Privacy Policy

• We collect what we need to run your account, your subscription, the emails and alerts you choose, and to keep the service secure.
• We do not sell your personal information.
• The iPhone app does not track you: no advertising tags run in it. The website uses Google Analytics and a Google Ads conversion tag (details below).
• You can delete your account and its data yourself, any time, from Delete Account.
• Questions: [email protected].

Prediction Engine ("we", "us") runs the website predictionengine.app and the Prediction Engine iPhone app, a sports-analytics service that publishes model predictions and grades every one in public. We do not take bets and no money is wagered through the service. This policy covers both the website and the app.

Account: Your email address and a password, which is stored only as a one-way hash by our sign-in provider. If you sign in with Google or Apple, we receive your name and email address from them (with Apple you may choose to share a private relay address instead). We also keep the display name you choose and your sign-up date.

Subscription and payments: Payments are handled by Stripe. We never see or store your full card number or security code. From Stripe we keep your customer and subscription identifiers, your plan, its status and renewal dates, and your charge history, and we read a non-reversible card identifier that lets us recognise a card already used for a free trial (one trial per person).

What you do in your account: Picks or bets you choose to log on My Dashboard, badges, referral codes, and your leaderboard standing.

Pages you visit while signed in: When you are signed in, we record which pages of the service you open, with the time, your IP address and your browser or device type. We use this to run the service, understand which features people use, and investigate abuse.

How you found us: The page you first landed on, the referring site and campaign tags (UTM parameters) are stored in your browser and, if you subscribe, attached to your Stripe checkout so we know which pages and campaigns lead to subscriptions.

Email: If you sign up for our email, or have an account, we keep your email address, whether you confirmed it, where you signed up, and whether you unsubscribed.

Push notifications (iPhone app): Only if you turn on alerts: your device's push token from Apple and the sports and alert types you chose.

Account help assistant: If you use the assistant on the Manage Plan page, and only after you agree to the notice it shows, your questions and your account's billing details are sent to Anthropic to generate the answer. We do not store the conversation.

Analytics: See section 4.

We do not collect your precise location, contacts, photos or health data. We do not knowingly collect sensitive personal information.

• To provide the service: your account, sign-in, subscription access, boards, live trackers and your dashboard.
• To bill your subscription through Stripe and to prevent repeat free trials and payment fraud.
• To send the emails you signed up for, and to account holders a weekly email with last week's graded record and the week's board, with occasional offers. Every email has a one-click unsubscribe, and unsubscribing never affects your account.
• To send the push alerts you turned on (for example "picks are up" or "yesterday's picks graded").
• To answer your support questions, including through the assistant if you choose to use it.
• To measure which pages and campaigns work (website only for advertising measurement; see section 4).
• To keep the service secure and to enforce our Terms of Service.

We do not use your personal information to train our prediction models; they are trained on sports data.

Essential: A sign-in session cookie (NextAuth) and a few settings stored in your browser, such as a remembered sport or a confirmed notice. The service does not work without the session cookie.

Website: We use Google Analytics 4 to count visits and see which pages are used, and a Google Ads tag that tells Google when a visit from one of our ads leads to a trial. Google sets its own cookies for this and processes the data under its policies. You can opt out with Google's Analytics opt-out add-on and Google's ad settings, or by blocking cookies in your browser.

iPhone app: The app does not track you across other companies' apps or websites. No advertising tag runs in it: the Google Ads tag is switched off, advertising consent is denied, and Google Analytics runs only as first-party usage analytics with Google Signals and ad personalisation turned off.

We share personal information only with the service providers that run parts of the service for us:

• Supabase — database and sign-in
• Amazon Web Services — the servers that run the site (Ireland)
• Cloudflare — network, security and bot protection (sees your IP address)
• Stripe — payments and subscriptions
• Resend — email delivery
• Google — Google Analytics and Google Ads (website), Sign in with Google
• Apple — Sign in with Apple, and push notification delivery (Apple Push Notification service)
• Anthropic — the account help assistant, only if you agree to use it

Each processes the data under its own terms and privacy policy and is bound to protect it. We also disclose information when the law requires it, to protect our rights or users' safety, or as part of a sale or transfer of the service. We do not sell personal information, and we do not share it with data brokers.

• Account, dashboard, page-visit and push-alert data: for as long as your account exists, then deleted with it.
• Email list: until you unsubscribe or delete your account. If you unsubscribe we keep the address marked as unsubscribed so we do not email you again.
• Payment records: Stripe keeps invoices and payment records as tax and financial law requires, even after you delete your account.
• Google Analytics data: kept by Google for the retention period set in our Analytics account.

Delete your account yourself, at any time, on the website or in the app: Manage Plan → Delete Account (in the app: Account → Delete account). Deleting cancels any active subscription and removes your profile, logged picks, email-list entry, page-visit history, push alert settings and sign-in record, and deletes your customer record at Stripe. If you signed in with Apple, we also ask Apple to revoke our access to your Apple ID. It cannot be undone. Completed billing periods are not refunded (see the Terms).

If anything is left over, or you cannot sign in, email us and we will delete it within 30 days.

• Unsubscribe from email with the link in any email.
• Turn push alerts off in the app (Alerts) or in iPhone Settings → Notifications.
• Opt out of Google Analytics and ad measurement on the website as described in section 4.
• Ask us for a copy of your data, to correct it, or to delete it, by email. Depending on where you live (for example California, Virginia or Colorado, or the EU/UK) you may have these and other rights by law; we honour them for everyone and will not treat you differently for using them.

Traffic is encrypted with HTTPS. Passwords are stored only as hashes by our sign-in provider, payment details stay with Stripe, and databases holding personal information are not readable from the browser. No system is perfectly secure; if we learn of a breach affecting you, we will tell you as the law requires.

The service is for adults: you must be at least 18, and 21 where the law requires (see the Terms). We do not knowingly collect information from anyone younger; if you believe we have, email us and we will delete it.

We are based in the United States. Our servers are in Ireland and our providers may process data in the United States, the EU and other countries, with the safeguards their terms provide.

We will post changes here with a new effective date. If a change materially affects how we use information we already hold, we will tell account holders by email before it applies.
