Room organizes data access; it does not automatically encrypt the database. Assess why each sensitive field must be stored.
Evaluation approach
Minimize local personal data. Where encryption is required, design key lifecycle, backups and logout cleanup together.
Application example
Cache a limited order summary rather than complete history, and ensure account changes never expose the previous user's rows.
Limits and considerations
An ORM does not replace authorization or safe query design.
Where should encryption decisions begin?
Ask whether the data needs to be on the device at all. Fetching it securely when needed may be simpler than encrypting a whole database. If offline storage is necessary, plan key recovery and account deletion together.
Checks and decisions
- Reduce stored fields
- Test account switching
- Review backups
