Confidentiality.

• No accounts. There is nothing to sign up for and no login, so your activity is not tied to an identity.
• No analytics or trackers. The site loads no third-party analytics, advertising, session-replay, or telemetry scripts of any kind.
• No cookies. Perfected sets no cookies.
• No database of your activity. There is no server-side database or store of your searches, results, or exports. Nothing you search is written down on our side to be retrieved later.

Name searches — the company or owner you are investigating — are sent to the server in the body of a POST request, never as part of a web address. As a result:

• The name you search does not appear in the page URL, so it is not written to browser history or bookmarks.
• It does not appear in the standard request-path logs that any web host keeps.
• When you open a result and use “Back to results,” the search re-runs from your browser's own memory — the query is never round-tripped through a link.

Diagnostic logs are also written to avoid recording the specific patents or trademarks you look up; those identifiers are kept out of server log messages.

To carry a search between pages and avoid re-fetching as you sort and page through results, Perfected uses your browser's sessionStorage. This lives only in your browser tab, is never sent to a third party, and is cleared automatically when you close the tab. Nothing is written to disk beyond your browsing session.

To answer a search, Perfected queries the official patent-office data services it needs — for example the USPTO, the European Patent Office, and other national registers. Your query necessarily reaches those offices, because that is the data being searched. It is not sent anywhere else. API credentials for those services stay on the server and are never exposed to your browser.

The register cards also link out to official sources (for example a national patent register or a certified-extract order page). Those are ordinary links you choose to follow; the site is configured so that your search terms are not passed along to them.

• All traffic is served over HTTPS.
• A strict referrer policy ensures the address of a page you are on — and anything it might contain — is not leaked to the external sites you click through to.
• The site declines to be embedded in other pages (X-Frame-Options), disables content-type sniffing, and turns off browser features it does not use (camera, microphone, location, ad-topics).
• Exports (spreadsheets and PDFs) are generated in your browser or streamed directly to you and marked not-to-be-cached — they are not stored on the server.

These measures reduce exposure; they are not a guarantee of secrecy, and it is worth being clear about what they do not cover:

• Searching a register, or following a manual-lookup link, unavoidably tells that patent office or website what you looked up. That is inherent to consulting a public register.
• Like any website, Perfected runs on hosting infrastructure that keeps basic operational logs (timestamps, IP addresses, request paths). The measures above keep your search terms out of those logs, but the fact that a request occurred is ordinary infrastructure data.
• Your own network, browser extensions, and device are outside our control.
• This page describes the engineering measures in place today. It is a good-faith description, not legal advice and not a contract, and the measures may change as the site evolves. For privileged or highly sensitive matters, apply your own firm's judgment and tooling.
