How to Block App Access to Notifications, Account Info, and Tasks

What Causes This?

Windows lets apps request access to personal and productivity data such as notifications, account info, contacts, calendar, tasks, and messaging. Over time, you may approve these permissions without noticing, especially during app setup or after installing Microsoft Store apps. Some desktop apps also use broad account access through your Microsoft account, which can expose more data than you intended.

Common Symptoms

• Apps show your account name, email address, or profile details without you expecting it
• Calendar, reminders, or task apps can read data from other apps or accounts
• Apps send or react to notifications even when you do not want them to
• Privacy settings feel inconsistent after a Windows update or new app install
• You are not sure which apps can access personal data on your PC

How to Fix It Manually

1. Open Windows Privacy settings

   • Press Windows + I to open Settings.
   • In Windows 11, go to Privacy & security.
   • In Windows 10, go to Privacy.

2. Review notification access

   • In Windows 11, open System > Notifications to control which apps can send notifications.
   • Turn off notifications for apps you do not trust or do not need.
   • If an app does not need to alert you at all, disable it completely here.

3. Block access to account info

   • In Privacy & security, scroll to App permissions and click Account info.
   • Turn off Account info access if you want to block all apps from reading your name, picture, and account details.
   • Or leave global access on and disable individual apps one by one.

4. Restrict calendar and task-related access

   • Under App permissions, open Calendar.
   • Turn off access for apps that should not read or modify your schedule.
   • If you use task or reminder apps tied to calendar data, review those carefully. Windows may not always list “Tasks” separately, so calendar-connected apps are often the place to check.

5. Check other related privacy categories

   • Review Contacts, Email, Messaging, and Notifications-related app settings where available.
   • Disable access for any app that does not need personal or productivity data to function.
   • Be especially cautious with apps you rarely use.

6. Review Microsoft account-connected apps

   • Open your browser and sign in to your Microsoft account at account.microsoft.com.
   • Check your Privacy and Apps and services permissions.
   • Remove apps or services you no longer use, especially ones connected to mail, calendar, or profile data.

7. Remove apps you do not trust

   • Press Windows + I and go to Apps > Installed apps in Windows 11 or Apps > Apps & features in Windows 10.
   • Find apps you no longer need, click the three dots or select the app, then choose Uninstall.
   • If an app keeps asking for access you do not want to grant, removing it is often the simplest fix.

8. Restart and verify

   • Restart your PC after changing permissions.
   • Open the apps you kept and confirm they still work as expected.
   • If something breaks, return to the specific permission page and re-enable only the setting that app truly needs.
