How To Block Apps to Access Your Calendar on Windows 10

Windows 10 is known for its range of useful apps, however, these apps need access to certain features like Camera, Microphone, Location, Contacts, Phone calls, Email, etc. to function properly. Calendar is also one such feature that certain apps like People, Mails or the Cortana needs access to. Therefore, these apps have access to the Calendar and its events by-default. The Calendar then makes use of the contact list to schedule emails and appointments, and then displays the day’s appointment to you.

However, sometimes the access to the Calendar may be not necessary, but the apps would still keep asking for permission. So, if you think that you do not need the apps to access your calendar on Windows 10, you can  disable the access to keep your calendar and events private from the apps. Here are a few methods using which you can block apps to access your calendar.

 

Method 1: Turn Off App Access to Calendar Through the Settings App

 

This method will help you to prevent apps to access calendar when you think it’s not required. You can also turn on or turn off the access only for individual apps like Cortana, Mail and Calendar or People, or for all of them. You can also disable the access to calendar for a 3rd party application if listed in the settings window. Let’s see how to turn off app access to calendar:

 

Step 1: Go to Start, click on it and click on the gear icon to launch the Settings app.

 

Start Right Click Settings

 

Step 2: In the Settings window, click on Privacy.

Step 3: In the next window, go to the left side, scroll down and App permissions section, click on Calendar.

Step 4: Now, go to the right side of the pane and under the Allow apps to access calendar section, turn the slider to the left to turn it off.

This will disable the access to calendar for all apps.

Step 5: If you want to disable access to calendar for specific apps, go to the Choose which apps can access your Calendar section and turn off access to calendar for the app you don’t want to.

This will disable access to calendar for only individual apps as chose by you.

Step 8: In the Windows Powershell (admin) window, execute the below command to get the package name for the specific app:

 

Get-AppxPackage -AllUsers | Select Name, PackageFullName

 

Windows Powershell Run Get Appxpackage Command Enter

 

Step 9: Now, note down the name of the app from the Name section.

For instance, we want to disable calendar access for the Microsoft People app, so the app Name is Microsoft. People.

 

Get Appxpackage Name Note Down The App Name

 

Step 10: Now, type the below command and hit Enter:

 

Get-AppxPackage -Name "Microsoft.People"

 

Note down the PackageFamilyName of the app.

 

*Note: Here, replace the “Microsoft.People” (app name ) with the name of the app you want to block for calendar access.

Method 3: Turn Off App Access to Calendar Through Registry Editor

 

If you were able to follow the Local Group Policy Editor, it will automatically add the specific settings in the Registry. However, if you do not have access to the Local Group Policy Editor in your Windows 10 version, then you can directly modify the settings in the Registry Editor. For this, you would need to add the required keys and the value on your own.

*Note – Each option has different values, so if you need only an individual value for example, if you just want the value to be “force deny” for all apps, then you must add only that value and not any other value.

Let’s see how to edit the Registry:

 

Step 1: Right-click on Start menu and select Run to open the Run command box.

 

Start Right Click Run

 

Step 2: Type regedit in the Run command search box and press OK to open the Registry Editor window.

 

Run Command Regedit Ok

 

Step 3: In the Registry Editor window, navigate to the below path to reach the AppPrivacy key:

 

HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\AppPrivacy

 

*Note – If the AppPrivacy key is missing, then follow the below steps to add the key:

 

1: Right-click on the Windows folder, select New and then select Key.

Step 7: If you want to change the value to 2 (force deny) for all the options of the Local Group Policy Editor, you will need to create the three different values.

For this, go to the right side of the window, right-click on an empty area and select New > Multi-String Value.
