How Wharx protects your data

Wharx runs entirely in your browser. When you paste text into the Original panel, that text is processed locally using JavaScript running on your device. It is never transmitted to Wharx servers.

The secret map — the mapping between placeholders and original values — is stored only in your browser session memory. It is never sent anywhere.

This is not a marketing claim. It is a structural property of how the application works.

By default, Wharx does not store:

• Your source text or original prompt content
• Your protected prompt text
• The placeholder-to-value mapping (your secret map)
• AI responses you paste back into Wharx
• Restored output text
• Any identifiable document content

To understand how the product is used and improve it, Wharx may collect anonymous, aggregated usage data. This includes:

• Page views
• Button clicks (e.g., Protect, Restore, Copy)
• Anonymous usage counts
• Detection category counts (not the values themselves)

Wharx does not collect prompt content, original values, restored output, or placeholder maps — not even in anonymized form.

When you protect a prompt, Wharx generates a secret map: a dictionary that links each placeholder (like [PERSON_1]) to the original value it replaced.

This secret map lives only in your browser session memory. It is not written to disk, not synced to a server, and not accessible to any third party.

When you clear your session or close the tab, the secret map is gone.

Clicking “Clear session” in the Wharx app immediately erases all in-memory state: your original text, your secret map, your protected prompt, and any AI response you pasted back.

There is no recovery path. The data does not exist anywhere else.

Wharx is a tool to help reduce the risk of sensitive data reaching AI systems. It is not a compliance guarantee, not a certified data protection product, and not a substitute for legal or regulatory advice specific to your situation.

Detection is probabilistic. Some sensitive values may not be detected. Always review the detection results before protecting a prompt.
