Is Sync2Cal safe?

Sync2Cal connects through an authorized Google or Microsoft account, or through a calendar subscription link. You do not give Sync2Cal your Google or Microsoft password.

The permissions differ by method and provider. Here is what you are authorizing and how to stop the connection.

Google Calendar account connection

Sync2Cal requests Google's calendar.app.created permission to manage calendars created by the app. That permission does not grant access to your existing personal calendars. Sync2Cal uses a dedicated calendar for the schedule you follow.

You sign in and authorize the connection on Google's screen. See Google Calendar sync.

Microsoft Outlook account connection

Microsoft's Calendars.ReadWrite permission is broader: it permits reading and writing calendars in the authorized account. It does not technically restrict access to just one app-created calendar.

Sync2Cal uses this connection to manage the calendars it creates for you, rather than copy your private appointments into Sync2Cal. The permission shown by Microsoft is broader than Google's, so it is important to distinguish what the permission allows from how Sync2Cal uses it. See Outlook sync.

ICS subscription link

With a subscription link, your calendar app fetches events from Sync2Cal. You do not grant Sync2Cal access to your Google, Microsoft, or Apple calendar account through that link.

Treat your personal subscription URL as private. Someone who has it may be able to access the feed it serves. Do not post it publicly or include it in a screenshot when asking for help.

Apple Calendar uses this method. For Google and Outlook, an account connection is recommended for direct updates, with the link method available as an alternative. Compare connection methods.

How to disconnect

For a Google or Outlook connection, use the integration controls in your Sync2Cal account settings. Disconnecting stops that provider connection and requests cleanup of its managed calendars. This affects more than a single event or calendar, so use Remove if you only want to stop one subscription.

You can also manage third-party access in your Google or Microsoft account. Revoking permission there stops access but does not guarantee deletion of events already created. For an ICS subscription, unsubscribe from the calendar in your app and remove the subscription in Sync2Cal if you no longer need it.

Payments and account information

Payments are handled through our payment provider. For details about account information and its use, read our privacy policy. Removing a calendar or disconnecting an integration does not cancel a paid plan; see billing cancellation.

If a permission prompt does not match what you expected, stop and email hello@sync2cal.com with the wording, without sharing passwords, authorization codes, or private feed URLs.
