Very Good Calendar Sync

Very Good Calendar Sync is a macOS application designed to solve the persistent problem of managing multiple calendars across work, personal, and client accounts. The app runs entirely on your Mac and synchronizes calendars that are 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 you to link accounts, share credentials, or expose sensitive data to third-party servers. The app operates quietly from your menu bar, monitoring your calendars and syncing changes in the background as they happen. You set up your synchronization rules once and the app handles everything automatically from that point forward. This makes it ideal for consultants managing client calendars, employees balancing work and personal schedules, freelancers juggling multiple projects, or anyone tired of calendar chaos. What sets Very Good Calendar Sync apart is its commitment to privacy and security. 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. This on-device approach ensures that your sensitive scheduling information remains under your control at all times.

Clone or Redact Events

Share your availability without sharing your life. When synchronizing events, you can choose to clone them with full details or redact them to show only that you are busy. This means you can keep event titles, descriptions, and locations completely private while still maintaining accurate availability across your calendars. This feature is particularly valuable for professionals who need to show clients or colleagues when they are free without revealing the nature of their other commitments.

Filter by Day and Time

Gain precise control over what gets synchronized by setting specific rules for each synchronization. You can choose to synchronize only weekdays, weekends, or pick specific days of the week. Additionally, you can set a time range to limit syncing to work hours only, such as 9 AM to 6 PM. Each synchronization gets its own set of rules, allowing you to customize exactly how and when your calendars stay aligned. You can also set a start date for synchronization to begin.

Stays Out of the Way

The app runs quietly in your menu bar and requires minimal attention after initial setup. You configure your syncs once, then forget about them. Synchronization happens automatically whenever your calendars change, so you never need to manually update or refresh anything. The app monitors your calendars and syncs changes in the background without interrupting your workflow or demanding your attention.

No Accounts to Link

Your Google, Microsoft, and Apple credentials stay safe under macOS Internet Accounts. There are no logins on third-party websites or external services required. The app works directly with the calendars already configured on your Mac, using your Mac's native calendar access. This eliminates the security risks associated with sharing account credentials or granting third-party applications access to your calendar data.

Consultants Managing Client Calendars

Consultants often work with multiple clients, each with their own calendar system. Very Good Calendar Sync allows you to keep every client calendar synchronized without manually cross-checking availability or risking double-bookings. You can set different synchronization rules for each client, controlling what information is shared and when. This ensures your availability is always accurate across all client calendars while keeping sensitive information private.

Employees Balancing Work and Personal Schedules

Employees with separate work and personal calendars can seamlessly manage both schedules without confusion. When a new meeting appears on your work calendar, it automatically appears on your personal calendar. This prevents double-bookings because your team can see your dentist appointment or personal commitments. You control exactly what gets shared, so you can choose to show only that you are busy rather than revealing personal details.

Freelancers Juggling Multiple Projects

Freelancers often maintain separate calendars for different projects or clients. Very Good Calendar Sync enables you to synchronize availability across all these calendars while maintaining privacy. You can set different rules for each synchronization, such as only sharing weekdays during business hours. This keeps your schedule honest and up to date across all projects without requiring you to manually update each calendar.

Agencies and Cross-Functional Teams

Agencies and teams that work across internal and client-facing calendars benefit from real-time availability synchronization. Everyone sees the same accurate availability, eliminating confusion and double-bookings. Team members can see when colleagues are free without needing access to their full calendar details. This streamlines scheduling across the organization and ensures that client meetings and internal commitments are properly balanced.

Do you store any of my calendar data?

No. Very Good Calendar Sync runs entirely on your Mac and does not store or transmit your calendar data anywhere. The app uses your Mac's native calendar access to read and write calendar events locally. No data is sent to external servers, no analytics are collected, and no third-party services have access to your calendar information. Your data never leaves 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. No extra setup or third-party access is required.

Does it sync when my Mac is off or asleep?

No. Because the app runs entirely on your Mac, synchronization only occurs when your Mac is awake and running. When your Mac is off or asleep, the app cannot monitor or sync your calendars. However, once your Mac wakes up, the app will detect any changes that occurred while it was asleep and synchronize them automatically.

Is this app available for Windows or iOS?

Very Good Calendar Sync is currently available only for macOS. The app is built specifically to work with macOS Calendar.app and takes advantage of native macOS features. There are no versions available for Windows or iOS at this time. If you need cross-platform synchronization, you would need to use macOS as your primary device for running the app.
