Your email address, because it is how you sign in. A name, if you give one during setup or if it comes from Microsoft, Google or Apple when you use them to sign in. The company you work for and the domain of your work address, which is read from that address rather than asked for. What you do, meaning the kind of work you named at setup and roughly how far into your career you are. The modules you say you work in, and which of them is your main one, because answers are scoped to it. Your conversations, meaning the questions you ask and the answers you are given, so that your threads are there when you come back and on your other devices.

The setup answers are used to scope your answers, to decide which module a question belongs to, and to understand who this product is for. Your work domain is also how we recognise that several people from the same firm are using Propfessor, so we can deal with that firm once rather than as separate strangers.

That is the whole list. There is no tracking of you around the internet, no advertising identifiers, no profile built from your behaviour, and nothing is sold or shared for marketing by anyone.

A short-lived count of how many questions you have asked, held in your own browser, so the free trial can end. Nothing about you is stored on our side until you create an account.

We are asked to keep the questions people ask, so we can decide what this trainer learns next. That only happens if you tick the box, and if you do, the question is stored against a random browser token, never your name and never your account. Email addresses and phone numbers typed into a question are stripped before it is stored. The answers themselves are not stored in that log. You can withdraw at any time, and nothing is kept after you do.

Separately, and regardless of that choice, we count how many questions were asked in each module each day. That count contains nothing about anybody.

A sign-in cookie so you stay signed in, and a random participant token used only for the consent choice above. Two short-lived cookies exist during a Google or Microsoft sign-in to protect that exchange, and are deleted the moment it finishes. There are no advertising or analytics cookies.

The database is Neon, in Frankfurt. Hosting is Vercel. Sign-in emails are delivered by Resend, in Ireland. Answers are generated by language models reached through OpenRouter, and the search over our own material uses Voyage AI. Payment, when it arrives, will be handled by Lemon Squeezy, and card details will never reach us.

Your questions and answers are sent to a model provider in order to be answered. They are not used by us to train a public model.

Your account and threads stay until you remove them. You can delete any thread in the product, and it is gone. Sign-in codes expire in ten minutes, sessions in ninety days. Consent records are kept as a dated ledger, because a record of permission has to survive being checked.

A copy of what is held about you, a correction, or deletion of the whole account and everything in it. Write to admin@propfessor.com and it will be done. If you are in the UK or the EU, this is your right under the GDPR and you may also complain to your national data protection authority.
