MASVS-STORAGE: Storage

Mobile applications handle a wide variety of sensitive data, such as personally identifiable information (PII), cryptographic material, secrets, and API keys, that often need to be stored locally. This sensitive data may be stored in private locations, such as the app's internal storage, or in public folders that are accessible by the user or other apps installed on the device. However, sensitive data can also be unintentionally stored or exposed to publicly accessible locations, typically as a side-effect of using certain APIs or system capabilities such as backups or logs.

This category is designed to help developers ensure that any sensitive data intentionally stored by the app is properly protected, regardless of the target location. It also covers unintentional leaks that can occur due to improper use of APIs or system capabilities.
