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 entirely on your Mac, sitting quietly in your menu bar, and automatically synchronises events between any calendars available in macOS Calendar.app, including Google Calendar, Microsoft Outlook/Exchange, Apple iCloud, and any CalDAV account. The core value proposition is simple: set up your synchronisation rules once, and the app handles the rest in the background, ensuring your availability is always accurate across work, personal, and client calendars. The product is built for consultants managing client calendars, employees balancing work and personal schedules, freelancers juggling multiple projects, and teams that need real-time visibility into each other's availability. What sets Very Good Calendar Sync apart is its unwavering commitment to privacy. Your calendar data never leaves your Mac. There are no credentials to share, no third-party access, no cloud storage, and no analytics on your calendar data. The app uses your Mac's native calendar access, meaning nothing is transmitted externally. This on-device approach means your sensitive meeting details, client names, and personal appointments remain completely under your control. The app offers flexible synchronisation options, including the ability to clone events with full details or redact them to show only that you are busy, keeping your title, description, and location private. With a free tier for a single synchronisation and affordable paid plans for unlimited use, Very Good Calendar Sync provides a practical, privacy-first solution for anyone tired of double-bookings and manual calendar management.

Clone or Redact

Share your availability without sharing your life. When synchronising events, you have full control over what information is shared. You can clone events with full details, meaning the title, description, location, and all other information are copied to the destination calendar. Alternatively, you can redact events to show only that you are busy during that time block, keeping the event title, description, and location completely private. This is ideal for situations where you need to block out time for a confidential client meeting or a personal appointment without revealing any specifics. The choice is per synchronisation, giving you granular control over what each calendar's audience can see.

Stays Out of the Way

Very Good Calendar Sync is designed to be unobtrusive. It runs quietly in your Mac's menu bar, consuming minimal system resources. You set up your synchronisation rules once, defining which calendars to sync, what days and times to include, and whether to clone or redact events. After that initial setup, the app works automatically in the background, monitoring your calendars for changes and synchronising them whenever an event is created, modified, or deleted. There is no need to manually trigger syncs or check for updates. The app simply does its job, allowing you to focus on your work without constant interruptions or reminders.

Filter by Day and Time

Each synchronisation you create can have its own set of rules regarding when events should be copied. You can choose to synchronise only on specific weekdays, such as Monday through Friday, and skip weekends entirely. You can also set a daily time range, for example, only syncing events that fall between 9 AM and 6 PM. Additionally, you can set a start date for synchronisation, meaning events before that date will not be copied. This level of filtering ensures that only the most relevant events are shared between calendars, preventing your personal calendar from being cluttered with work events that happen outside your working hours, and vice versa.

No Accounts to Link

Your calendar credentials remain completely secure. Very Good Calendar Sync does not require you to log into any third-party website or share your Google, Microsoft, or Apple credentials with the app itself. Instead, it leverages your Mac's existing Internet Accounts system, which is the same secure mechanism used by macOS Calendar.app. This means your credentials stay within Apple's secure environment, and the app simply accesses your calendars through the native APIs. There are no logins to remember, no passwords to store, and no risk of your credentials being compromised through a third-party service. This is a fundamental part of the product's privacy-first design.

Consultants Managing Client Calendars

Consultants often work with multiple clients, each with their own calendar system. Manually checking each client's calendar for availability before scheduling a meeting is time-consuming and prone to errors. With Very Good Calendar Sync, a consultant can synchronise each client's calendar to a master calendar, using the redact feature to show only busy time blocks without revealing client names or meeting details. This creates a single, accurate view of availability across all clients. The app automatically updates the master calendar whenever a client adds or changes a meeting, eliminating double-bookings and ensuring the consultant always knows when they are free to take on new work.

Employees Balancing Work and Personal Schedules

Professionals who maintain separate work and personal calendars often struggle with scheduling conflicts. A dentist appointment on a personal calendar can lead to a double-booking if a colleague schedules a meeting during that time. Very Good Calendar Sync solves this by synchronising personal events to the work calendar as private, redacted busy blocks. The employee's team sees that time is blocked without knowing the reason. Conversely, important work meetings can be cloned to the personal calendar with full details, ensuring the employee never misses a critical meeting while managing personal errands. This creates a seamless, conflict-free schedule.

Freelancers Juggling Multiple Projects

Freelancers frequently work with multiple clients simultaneously, each expecting dedicated time and attention. Without a centralised view, it is easy to accidentally overcommit or miss a deadline. Very Good Calendar Sync allows freelancers to create a single master calendar that aggregates events from all client calendars. By cloning events with full details, the freelancer can see all project meetings, deadlines, and calls in one place. The app's background synchronisation ensures that any last-minute changes from a client are immediately reflected, allowing the freelancer to adjust their schedule proactively and maintain a professional reputation for reliability.

Agencies and Cross-Functional Teams

Agencies managing both internal operations and client-facing projects face a unique challenge: balancing internal meetings with client work. Very Good Calendar Sync enables agencies to synchronise internal team calendars with client project calendars. For example, an internal status meeting can be cloned to a client-facing calendar as a redacted busy block, showing the client that the team is occupied without revealing internal strategy discussions. Similarly, client meetings can be cloned to internal calendars with full details, ensuring the entire team is aware of client commitments. This maintains transparency with clients while protecting internal workflows.

Do you store any of my calendar data?

No. Very Good Calendar Sync runs entirely on your Mac and does not transmit any of your calendar data to external servers. The app has no servers of its own, does not collect data, and does not run analytics on your calendar. All synchronisation happens directly between your Mac and your calendar providers using your Mac's native calendar access. Your credentials, event titles, descriptions, locations, and attendee information never leave your device. This is a core design principle of the product.

Which calendar providers are supported?

Very Good Calendar Sync works with any calendar that is available 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 your Mac's Calendar.app, you can use it with Very Good Calendar Sync. There is no need for additional setup or third-party connections. Simply add your calendars to your Mac using the Internet Accounts system, and the app can access them.

Does it sync when my Mac is off or asleep?

No. Because Very Good Calendar Sync runs entirely on your Mac, it cannot synchronise calendars when your Mac is powered off or in sleep mode. The app monitors your calendars in the background while your Mac is awake and connected to the internet. When you wake your Mac or turn it on, the app will automatically detect any changes that occurred while it was unavailable and synchronise them. For real-time synchronisation, your Mac needs to be powered on and connected to the internet.

Is this app available for Windows or iOS?

Currently, Very Good Calendar Sync is only available for macOS. It is built as a native macOS application that integrates directly with the operating system's Calendar.app and Internet Accounts. There is no Windows version or iOS version available at this time. The app is designed to be a companion for Mac users who need to manage multiple calendars from their desktop. For iOS users, you would need to rely on your calendar provider's native synchronisation features or look for other solutions.

Very Good Calendar Sync offers a free tier and three paid plans to suit different needs and budgets. A single synchronisation between two calendars is completely free with no payment required. When you need more synchronisations, you can choose from the following plans:

Monthly: GBP 1.99 per month. This is a flexible month-to-month subscription that you can cancel at any time.

Annual: GBP 19.99 per year. This is the best value plan, saving you over 15 percent compared to the monthly plan.

Lifetime: GBP 39.99 one-time payment. This is a single payment that gives you the app forever, including all future updates.

All paid plans include unlimited synchronisations, support for all calendar providers, and email support. The license is per user and covers all of your Macs. You can download the app for free and choose your plan within the application.
