SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Insecure local data storage can expose credentials, tokens, and PII when apps write secrets to plain files, preferences, SQLite databases, or web storage without encryption.

Core Features & Use Cases

  • Detects and flags cleartext storage patterns in code across mobile, desktop, and web platforms.
  • Recommends platform-backed secure storage such as Keychain, EncryptedSharedPreferences, or macOS Keychain, with encryption at rest.
  • Provides remediation steps and verification guidance to ensure secrets are never stored in plain files or unprotected stores.

Quick Start

Replace any plain-text credentials in your code with platform-secure storage and verify that no secrets remain in plain text.

FAQPage Schema
How do I detect insecure local data storage exposing credentials and PII?

To detect insecure local data storage, scan mobile, desktop, and web codebases for plain-text storage patterns in files, preferences, SQLite databases, and web storage where credentials, tokens, and PII are written without encryption.

What is the best way to secure local storage for sensitive tokens?

The best way to secure local storage is replacing plain-text credentials with platform-backed secure storage such as Keychain or EncryptedSharedPreferences, ensuring encryption at rest for all sensitive tokens and PII across mobile, desktop, and web platforms.

Does this insecure storage detection work for mobile, desktop, and web codebases?

Yes, insecure local data storage detection applies across mobile, desktop, and web codebases during development, code reviews, and security audits, flagging cleartext storage patterns in platform-specific files, preferences, databases, and web storage.

How do I remediate plain-text storage patterns flagged during a security audit?

To remediate plain-text storage patterns, replace unencrypted credentials with platform-secure storage like Keychain or EncryptedSharedPreferences, apply encryption at rest, and follow verification guidance to ensure no secrets remain in unprotected stores.

What insecure local storage patterns expose credentials in plain text?

Insecure local storage patterns that expose credentials include writing secrets, tokens, and PII as cleartext to plain files, preferences, SQLite databases, or web storage without applying encryption at rest or using platform-secure storage mechanisms.
