Privacy

What the website and browser extension read, send and keep.

Updated 12 November 2026. What came of it? is operated by James Pacileo.

Reading the site

No account is needed. We do not add analytics, set tracking cookies, keep reader profiles, or sell information about readers. Searching the published claims happens in your browser. A marker in your browser's session storage stops the wordmark animation repeating in the same tab; it is not sent to us.

Cloudflare hosts and protects the site. Requests for pages and files pass through its network, which receives information such as your IP address and browser request details and counts requests and errors. Our application's request logging is disabled. Cloudflare's processing is described in its privacy policy.

Opening the extension

When you open the extension, it reads the current tab's address and compares it with a public lookup file inside your browser. It does not send that page address to our service. It downloads the lookup file from whatcameofit.com and saves the file and its retrieval time in the browser, refreshing it after six hours. If the site cannot be reached, the saved copy can still be used. Removing the extension removes this local cache.

Optional registry searches

A registry search runs only when you press its search button. On the website, it sends the address or text you supply to our Cloudflare service. The service may read the article, a public post and its linked article, and sends the text to OpenAI to identify the treatment and condition being reported. It searches ClinicalTrials.gov and Europe PMC using treatment names, the reported condition and research identifiers, then uses OpenAI to compare the trial records. The result is marked as an automatic, unreviewed search.

In the extension, pressing the search button reads the page or your selected words and sends that text and outgoing links to our service. A selection limits the text sent; outgoing links can still be included. A post also identifies its platform. Up to three X short links may be opened through t.co without cookies or a referrer. The current page's address is not added to the search request, but the text you choose may itself contain personal information. Please use public reports and avoid sending private medical or other sensitive information.

Our application does not store or log submitted addresses, text or search answers. Your IP address is used by Cloudflare to limit the number of searches. We request that OpenAI does not save chat completions for later retrieval. This does not mean zero retention: OpenAI may keep prompts and responses in abuse-monitoring logs for up to 30 days, or longer for legal or safety reasons, and may temporarily cache model inputs. API data is not used to train models by default. Processing may take place outside your country. SeeOpenAI's data controls.

Automatic search has a limited monthly allowance. When it is used, reviewed claim pages remain available. A search never creates a reviewed claim or changes a claim's status.

Writing to us

Suggestion and correction links open your mail application. Nothing is sent until you send the email. Cloudflare forwards it to our Google Workspace inbox. Your address and message are used to handle your request, not to subscribe you to a mailing list. Please avoid including private medical records or other information that is unnecessary for the request.
