Storage location determines which applications and user actions can reach data. Scoped storage is part of that access model.
Evaluation approach
Private files, shared media and user-selected documents have different lifecycles. Directory names alone do not protect secrets.
Application example
Cache invoices privately, but make clear that an exported copy is now shared data.
Limits and considerations
Uninstallation and clearing application data do not affect every storage type identically.
Is an exported file still protected?
A copy placed in shared storage has a different boundary from the private original. Provide clear information and reauthentication where appropriate before export. Do not claim that deleting the in-app copy removes every external copy.
Checks and decisions
- Document data locations
- Separate export behavior
- Measure cleanup
