You're about to share a real conversation with real people in it. So here is every piece of it, and exactly who sees that piece.
Your word-for-word transcript
It exists in memory while Mirror reads it, then it's gone. There's no copy to go back to — not for the person who operates Mirror, not for you, not for anyone with a subpoena.

The lines Mirror quotes back to you
To show you the moment something turned, Mirror repeats the actual sentence — sometimes one another person said. This is the one real exception to "your transcript disappears," and it's why it's on this page instead of buried somewhere.
What you wrote about yourself
Your honest read on how it went, anything you were worried about, what you took away, what you decided to try. This is the heart of it — comparing your story to the room's is the entire product, and it's what makes coming back worth anything.
Who was in the room
Half of what Mirror measures only means anything relative to status — being interrupted by your report and by your CEO are different events. It can't read the room without knowing who holds what.
Your scores and coaching
These are reviewed to judge whether the coaching is any good and to improve it. Nobody else sees them — not Anthropic after the analysis, not Stripe, not PostHog, and not anyone else using Mirror.
Your email address
The email service that delivers your sign-in link sees your address and the link itself. Nothing about your meeting ever passes through it.
Your payment
Your card is typed on Stripe's page, not on Mirror's — the number never touches this site. All Mirror asks Stripe afterwards is "was this paid, and which email paid it," so it knows to let you in. Stripe never learns you use Mirror to read meetings, and never sees a transcript, a score, or a word of coaching.
Which ad brought you here
Mirror is advertised on Reddit, and this is how it is measured which ad worked. It runs on the ad pages and the page you land on after paying. It does not run on any page that holds a read — those pages carry no third-party script at all, so there is nothing there to record. What reaches PostHog from inside Mirror is sent by the server, not your browser, and amounts to "someone opened a report": no transcript, no scores, no coaching, and never your email address.
Not sold, not shared, not published, not used to train anything. Other people using Mirror cannot see a single thing you wrote.
The honest version of the tracking question: the ad pages are measured, because that is how it becomes clear which ad is worth paying for. The pages that hold your read are not. There's no third-party script on them at all — no advertising cookies, no session recording, no pixels — which is a stronger promise than "we don't look," because there's nothing there that could.
Your results live at a web address long enough that guessing it isn't realistic — and even then, you have to be signed in as you to open it. If you forwarded the exact link to a colleague, they'd see nothing.
Worth saying out loud: if a meeting is sensitive enough that a few quoted lines being readable by Mirror's operator would be a problem, use a different meeting. Everything else here is genuinely private — but that part isn't, and you should decide knowing it.
Ask, and it's deleted — all of it, permanently, no reason needed. Reply to any email from Mirror and say the word. Stripe keeps its own record of the payment, because it has to for tax and accounting; everything Mirror holds goes.
