Very Good Calendar Sync

Very Good Calendar Sync is a macOS application designed to solve the common problem of managing multiple calendars across work, personal, and client accounts. The app runs entirely on your Mac, synchronizing events between any calendars available in macOS Calendar.app, including Google Calendar, Microsoft Outlook, Apple iCloud, and any CalDAV account. Its core value proposition is providing automatic, private calendar synchronization without requiring users to link accounts or expose sensitive data to third-party servers.

The product is built for consultants managing client calendars, employees balancing work and personal schedules, freelancers juggling multiple projects, and anyone tired of calendar chaos. After a simple two-minute setup, 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 effort.

What sets Very Good Calendar Sync apart is its commitment to privacy and control. Your calendar data never leaves your Mac. There are no credentials to share, no third-party access, and no cloud storage involved. The app uses your Mac's native calendar access, and nothing is transmitted externally. Users maintain complete control over what gets synchronized, including the ability to choose specific weekdays, set daily hours, define start dates, and decide whether to share all event details or only the time you are busy. The app runs quietly in your menu bar and synchronizes automatically whenever your calendars change, making it a set-and-forget solution for calendar management.

Clone or Redact Events

Share your availability without sharing your personal life. When synchronizing events, you can choose to clone events with full details or redact them to show only that you are busy. This means you can keep title, description, and location information private while still letting others see your availability. This feature is particularly valuable for consultants and freelancers who need to share calendar information with clients without exposing the specifics of other engagements.

Filter by Day and Time

Each synchronization gets its own set of rules for when events should be shared. You can synchronize only weekdays, weekends, or pick specific days of the week. Set a time range to limit syncing to work hours, such as 9 AM to 6 PM only. You can also set a start date for synchronization. This granular control ensures that your personal time remains private and that only relevant events appear on your work or client calendars.

No Accounts to Link

Your Google, Microsoft, and Apple credentials stay safe under macOS Internet Accounts. There are no logins on third-party websites and no need to share passwords or grant external access to your calendar accounts. The app works directly with the calendar accounts you have already configured on your Mac, eliminating the security risks associated with linking accounts through external services.

Stays Out of the Way

Very Good Calendar Sync runs quietly in your menu bar and requires no ongoing attention. Set up your syncs once, then forget about it. The application synchronizes automatically whenever your calendars change, working silently in the background. There are no extra apps to install, no connections to configure, and no constant notifications. Your calendars are already in Calendar.app, and this app simply keeps them aligned.

Consultants Managing Client Calendars

Consultants often work with multiple clients, each with their own calendar system. Very Good Calendar Sync allows consultants to keep every client calendar in sync without manually cross-checking availability or risking double-bookings. The clone and redact features are particularly useful here, as consultants can share their availability with clients while keeping the details of other client engagements private. The app ensures that all calendars show the same real-time availability, eliminating scheduling conflicts.

Employees with Work and Personal Calendars

Professionals who maintain separate work and personal calendars can seamlessly manage both schedules without confusion. When a dentist appointment is added to a personal calendar, it automatically appears as a busy block on the work calendar. This prevents colleagues from scheduling meetings during personal commitments. The filter by day and time feature ensures that personal events only sync during appropriate hours, maintaining work-life boundaries.

Freelancers Juggling Multiple Projects

Freelancers often manage calendars for different projects or clients, each with distinct scheduling needs. Very Good Calendar Sync allows freelancers to create separate synchronization rules for each client relationship. A freelancer might choose to share full event details with one client while only showing busy time to another. The automatic background synchronization ensures that availability is always up to date across all project calendars.

Agencies and Cross-Functional Teams

Agencies and teams that balance internal and client-facing calendars can use Very Good Calendar Sync to eliminate confusion. Everyone on the team sees the same real-time availability, whether they are looking at internal schedules or client-facing calendars. This prevents the common problem of team members double-booking themselves because internal meetings are not visible on client calendars or vice versa. The on-device synchronization ensures that sensitive internal scheduling information never leaves the Mac.

Do you store any of my calendar data?

No. Very Good Calendar Sync runs entirely on your Mac and does not store or transmit any of your calendar data. The app has no servers of its own, performs no data collection, and does not run any analytics on your calendar. Your Mac talks directly to your calendars without any intermediary. This means your sensitive scheduling information, event details, and personal appointments never leave your device.

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 it shows up in your Mac's Calendar app, it works with Very Good Calendar Sync. There is no extra setup required beyond having your calendars configured in macOS Internet Accounts.

Does it sync when my Mac is off or asleep?

No. Because Very Good Calendar Sync runs entirely on your Mac, it can only synchronize your calendars when your Mac is awake and powered on. The app does not use any cloud infrastructure or remote servers that could operate independently of your device. Synchronization occurs automatically whenever your Mac is active and your calendars change.

Is this app available for Windows?

No. Very Good Calendar Sync is built specifically for macOS and works directly with macOS Calendar.app. It is not available for Windows, iOS, or any other operating system. The app takes advantage of native macOS calendar access and menu bar integration to provide its seamless synchronization experience.
