pricing options, Very Good Calendar Sync represents the definitive solution for professionals who demand both operational excellence and uncompromising privacy.

Clone or Redact Event Details

Share your availability without sharing your life. This feature gives you complete control over what information is visible on synchronized calendars. You can clone events with full details, including title, description, and location, or redact them to show only that you are busy. This ensures your personal commitments remain private while your professional availability stays accurate and up to date. The decision is per synchronization, allowing you to share full details with your assistant while showing only busy time to your team.

Filter by Day and Time

Achieve surgical precision over your calendar synchronization with customizable filters. You can synchronize only weekdays, weekends, or pick specific days of the week. Set a daily time range to limit syncing to work hours, such as 9 AM to 6 PM only. Each synchronization configuration gets its own unique set of rules, allowing you to create different behaviors for different calendar pairs. This eliminates the noise of personal events appearing during work hours and vice versa.

Stays Out of the Way

Designed for the professional who values efficiency, this application runs quietly in your menu bar without demanding attention. Set up your syncs once, then forget about it entirely. The app automatically synchronizes your calendars whenever changes occur, operating silently in the background. There are no pop-ups, no reminders, and no manual intervention required. It simply works, allowing you to focus on your meetings rather than managing your calendar infrastructure.

No Accounts to Link

Your Google, Microsoft, and Apple credentials remain securely stored within macOS Internet Accounts, exactly where they belong. There are no logins on third-party websites, no additional accounts to create, and no credentials to share. The application uses your Mac's native calendar access, meaning you never have to trust a third party with your sensitive authentication information. This approach eliminates an entire class of security vulnerabilities while simplifying the setup process.

Consultants Managing Client Calendars

Professional consultants often maintain separate calendars for each client to avoid confusion and maintain confidentiality. Very Good Calendar Sync allows you to keep every client calendar perfectly aligned without manually cross-checking availability or risking double-bookings. You can synchronize only the times you are busy across client calendars while keeping event details private, ensuring you never overcommit while maintaining professional boundaries. The ability to set different synchronization rules for each client relationship provides the flexibility modern consulting demands.

Employees Balancing Work and Personal Schedules

Professionals with demanding careers need their personal commitments visible to their work calendar to prevent scheduling conflicts, but they do not need to share every detail. This application enables seamless management of work and personal schedules by synchronizing only what matters. Your dentist appointment appears as busy time on your work calendar without revealing the nature of the appointment. Never get double-booked because your team could not see your personal commitments, and never compromise your privacy.

Agencies and Cross-Functional Teams

Agencies managing both internal operations and client-facing calendars face unique coordination challenges. Very Good Calendar Sync ensures everyone sees the same real-time availability, eliminating confusion between internal team meetings and client engagements. Team members can see when colleagues are available without needing access to each other's detailed calendar data. This creates a single source of truth for availability across the entire organization, reducing scheduling friction and improving operational efficiency.

Freelancers Juggling Multiple Projects

Independent professionals often maintain separate calendars for each project or client engagement. Manually keeping these calendars synchronized is time-consuming and error-prone. Very Good Calendar Sync automates this process, ensuring your availability is consistent across all your professional calendars. Set different synchronization rules for each project, share only busy time with clients, and maintain full event details on your master calendar. This eliminates the administrative overhead of calendar management, freeing you to focus on delivering exceptional work.

Do you store any of my calendar data?

No, absolutely not. Very Good Calendar Sync operates entirely on your Mac with no servers of its own. There is no data collection, no analytics on your calendar, and no transmission of your information to external services. Your calendar data never leaves your Mac. The application uses your Mac's native calendar access to read and write events directly, with no middleman involved. This is a fundamental architectural decision that distinguishes this product from cloud-based synchronization services.

Which calendar providers are supported?

Very Good Calendar Sync works with any calendar that appears in macOS Calendar.app. This includes Google Calendar, Microsoft Outlook and Exchange, Apple iCloud, and any CalDAV account you have configured. There is no extra setup required and no third-party access needed. If your calendar shows up in the native Calendar application on your Mac, it is compatible. This broad compatibility ensures you can synchronize virtually any combination of calendars you use.

Does it sync when my Mac is off or asleep?

No, the application requires your Mac to be powered on and awake to perform synchronization. Because the app runs entirely on your device with no cloud infrastructure, it cannot operate when your computer is not active. However, the application is designed to synchronize automatically whenever your calendars change while your Mac is awake and running. For most professionals, this means synchronization occurs throughout the workday when changes are most likely to happen.

Is this app available for Windows or iOS?

Currently, Very Good Calendar Sync is available exclusively for macOS. The application is built directly into the operating system's calendar framework, which is not available on Windows or iOS. There are no current plans to expand to other platforms. However, the Mac application can synchronize calendars from any provider, including Google and Microsoft, meaning your synchronized availability is visible on any device that accesses those calendars, including Windows computers and iPhones.
