Very Good Calendar Sync

Very Good Calendar Sync is a macOS application designed to eliminate the chaos of managing multiple calendars across different platforms. It runs quietly on your Mac, synchronizing events between any calendars available in macOS Calendar.app, including Google Calendar, Microsoft Outlook, Apple iCloud, and any CalDAV account. The core value proposition is simplicity and privacy: you set up your synchronization rules once, and the app handles everything automatically in the background. New events on your work calendar appear on your personal calendar without any manual intervention. This tool is built for consultants managing client calendars, employees balancing work and personal schedules, freelancers juggling multiple projects, and anyone tired of double-bookings and calendar confusion. What sets Very Good Calendar Sync apart is its commitment to privacy. Your calendar data never leaves your Mac. There are no credentials to share, no third-party servers, no cloud storage, and no analytics tracking your events. The app uses your Mac's native calendar access, meaning nothing is transmitted externally. This on-device approach ensures your sensitive meeting details remain completely under your control. The first synchronization between two calendars is free, making it easy to try before committing to a paid plan.

Clone or Redact Events

Share your availability without sharing your life. When synchronizing events, you have full control over what information gets shared. Choose to clone events with full details, including title, description, and location, or redact them to show only that you are busy. This feature is essential for professionals who need to block time on client calendars without exposing the specifics of internal meetings, personal appointments, or confidential projects. Your private information stays private.

Filter by Day and Time

Each synchronization can have its own custom rules for when events should be shared. You can choose to synchronize only on weekdays, weekends, or pick specific days of the week. Set a daily time range to limit syncing to work hours, for example from 9 AM to 6 PM only. You can also set a start date for synchronization. This granular control ensures that only the events you want to share, during the times you want to share them, appear on your other calendars.

Stays Out of the Way

Very Good Calendar Sync is designed to be unobtrusive. It runs quietly in your Mac's menu bar, requiring no ongoing attention. You set up your syncs once, configure the rules, and then forget about it. The application automatically synchronizes your calendars whenever changes occur, whether you add a new event, modify an existing one, or cancel a meeting. There are no pop-ups, no reminders, and no manual steps needed after the initial configuration.

Built into macOS

The application works directly with macOS Calendar.app, eliminating the need to install additional apps or configure complex connections. Your calendars are already set up in Calendar.app, and Very Good Calendar Sync simply taps into that existing infrastructure. There is no extra setup required to connect to Google, Microsoft, or iCloud accounts. The app uses the same native calendar access that macOS provides, making the integration seamless and reliable.

Consultants Managing Client Calendars

Consultants often work with multiple clients, each using their own calendar system. Manually cross-checking availability across these calendars leads to double-bookings and scheduling errors. Very Good Calendar Sync allows consultants to keep every client calendar synchronized automatically. A consultant can set up rules to share only busy/available time with clients while keeping meeting titles and descriptions private. This ensures accurate availability without exposing sensitive internal information.

Employees Balancing Work and Personal Schedules

Professionals who use separate work and personal calendars face constant friction. A dentist appointment might be on a personal calendar, but colleagues cannot see that time is blocked. Very Good Calendar Sync bridges this gap by synchronizing personal events to the work calendar as busy time. Employees can choose to redact event details, showing only that they are unavailable during specific hours. This prevents double-bookings while maintaining privacy around personal commitments.

Freelancers Juggling Multiple Projects

Freelancers often manage calendars for different clients, projects, and their own personal life. Keeping these calendars consistent without manual effort is a significant challenge. Very Good Calendar Sync enables freelancers to set up synchronization rules for each client relationship. They can filter by specific weekdays and time ranges, ensuring that client A sees availability only during agreed-upon working hours, while client B sees a different schedule. The automation eliminates the risk of accidentally double-booking across projects.

Agencies and Cross-Functional Teams

Agencies that manage both internal team calendars and client-facing calendars need a reliable way to keep everyone aligned. Confusion arises when internal meetings are not reflected on client calendars, or vice versa. Very Good Calendar Sync allows agencies to synchronize calendars with custom rules for each relationship. Internal events can be redacted to show only busy time on client calendars, while client meetings appear as full details on internal calendars. Everyone sees the same real-time availability, reducing scheduling friction.

Do you store any of my calendar data?

No. Very Good Calendar Sync runs entirely on your Mac. It uses your Mac's native calendar access to read and write events directly. The application has no servers of its own, no cloud storage, and no data collection services. Your calendar data never leaves your device. There are no analytics, no logging of your events, and no third-party access to your information. This on-device approach is a core design principle of the product.

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. If you can see a calendar in Calendar.app on your Mac, you can synchronize it with Very Good Calendar Sync. There is no need to install additional apps or configure separate connections for each provider. The app leverages the existing calendar infrastructure on your Mac.

Does it sync when my Mac is off or asleep?

No. Very Good Calendar Sync requires your Mac to be powered on and awake to perform synchronizations. The application runs in the background and monitors calendar changes, but it cannot operate when the computer is in sleep mode or turned off. When you wake your Mac or turn it on, the app will detect any changes that occurred while it was unavailable and synchronize them accordingly. For continuous synchronization, ensure your Mac remains awake during your working hours.

Is this app available for Windows or iOS?

Currently, Very Good Calendar Sync is available exclusively for macOS. There is no Windows version or iOS app at this time. The application is designed to integrate deeply with macOS Calendar.app and the native calendar access provided by the operating system. If you use a Mac as your primary computer, you can use this app to synchronize calendars across all your accounts. For mobile access, the synchronized events will appear on your iPhone or iPad through your existing calendar accounts.

Very Good Calendar Sync offers three pricing plans to suit different needs. The first synchronization between two calendars is completely free with no payment required.
