Privacy Policy

Who runs the App

Paper Trading Lab is run by Bycha Buxton (Aerial Imagery LLC), in California. This policy explains what we collect, why, and who helps us run the App.

What we collect

Email address and name, so you can sign in and we can identify you.

Acceptance logs: which user accepted which document, which version, and when (a timestamp). We keep these as a record of your agreement.

Your practice trades and quiz answers inside the App, so we can show your progress.

Your questions to the Floor Coach. What you type, or say in a voice session, is sent to our AI provider (OpenAI) to produce an answer, together with your first name if you gave one and the page you are looking at. We don't keep a copy of your typed or spoken conversations ourselves; we keep only the amount and cost of AI use per person, so we can apply daily limits and monthly allowances.

How you found us. If you arrive from an ad or a link with tracking tags (such as utm_source or an X click id, twclid), we store that tag with your account to learn which ads bring people who use the App. We also load the X (Twitter) Pixel on each page so we can measure those ads. The pixel may set a cookie and tell X which pages were viewed and that an invite request was submitted. We don't send X your name or email, and we don't use any other advertising pixels.

Your IP address and browser type. We keep IP addresses for about a day to limit abuse (for example, too many sign-in requests), and we record your browser type with each acceptance log.

If you subscribe to Pro: payments are handled by Stripe. We receive your subscription status, renewal date, a Stripe customer ID and a card fingerprint (an anonymous code for the card, used to allow one free trial per card). We never see or store your card number.

Cookies

We use a session cookie to keep you signed in. The X (Twitter) Pixel may also set a cookie to measure our ads. We don't use any other advertising cookies.

Service providers

We use a few outside companies to run the App. They handle data only to provide their service to us.

Cloudflare: hosts the App and its data.

OpenAI: provides the AI models behind the bots and the Floor Coach. For the bots we send market data and public headlines. For the Floor Coach we also send what you type or say, your first name if you gave one, and the page you are on, so it can answer you. We don't send your email address.

TypeSafe: provides the Jev model. We send it only market data and public headlines.

Stripe: processes Pro subscription payments. It receives your email and payment details directly from you. We receive from Stripe your subscription status and renewal date, and a card fingerprint (an anonymous code for the card, not the card number), which we use to allow one free trial per card.

An email provider: sends your sign-in links (magic links), so it receives your email address.

X (Twitter): when the advertising pixel is on, X receives technical data about your visit (pages viewed, the ad click id, and that an invite request was submitted) so we can measure our ads. We don't send X your name or email address.

What we don't do

We don't sell your personal information. We don't share your name or email with advertisers or sponsors. We do share the limited technical data described above with X, only to measure our own ads.

Keeping and deleting your data

We keep your information while your access is active and as long as reasonably needed afterward, for example to keep acceptance records.

To ask us to see or delete your data, email the owner. We'll respond within a reasonable time. We may keep limited records when the law requires or allows it, such as proof that you accepted our terms.

California residents

California law may give you rights to know, delete, and correct your personal information, and not to be treated differently for using those rights. Email the owner to make a request.

Children

The App is not meant for children under 13, and we don't knowingly collect their information.

Changes

We may update this policy. When we do, we'll change the version date and may ask you to review it again.
