How to remove local storage data after uninstallation of the teams custom tab app from teams store

Question

I made an teams custom tab application which stores data in local storage But it stores the data even after uninstalling the application. So is there any way to remove that local storage data after uninstalling the application from the Teams app store.

Answer 1

@Raghavendra Reddy - When a custom Teams tab application stores data in local storage, it will persist even after the application is uninstalled from the Teams app store. Unfortunately, there is no built-in mechanism in Teams to automatically clear local storage when an app is uninstalled. However, you can implement some strategies to handle this scenario.

Possible Solutions:

1. Use Session Storage Instead of Local Storage:
   • Session storage is cleared automatically when the page session ends. This means the data will not persist after the user closes the browser tab or window.
   • Drawback: This approach may not be suitable if you need the data to persist across sessions.
2. Implement a Cleanup Mechanism:
   • Implement a mechanism within your app to clear local storage data manually when the app is no longer needed.
   • You could trigger this mechanism when the user logs out or when you detect that the app is being uninstalled.
3. Store Data Externally:
   • Store the data on a remote server rather than in local storage. This way, you can manage the data lifecycle on the server-side, including purging data when the app is uninstalled.
   • Drawback: This approach might require additional infrastructure and security considerations.
