What we collect and what we do with it, in plain words.

When you run a check

We store the URL you pasted, what we derived from the public pages at that URL, the questions we asked, the engines’ answers and the sources they cited, and the time. We keep it so your weekly re-check has something to compare against and so we can correct mistakes.

When you leave an email

We use it to send the full result and the weekly re-check. Every email has an unsubscribe link. We do not sell or share the list.

What we never do

We never ask for your customer data, your CRM, your card details, or logins to other services on this site. If you later become a customer, the only connections are the ones you make deliberately in setup.

Who runs the check

Your questions are sent through their APIs to OpenAI, Anthropic and Google, and to Perplexity where it’s enabled. Their handling of that data is governed by their terms.

What else sees a visit

On the public pages only, PostHog counts page views and the steps of the check, so we can see where the site loses people. A page view carries the page’s path without its query string; the steps of the check carry the product URL you pasted, exactly as you pasted it, with whether you were named, the result’s id, and any campaign tags (utm) on the link that brought you. PostHog never loads on your own pages (setup, your record, your exit page). Cloudflare Turnstile may check that the check form is used by a person. Email is sent through Resend. When something breaks on our servers, an error report goes to Sentry: the route that failed and the error message, with email addresses removed.

Contact

Questions or deletion requests: reply to any email we send, or write to hello@marketrun.co. Unsubscribing from any email deletes your check record.
