Java Code Privacy Helper

About

Java Code Privacy Helper is a local browser extension for reversible Java identifier obfuscation before sharing code snippets with AI chat tools.

The extension helps developers ask AI assistants about Java code while reducing exposure of project-specific names such as classes, services, methods, fields, parameters, local variables, DTOs, and domain-specific identifiers.

Typical workflow:

1. Paste a Java code snippet into the extension.
2. Click “Obfuscate”.
3. Copy the obfuscated version and send it to an AI chat.
4. Paste the AI response back into the extension.
5. Click “De-obfuscate”.
6. The extension restores the original identifier names using the locally stored mapping.

Example use case:

Before sharing code with an AI assistant, you may want to replace names like:

- PaymentGatewayService
- createExternalAccessUser
- currentUserService
- integrationCount
- UserRegistrationRequest

with neutral placeholders such as:

- JCPH_T_001
- JCPH_m_001
- JCPH_f_001
- JCPH_v_001
- JCPH_T_002

After receiving the AI response, the extension can replace the placeholders back with the original names.

- No remote backend in this build
- No payments or subscriptions in this build
- No analytics
- No advertising
- No account required

The extension stores settings and reversible mappings locally in Chrome extension storage. It does not upload Java code snippets, generated mappings, or settings to any external server.

Important limitation:

Java Code Privacy Helper is designed for code snippets and AI-chat workflows. It is not a full Java compiler, IDE refactoring engine, or production-grade source-code obfuscator. Complex multi-file projects, reflection-heavy frameworks, generated code, unusual formatting, or framework-specific naming conventions may require manual review.

The extension is intended as a developer productivity and privacy helper for AI prompts, not as a security boundary for protecting proprietary source code.
