Very Good Calendar Sync

Very Good Calendar Sync is a macOS application designed to keep work, personal, and client calendars perfectly aligned without compromising your privacy. The app runs entirely on your Mac, using native macOS Calendar.app access to synchronize events between any calendars you choose. This means your calendar data never leaves your device, no third-party services have access to your information, and no credentials are shared with external servers. The product is built for consultants managing multiple client calendars, employees balancing work and personal schedules, freelancers juggling various projects, and anyone tired of calendar chaos and double-bookings. With a one-time setup that takes approximately two minutes, the app monitors your calendars and syncs changes automatically in the background. New meetings on your work calendar appear on your personal calendar without any manual intervention. The app supports all calendar providers that work with macOS Calendar.app, including Google Calendar, Microsoft Outlook, Apple iCloud, and any CalDAV account. You maintain complete control over what gets synchronized, including specific weekdays, daily hours, start dates, and the level of event detail shared. The first synchronization between two calendars is completely free, with affordable monthly, annual, and lifetime plans available for users who need multiple synchronizations.

Clone or Redact

Share your availability without sharing your personal life by choosing how much event detail to reveal. You can clone events with full details including title, description, and location, or redact them to show only that you are busy. This feature gives you precise control over what others see, keeping sensitive information private while still maintaining accurate availability across all your calendars.

Stays Out of the Way

The application runs quietly in your menu bar and requires no ongoing attention after initial setup. Once you configure your synchronization preferences, the app automatically monitors your calendars and syncs changes whenever they occur. This hands-off approach means you can focus on your work and personal life without constantly checking or manually updating multiple calendars.

Filter by Day and Time

Each synchronization gets its own set of rules, allowing you to control exactly when events are shared. You can synchronize only weekdays, weekends, or pick specific days of the week. Additionally, set a time range to limit syncing to specific hours, such as 9 AM to 6 PM only. This granular control ensures that only relevant events are shared with the appropriate calendar.

No Accounts to Link

Your Google, Microsoft, and Apple credentials remain secure under macOS Internet Accounts system. There are no logins on third-party websites or external services to manage. The app works directly with the calendar accounts you have already configured on your Mac, eliminating the need to create new accounts or share passwords with any additional service.

Consultants Managing Client Calendars

Consultants often work with multiple clients, each with their own calendar system and scheduling preferences. Very Good Calendar Sync allows you to maintain separate client calendars while keeping your personal schedule synchronized across all of them. You can set specific rules for each client, such as only sharing business hours or redacting event details to protect confidentiality. This eliminates manual cross-checking and reduces the risk of double-bookings that can damage professional relationships and credibility.

Employees Balancing Work and Personal Schedules

Professionals who use separate work and personal calendars often struggle with conflicts when personal appointments overlap with work commitments. With Very Good Calendar Sync, you can automatically sync your dentist appointments, family events, or other personal obligations to your work calendar as busy time blocks. Your colleagues see your real availability without seeing the details of your personal life, preventing scheduling conflicts while maintaining boundaries between work and personal time.

Freelancers Juggling Multiple Projects

Freelancers frequently manage calendars for different clients, projects, and their own administrative tasks. Very Good Calendar Sync enables you to keep all these calendars in harmony without manually updating each one. You can set unique synchronization rules for each client relationship, such as only sharing weekday availability or limiting synced hours to specific project windows. This ensures you never overcommit and maintain accurate availability across all your professional engagements.

Agencies and Cross-Functional Teams

Agencies and teams that coordinate between internal operations and client-facing activities face unique scheduling challenges. Very Good Calendar Sync allows team members to maintain internal calendars while synchronizing relevant availability to client-facing systems. This creates a single source of truth for scheduling without exposing internal meetings, strategy sessions, or confidential discussions. Everyone sees the same real-time availability, reducing confusion and improving coordination across the entire organization.

Do you store any of my calendar data?

No, Very Good Calendar Sync does not store any of your calendar data. The application runs entirely on your Mac and uses your device's native calendar access to read and write events. There are no servers of its own, no data collection systems, and no analytics monitoring your calendar activity. Your calendar data never leaves your Mac, and nothing is transmitted externally. This on-device approach ensures complete privacy and security for all your scheduling information.

Which calendar providers are supported?

Very Good Calendar Sync supports any calendar that appears in macOS Calendar.app. This includes Google Calendar, Microsoft Outlook and Exchange, Apple iCloud, and any CalDAV account. There is no extra setup required because the app works directly with the calendar accounts you have already configured on your Mac. If you can see a calendar in macOS Calendar.app, it will work with Very Good Calendar Sync without any additional connections or third-party access.

Does it sync when my Mac is off or asleep?

Very Good Calendar Sync requires your Mac to be powered on and awake to perform synchronization. The app monitors your calendars and syncs changes in the background while your Mac is active. When your Mac goes to sleep or is turned off, synchronization pauses and automatically resumes when your device is awake again. This is consistent with how macOS handles background processes and ensures your calendar data remains secure on your device.

Is this app available for Windows or iOS?

Very Good Calendar Sync is currently available exclusively for macOS. The application is built directly into the macOS ecosystem and works with the native Calendar.app. There are no versions available for Windows or iOS at this time. The app requires macOS to function because it relies on the operating system's native calendar access and Internet Accounts system for secure credential management.

For users who need multiple synchronizations, three paid plans are available. The Monthly plan costs 1.99 pounds per month with flexible month-to-month billing and cancellation at any time.
