Privacy, Data Management, and Troubleshooting

Browser-Based Processing

The supplied implementation processes text through JavaScript functions and browser-compatible libraries.

Supported operations include:

Code minification and formatting
HTML and CSS validation
HTML and JavaScript security scanning
JSON processing
Base64 and URL encoding
Regular expression matching
Text comparison
UUID generation
Color conversion
Text analysis

Some supporting libraries are loaded through external content delivery networks.

Privacy Considerations

Client-side processing can reduce the need to send entered text to a server for processing.

However, the supplied JavaScript alone does not establish the complete privacy behavior of the deployed application.

Other resources, hosting infrastructure, analytics, and browser activity may generate network requests.

Do not assume that all input is confidential without verifying the deployed application's full behavior.

Purge Data

WebZone provides a Purge data control to attempt removal of local application data.

Usage

Locate Purge data.
Click the button.
Confirm the action.
Allow the browser to complete the cleanup and reload.

Keyboard Shortcut

Ctrl + Alt + Backspace

The shortcut triggers the same confirmation workflow.

Data Targeted by Purge

Data Type	Action
Input fields	Clear values
Output viewers	Clear displayed content
Select controls	Reset selections
Clipboard	Attempt to replace text with an empty string
localStorage	Clear local storage
sessionStorage	Clear session storage
IndexedDB	Attempt to delete accessible databases
Cache Storage	Delete accessible caches
Service Workers	Attempt to unregister registrations
Cookies	Attempt to expire accessible cookies
Object URLs	Revoke tracked object URLs

The purge operation then attempts to reset the tool selector and reload the application.

Limitations

The purge action cannot guarantee deletion of all browser or server-side information.

Important limitations include:

HTTP-only cookies cannot be deleted directly by JavaScript.
Browser permissions may prevent clipboard modification.
IndexedDB deletion may be blocked by active connections.
Downloaded files remain on the user's device.
Browser history is not cleared.
Server-side logs and data, if any, are not deleted.
Information outside the current origin is not cleared.

The operation should be understood as a best-effort local cleanup mechanism.

Troubleshooting

JavaScript Minification Fails

Possible causes:

Invalid JavaScript
Unsupported syntax
Terser failed to load
A processing error occurred

Suggested actions:

Check the input syntax.
Reduce the input to a smaller test case.
Reload the application.
Verify that external scripts are not blocked.

HTML Minification Fails

The HTML minifier depends on its required JavaScript library being present.

If the library is unavailable, the tool may report that HTML minification could not run.

Verify that required resources load successfully.

CSS Minification Fails

Check that CSSO is available and that the supplied stylesheet is valid.

If optional keyframe purging produces unexpected results, disable it and try again.

Beautification Fails

Check the input syntax and confirm that Prettier and its required parser plugins have loaded.

Validation Reports Unexpected Issues

HTML and CSS validation depends on configured rules and library definitions.

Some newer or nonstandard constructs may not be recognized.

Review the reported rule before changing valid application code.

Security Scan Produces Many Findings

The scanner performs heuristic pattern detection.

Some findings may be false positives or context-dependent.

Review each finding individually and verify whether the reported pattern introduces an actual risk.

JSON Operations Fail

Confirm that the input is valid JSON.

Common problems include:

Trailing commas
Unquoted property names
Single-quoted strings
Comments
Incomplete objects or arrays

URL Decoding Fails

The decoder requires valid percent-encoded input.

Malformed escape sequences can cause an error.

Base64 Decoding Fails

Confirm that the input contains valid Base64 text and represents valid UTF-8.

Regular Expressions Are Slow

Certain patterns can require substantial processing time.

Simplify complex patterns or reduce the sample text.

Diff Processing Is Slow

Large text comparisons may consume significant CPU and memory.

Try smaller inputs or line-based comparison where appropriate.

Copying Results Fails

Clipboard access may be restricted by browser permissions or security settings.

Use the Download action when available.

UUID Format Is Unexpected

The supplied UUID functions contain a formatting issue that appears to remove the first hexadecimal character.

Check the generated output format before integrating UUIDs into other applications.

Responsible Usage

WebZone is a collection of development and inspection utilities.

For production workflows:

Validate input before processing.
Review generated output.
Test optimized code.
Treat security findings as preliminary.
Verify privacy requirements before entering confidential material.
Keep independent backups of important files.

Support and Feedback

When reporting a problem, include the name of the affected tool, browser information, the selected options, and a reproducible example that does not contain private or sensitive information.
