Where your text goes

You are about to paste a real message into a text box. It has your pricing in it and somebody’s actual name. Fair question: what happens to it?

Where does the text go?

To us, and to three companies, each with one job. Vercel runs the site and routes the request to the model, so the text passes through it. Anthropic runs the model that does the coaching and sends back the marks and the score. Neon runs the database your text is then stored in. That is the round trip.

Three other companies are part of the product and never see a message: Clerk signs you in, Stripe takes the payment, and Vemetric counts page views on this site. None of them is on the path your text takes. The full list, with what each can see, is in the privacy policy.

Does it train a model?

No. As of 2026-09-01, Anthropic’s commercial terms say they do not train their models on what businesses send through the API. We do not train anything on it either, we do not sell it, and no advertiser or data broker sees it. The analytics counting page views on this site never sees a message either: it runs without cookies, keeps a country rather than your IP address, and has no access to anything you write in the app.

One footnote on that round trip: like most API providers, Anthropic holds inputs and outputs for a limited period to check for abuse before deleting them. That is not training, but it is not instant deletion either, and you should know it happens.

There is one thing beyond the coaching we would like to do with sessions, and it will be opt-in and off by default. If you tell the app whether a message got a reply, that answer may be counted alongside other people’s answers, to check whether the habits the coach marks down actually cost replies. Counts only. Never your text, never anything that identifies you, never the name of the person you wrote to. Nothing happens until you turn it on, and leaving it off costs you nothing.

Who here can read it?

Sell a Pen is run by one person, and that person has access to the database. In practice that means opening a session to fix a bug you reported, or when something breaks. Not browsing. There is no team, no sales department and no dashboard where your drafts show up next to your name. Beyond that one person, the only others who can reach it are the companies listed in the privacy policy, each under a data processing agreement that limits them to running the service for us.

How long is it kept?

For as long as your account is open. That is deliberate: the coach gets sharper the more of your history it has to compare against, which is the point of the weak-spot profile. If you want a session gone before then, email contact@sellapen.com and we delete it, and the profile adjusts around what is left. Wherever the app gives you a delete button for it, that does the same thing.

What happens when I delete my account?

Sessions, messages and business context go from the live database straight away. They leave the encrypted backups within 30 days, as those roll off. Billing records stick around longer, because tax law says they have to.

What if I would rather not paste a real name?

Then do not. Call her Dana. Call the company a Series A fintech. The coaching works exactly the same, because what it marks is your structure: whether you led with her problem, whether you used one real number, whether you asked for one thing. It never needs to know who the person actually is. Redact freely.

The formal version of all this is the privacy policy, and the rest of the deal is in the terms. If something here is not clear enough, email contact@sellapen.com and we will fix the page.
