Synchronization moves local information to other devices and cloud services. Revisit assumptions that data stays on one phone.
Evaluation approach
Document synchronized records, account changes and deletion. Define recovery relationships between local keys and cloud data.
Application example
A notes app may offer device-only storage for private documents. Consider copies created before synchronization was disabled.
Limits and considerations
Platform encryption does not resolve the application's access model or minimization choices.
Explaining deletion status
Local, cloud and other-device copies may have different states. Distinguish completed deletion from pending synchronization. Test that an older device does not restore deleted records when reconnecting.
Checks and decisions
- Inventory synchronized fields
- Test account transitions
- Document deletion
