Google Calendar is an invaluable tool for managing your schedule effectively. Its ability to integrate with other applications within the Google ecosystem, as well as with various third-party apps, enhances its versatility. However, Google has the capability to restrict access to its API, which is crucial for third-party integrations.

To facilitate integration, Google provides the Calendar Provider API. This allows external services to interact with Google Calendar, enabling them to view, create, and delete calendar events. For instance, if you utilize a work platform designed for task management, it can sync with your Google Calendar to create events, helping you and your team stay organized.

Nonetheless, granting third-party applications access to your calendar data can raise security concerns. There is always a risk that some companies may misuse this access to collect private information. Therefore, the Calendar Provider API should ideally be used by reliable and trustworthy companies.

As it stands, any app that supports the API could potentially view your calendar data without your explicit consent. To address this issue, Google is developing a feature that allows users to block specific applications from accessing the Calendar Provider API. This means that even if an app is compatible with the API, it will be prevented from accessing your data, giving you greater control over your information.

When you launch the Google Calendar app, a pop-up will inform you that your calendar data is currently accessible to other applications. From there, you can navigate to Calendar settings to manage data-sharing preferences. A toggle will allow you to block access, although it is important to note that disabling this option may not affect all applications.

This new feature is gradually being rolled out, and users are encouraged to update their Google Calendar app to access these controls promptly.
