Which browsers support the SecurePrompt PII redaction extension?

SecurePrompt is available for Chrome, Chromium-based Edge, Brave and Opera via the Chrome Web Store. Firefox and Safari extensions are not currently available. On mobile browsers and iOS/Android, the extension cannot be installed — use the web-based Workspace instead, which works on all browsers and all devices with no installation required.

Does the SecurePrompt extension send any data to external servers?

No. All PII detection and redaction runs locally inside your browser. The extension has no analytics, no tracking, no background network requests, and no connection to any server. This is declared in the Chrome Web Store listing under developer data use disclosure. Your text — whether from ChatGPT, Claude, Gemini or any other page — never leaves your browser during the cleaning process.

Is the SecurePrompt Chrome extension free to use?

Yes, the extension is completely free to install and use. It applies the same PII detection as the free tier of PrivacyPromptAI. For advanced features — including PDF redaction, custom keywords and batch processing — you can activate a Pro licence in the extension settings. The same $20 one-time key works across both the website and the extension.

No. SecurePrompt performs all PII detection locally using JavaScript injected into the browser page. No text you select, no prompt you write, and no redaction result is ever transmitted to our servers.

After installing the extension, select any text on a webpage, right-click, and choose Clean with SecurePrompt. A panel shows the cleaned version with all PII replaced by tokens.
