PromptShield — Privacy Policy

Last updated: April 19, 2026

This policy describes how the PromptShield — AI Chat Protector Chrome extension (“PromptShield”, “the extension”) handles information when you use it.

Summary

What the extension does

On supported AI chat websites, PromptShield can read the text you are about to send (for example, when you press Enter or use a send control) so it can warn you if it looks like sensitive information (such as certain ID formats, payment-related patterns, secrets, or similar). Processing is done locally to show you a warning or optional redaction before send.

Data stored on your device

Settings such as on/off, optional developer mode, per-site preferences, and related options are stored using chrome.storage.sync, which is managed by Google Chrome and tied to your Google account when you are signed into Chrome. PromptShield does not operate its own account system for this data.

Website content

The extension accesses text content in the supported AI chat pages only to perform its safety checks and related UI (such as a typing hint). It does not upload that content to PromptShield developers for analysis.

Children’s privacy

PromptShield is not directed at children. Parents or guardians should supervise minors’ use of AI tools and browser extensions.

Changes

We may update this policy if the extension’s behavior changes. The “Last updated” date will change when we do.
