Last updated October 9, 2026
The short version

- We sell nothing about you, and run no ads and no third-party scripts. What we do not collect
- Stripe takes payments. AI models help score your work. Who else handles it
- 2 cookies, all our own, none for ads. Cookies
- Delete your account in one step, and stop our emails in one click. Your choices
Who we are
AI PhD is run from Detroit, MI. The same team runs AI PhD, trainwithagents, ragcreator, on one database: one account works on all three, and deleting it removes it from all three.
What we collect
- Your email address. You type it to sign in or to buy, and an account exists from the moment you start a checkout with it, even before you sign in.
- The work you send in to be scored: the full text you paste, up to 100,000 characters each time, with its score.
- On ragcreator, the documents you upload to the lab (up to 20 documents, 10 MB each) and the passages cut from them.
- What you bought and when, with Stripe's ids for the payment and the membership. Never your card number.
- Your email choice: whether you asked for practice emails, and when you stopped them.
- Your IP address, only to limit abuse (how many sign-in links or checkouts one address asks for).
What we do not collect
No passwords: you sign in with a link we email you. No card numbers. No tracking pixels in our emails, no third-party scripts on our pages, no ad networks. We do not sell or rent anything about you.
Who else handles it
- Payment processor (Stripe): takes your card and billing details on its own checkout page, under its own privacy policy. We never see your card number.
- Hosting, storage and email delivery: runs the site, holds the database and your uploaded documents, and sends our emails.
- AI model providers: receive the text you submit so a model can help score it, and on ragcreator the passages of your documents so they can be searched.
- Product analytics: receives events such as a purchase or a first score, keyed by a random account id. Never your email, never what you submitted.
The AI app you connect
You can use AI PhD inside your own AI app, for example Claude or ChatGPT. Once you allow it, the app can fetch your next lesson, send your work in for scoring, and read your scores on AI PhD. What the app reads is then also covered by that app's own privacy policy.
The app holds a key that works for 1 hour. It renews the key for up to 90 days, and the connection ends after 30 days unused. To disconnect, remove the connector in your AI app. Deleting your account disconnects every app at once.
Cookies
AI PhD sets only these cookies, all its own, all hidden from page scripts. Nothing else is stored in your browser.
| Name | What it does | Lasts |
|---|---|---|
sid | Keeps you signed in on this school. | 30 days |
ref | Remembers the referral link that brought you, so the friend who shared it gets their reward. | 30 days |
How long we keep it
- Sign-in links work once and expire 15 minutes after we send them.
- A sign-in lasts 30 days, or until you sign out.
- Abuse-limit counters (an IP address, or your email) are cleared as new requests come in, once their window has been over for at least a day.
- Analytics events wait in a queue until they are sent, and are cleared from it 30 days later.
- Everything else in your account stays until you delete the account.
Your choices
- Delete your account in one step at /account/delete. It removes your account on all three schools, your work and scores, your documents, your sign-ins and every connected app, and stops each membership from renewing.
- What deletion keeps: Stripe's own record of your payments (kept for tax and accounting), analytics events already sent (no email, no work in them), our hosting logs for a short time (the IP address of a sign-in request that hit the limit), and a share card you made, which a cache may still serve for up to a day.
- Stop practice emails with the one-click link at the bottom of each one. Sign-in emails come only when you ask for one.
- For a copy of what we hold about you, write to jack@dotcomjack.com. We answer within 30 days.
