Very Good Calendar Sync

Very Good Calendar Sync is a privacy-first macOS application that automatically synchronizes your calendars across work, personal, and client accounts. It runs entirely on your Mac, using the native calendar access provided by macOS Calendar.app. No data ever leaves your machine, no third-party servers are involved, and no credentials are shared. The app is designed for consultants, freelancers, employees, and anyone juggling multiple calendars who wants to eliminate double-bookings and manual cross-checking. Its core value proposition is simple: set up your sync rules once, and the app handles everything in the background. You control exactly what gets synchronized, including specific weekdays, time ranges, and start dates. You also decide how much detail to share, either cloning full event details or redacting them to show only that you are busy. Very Good Calendar Sync works with Google Calendar, Microsoft Outlook, Apple iCloud, and any CalDAV account that appears in Calendar.app. There is no middleman, no cloud storage, and no analytics on your calendar data. The first sync is free, and paid plans start at just GBP 1.99 per month. It is built by someone who got tired of third-party apps wanting access to their entire life and decided to create a better way.

Clone or Redact

Share your availability without sharing your life. Clone events with full details for complete transparency, or redact them to show only that you are busy. Title, description, and location stay private when you choose redaction. This gives you total control over what others see in your synchronized calendars.

Stays Out of the Way

Runs quietly in your menu bar with zero daily interaction required. Set up your syncs once, then forget about it. The app automatically synchronizes your calendars whenever changes occur. No pop-ups, no reminders, no manual triggers. Just seamless, background operation that respects your workflow.

Filter by Day and Time

Synchronize only weekdays, weekends, or pick specific days of the week. Set a daily time range to limit syncing to work hours, for example 9 AM to 6 PM. Each synchronization gets its own independent rules, so you can have different settings for your work calendar versus your personal calendar.

No Accounts to Link

Your Google, Microsoft, and Apple credentials stay safe under macOS Internet Accounts. There are no logins on third-party websites, no separate account creation, and no external authentication flows. The app simply uses the calendar access your Mac already has configured. This eliminates security risks and reduces setup time to roughly two minutes.

Consultants Managing Multiple Client Calendars

Consultants often juggle three, four, or more client calendars simultaneously. Very Good Calendar Sync keeps every client calendar aligned without manually cross-checking availability or risking double-bookings. Set up a sync rule for each client, choose clone or redact mode, and let the app handle the rest. Your clients see accurate availability at all times.

Employees Balancing Work and Personal Schedules

Employees with separate work and personal calendars can seamlessly manage both without conflicts. Never get double-booked because your team could not see your dentist appointment. Configure filters to sync only work hours and weekdays, so your personal events stay private during office hours while still blocking out time when you are unavailable.

Freelancers Juggling Multiple Projects

Freelancers often maintain separate calendars for different projects or clients. Very Good Calendar Sync allows you to synchronize all of them into one master view while controlling what each client sees. Use redact mode to show only busy time for clients, keeping project details and meeting notes completely private.

Agencies and Cross-Functional Teams

Agencies need to balance internal calendars with client-facing schedules across multiple team members. Very Good Calendar Sync ensures everyone sees the same real-time availability. No confusion about who is free when, no missed meetings, and no double-bookings. The app works with any calendar provider your team already uses.

Do you store any of my calendar data?

No. Very Good Calendar Sync runs entirely on your Mac. It has no servers of its own, no data collection, and no analytics on your calendar. The app uses your Mac's native calendar access to read and write events. Nothing is transmitted externally. Your calendar data never leaves your machine.

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 Calendar.app, it works with the app. No extra setup or third-party access is required.

Does it sync when my Mac is off or asleep?

No. Synchronization only happens when your Mac is awake and running. The app monitors your calendars in the background and syncs changes as they occur. When your Mac goes to sleep or shuts down, synchronization pauses. It resumes automatically when your Mac wakes up or starts again.

Is this app available for Windows or iOS?

No. Very Good Calendar Sync is a macOS-only application. It is built directly into the macOS ecosystem and uses native calendar access that is not available on Windows or iOS. There are currently no versions planned for other operating systems.
