Power apps

Hi @Duarte Nuno Semedo Leite

Based on your description, I understand you are creating a Canvas app in Power Apps and want to know what happens to the information entered by users since you haven't connected any background database or data source.

If your Power Apps application does not connect to any data source and you have not explicitly configured local storage logic, the information entered by users is completely temporary and will be deleted once they close the session. It is not stored anywhere automatically by Microsoft.

In Power Apps, canvas apps are designed to act as user interfaces that pass data back and forth to external data sources (like Dataverse, SharePoint, SQL Server, or Excel on OneDrive). If no data source is connected:

• Any information typed into controls, inputs, internal variables, or Collections only exists in the active memory of the application during that specific session.
• Collections are strictly local to the app instance; they are isolated to that specific user and device and are never shared across other users.
• Once the user closes the app or refreshes the browser, that memory is completely wiped out and the data is lost.

There are only a couple of scenarios where data might stay on a device without a cloud data source, which you would have to manually code:

• SaveData() and LoadData() Functions: If you are explicitly using these functions in your code, Power Apps will save the collection data locally into the secure storage zone of the user's physical device or browser cache.
• Dataverse Offline Capability: If offline capability is enabled, the device caches data locally, but this requires an active Dataverse structure.

Therefore, if your app does not connect to an external data source and you are not using local SaveData() / offline caching logic, the entered information will not persist after the user closes the app.

Please refer to the official Microsoft documentation:

SaveData, LoadData, and ClearData functions

I hope this gives you peace of mind regarding how your app handles data.
