Very Good Calendar Sync

Very Good Calendar Sync is a macOS application designed to eliminate the chaos of managing multiple calendars across work, personal, and client accounts. Unlike cloud-based synchronization services that require sharing credentials or granting third-party access to your sensitive data, this app operates entirely on your Mac. It directly integrates with macOS Calendar.app, allowing you to synchronize any calendar that appears there, including Google Calendar, Microsoft Outlook, Apple iCloud, and any CalDAV account. The core value proposition is simple: set up your synchronization rules once, and the app automatically keeps your calendars aligned in the background without any further intervention. This tool is ideal for consultants managing multiple client calendars, employees balancing work and personal schedules, freelancers juggling various projects, and anyone tired of double-bookings and manual cross-checking. The app prioritizes privacy above all else. Your calendar data never leaves your Mac. There are no servers owned by the developer, no data collection, no analytics tracking your events, and no third-party access. The app uses your Mac's native calendar access to read and write events, ensuring that your sensitive information remains under your control. With flexible filtering options, you can choose exactly what gets synchronized and when, giving you complete control over your availability. The first synchronization between two calendars is free, and paid plans offer unlimited synchronizations with all calendar providers and email support.

Clone or Redact Events

Share your availability without sharing your personal life. When synchronizing events, you have the choice 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 preventing double-bookings. This feature is essential for professionals who need to show blocked time on a shared calendar without revealing confidential project names or personal appointments.

Stays Out of the Way

Very Good Calendar Sync runs quietly in your Mac's menu bar, requiring no ongoing attention. You set up your synchronization rules once, and the app handles the rest automatically. It continuously monitors your calendars for changes and synchronizes them in the background. New meetings added to your work calendar appear on your personal calendar without any manual action. This hands-off approach saves time and eliminates the risk of forgetting to update multiple calendars.

Filter by Day and Time

Gain granular control over when synchronization occurs. You can configure each synchronization with its own set of rules, including selecting specific weekdays to sync (such as only workdays while skipping weekends), setting daily hours (for example, only events between 9 AM and 6 PM), and choosing a start date for synchronization. This ensures that only relevant events are copied between calendars, keeping your schedules clean and focused on what matters.

No Accounts to Link

Your credentials remain completely safe within macOS' Internet Accounts system. There is no need to log in to any third-party websites or grant access to external services. The app simply works with the calendar accounts you have already configured on your Mac. This approach eliminates the security risks associated with sharing passwords or API tokens and simplifies the setup process to just a few clicks.

Consultants Managing Client Calendars

Consultants often work with multiple clients, each maintaining their own calendar system. Manually cross-checking availability across these calendars is time-consuming and prone to errors. With Very Good Calendar Sync, a consultant can synchronize each client's calendar with their primary work calendar. They can set specific rules to only sync business hours and redact event details to protect client confidentiality. The result is a single, accurate view of availability that prevents double-bookings and saves hours of administrative work each week.

Employees Balancing Work and Personal Schedules

Professionals who use separate calendars for work and personal life frequently face scheduling conflicts. A dentist appointment or personal errand can accidentally overlap with a critical team meeting. By synchronizing their work and personal calendars, employees can ensure that both sides see accurate availability. They can choose to only show busy time on their work calendar for personal events, keeping the details private. This eliminates the need to manually block time or send separate notifications to colleagues about personal commitments.

Freelancers Juggling Multiple Projects

Freelancers often manage calendars for different clients, each with its own set of deadlines and meetings. Keeping track of all these commitments without double-booking is a significant challenge. Very Good Calendar Sync allows freelancers to synchronize all their client calendars into a single master calendar. They can filter by specific days and times relevant to each project and clone event details for work-related items while redacting personal blocks. This unified view ensures they never miss a client meeting or overcommit their time.

Agencies and Cross-Functional Teams

Agencies frequently need to balance internal team calendars with client-facing schedules. Confusion arises when internal meetings are not visible to clients or vice versa. With this app, agencies can synchronize internal calendars with client calendars, ensuring everyone sees the same real-time availability. Team members can see when colleagues are busy with client work, and clients can see when their account team is available for calls. This transparency reduces scheduling friction and improves collaboration across the entire organization.

Do you store any of my calendar data?

No. Very Good Calendar Sync operates entirely on your Mac. The app does not have its own servers, does not collect any data, and does not transmit your calendar information anywhere. It uses your Mac's native calendar access to read and write events directly. Your data remains under your control at all times, and no third party, including the developer, has access to your calendar contents.

Which calendar providers are supported?

The app supports 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 it in your Mac's Calendar app, Very Good Calendar Sync can work with it. There is no need for additional configuration or third-party access beyond what you have already set up on your Mac.

Does it sync when my Mac is off or asleep?

No. Since the app runs entirely on your Mac, it requires your computer to be powered on and awake to perform synchronizations. When your Mac is off or asleep, the app cannot monitor for changes or update your calendars. Synchronization will resume automatically once your Mac is awake 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 designed to integrate deeply with macOS Calendar.app and the operating system's native calendar access. There is no version for Windows or iOS at this time. The developer focuses on providing the best possible experience for Mac users who need reliable, private calendar synchronization.

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. When you are ready for more, you can choose from the following plans:

Monthly Plan: GBP 1.99 per month. This flexible month-to-month option allows you to cancel anytime.
