Contacts Sync
Contacts Sync is a macOS app that syncs Google contacts with Mac contact accounts and helps keep address books consistent across devices.
What is Contacts Sync?
Contacts Sync is a productivity app for macOS that helps users sync Google contacts with the Contacts data stored on a Mac. It is designed for people who keep contacts in multiple places and want updates made in one location to carry over to the other without manual re-entry. The app supports two-way sync as well as one-way and manual sync options, which makes it useful for both ongoing maintenance and controlled transfers. It can work with different Mac contact accounts, including local and cloud-backed address books, and it supports detailed contact fields such as names, phone numbers, email addresses, addresses, notes, photos, and custom fields. Users can also review changes before syncing, apply filters to limit which contacts are included, and monitor recent sync activity. Contacts Sync is published by Playa Apps.

Safety overview
Status: Mostly safe
This app needs access to your contacts to do its job, so contact permission requests are expected. Because it reads and writes address book data, incorrect sync settings can merge, overwrite, or duplicate contact details if you sync the wrong accounts or direction. Review the sync mode and any pending changes carefully before applying a large sync, especially if your contact lists differ significantly.
Recommendation: Keep Contacts Sync if you actively use it to maintain the same contacts across Google and your Mac accounts. If you no longer sync contacts with it, you can remove it, but do so only after confirming your contact data is already correct in the accounts you rely on.
