Privacy Policy

Last updated: July 14, 2026

The short version PrAIvacy runs entirely on your device. It reads what you type only to find sensitive data and help you redact it, and it never sends that text to a server, ours or anyone else's. There is no account to create, and no tracking, analytics, or telemetry of any kind. The sections below explain exactly how it works.

What PrAIvacy does

PrAIvacy is a Chrome extension with a single purpose: to detect sensitive information in the text you type into supported AI chat sites, and let you redact it in one click before you send. It recognizes things like names, email addresses, phone numbers, postal addresses, links, dates, account identifiers, and secret keys. Detection and redaction is the whole of what it does; it has no other function.

Where your text is processed

All detection happens locally, on your device, inside your browser, using an on-device AI model. As you type into a supported site, PrAIvacy reads your draft only to locate sensitive spans and highlight them, and it redacts them on your device, before anything is sent. That text is never transmitted to us, and never to any third party. What you ultimately choose to send to an AI service is transmitted by that service and governed by its privacy policy, not this one.

What leaves your device

PrAIvacy's only outbound network activity is to Hugging Face, which hosts the AI model, and only if you choose to turn on detection. Before the first download it makes a small request to confirm the model is reachable, and then it downloads the model's files (its weights). The model is downloaded once, and again only when an extension update ships a newer version, which is fetched quietly in the background and swapped in. Every one of these requests brings data to your device; none of them carries the text you type. Once the model is in place, detection runs fully offline. The extension's content security policy limits its connections to its own bundled resources and to Hugging Face (huggingface.co and *.hf.co), and nothing else.

What's stored on your device

Your preferences are saved locally through the browser's chrome.storage, and they stay there: whether protection is on, your sensitivity and per-category settings, your redaction style, any sites you have muted, and a record of which model has been downloaded. If you mark a value as "never flag this," PrAIvacy stores a one-way hash of it rather than the value itself, so the original never touches disk. It also keeps a simple daily count of how many items it detected and redacted, which you can see in the popup. None of this is ever sent to us.

Data we collect

None. Because PrAIvacy transmits nothing you type, there is no user data for us to collect, receive, or store on a server, and we operate no servers that could. We use no analytics, no tracking, no advertising identifiers, and no telemetry, and we have no data to sell or share with anyone.

Third parties

No third party receives your content through PrAIvacy. Hugging Face provides the model file to you; it does not receive anything you write. We share no data with anyone, for the simple reason that we hold none.

Permissions

PrAIvacy requests only the permissions its single purpose requires:

No guarantees

PrAIvacy is free and provided as is. Detection is best-effort: an AI model will not catch every piece of sensitive data, and it may occasionally flag something that turns out to be fine. Treat it as a helpful assistant rather than a guarantee, and use your own judgment about what you share with any AI service. You use PrAIvacy at your own risk.

Changes to this policy

If anything described here changes, we will update this page and the date at the top, and flag any significant change inside the extension itself.
