Privacy Policy
Last updated 13 August 2026
The short version. We collect your email, and the minimum needed to
keep you signed in and to know whether you have paid. We do not sell your data, we do not
share it with advertisers, and we do not track you around the internet. We never see your
card number.
1. What we collect
- Your email address, when you join the waitlist or subscribe. It is
how we identify your account and how we reach you.
- Session data. When you sign in we store a one-way hash of your
session identifier, the expiry, and the browser's user-agent string. We do not store the
identifier itself, so a copy of our database cannot be used to sign in as you.
- Subscription status — which plan you are on and when it started and
ends.
- Preferences you set, such as your sportsbook and your state. Your
sportsbook and state are stored on your device and are sent to us only if you
are signed in and we need them to build a bet-slip link.
- Chat messages, if you use the assistant, so the conversation has
memory and so we can enforce usage limits.
2. What we do not collect
- Card numbers. Payments go through Stripe. Your card details go to
Stripe, never to us — we receive only a customer reference and whether the payment
succeeded.
- Your bets. Certy is not a sportsbook. We do not know what you wagered,
how much, or whether it won. Tapping a bet-slip link hands you to the book; what happens
there is between you and them.
- Advertising or cross-site trackers. There are none in the app. We do
not build an advertising profile of you and we do not sell or rent your data to anybody.
- Precise location. We never ask for it. If you tell us your state, it
is because you chose it from a list.
3. Why we collect it
To sign you in, to know whether you are entitled to the paid board, to take payment, to
send you the emails you asked for, and to stop abuse. That is the whole list. We do not use
your data to train anything or to profile you.
4. Who else sees it
Only the services that make Certy work:
- Stripe — payments and subscription state.
- Supabase — our database, where accounts and the public record live.
- Cloudflare — hosting and delivery.
- Anthropic — if you use the chat assistant, your message is sent to
the model to answer it.
Each holds data only to provide their service to us. We will disclose data if the law
actually requires it, and we will tell you unless we are forbidden to.
5. Cookies
One cookie, certy_sess, which keeps you signed in. It is HttpOnly, Secure
and SameSite=Lax — script cannot read it and it does not ride along on other sites'
requests. There are no analytics or advertising cookies. Signing out clears it.
6. How long we keep it
- Sessions expire after 60 days, or immediately when you sign out.
- Sign-in codes expire within hours and are single-use.
- Account and subscription records are kept while your account exists, and afterwards
only as long as tax and accounting rules require.
- The public record of our own picks is permanent by design — but it is about
our calls, and contains nothing about you.
7. Your choices
- See it, correct it, or delete it. Email us and we will.
- Delete your account and we remove your email, sessions, preferences
and chat history. Payment records we are legally required to keep, we keep.
- Stop the emails — reply to any of them, or ask us.
- If you are in California, the EU or the UK, you have additional rights over access,
portability, correction and erasure. Ask and we will honour them; we do not sell personal
information, so there is nothing to opt out of.
8. Security
Secrets live server-side and are never shipped to the browser. Sign-in tokens and session
identifiers are stored only as one-way hashes. Database access is deny-by-default: the
public key can read the published record and add a waitlist signup, and nothing else. No
system is perfect, and if we ever have a breach affecting you we will tell you promptly and
plainly.
9. Children
Certy is 21+. We do not knowingly collect data from anyone under 21, and we delete it if
we discover we have.
10. Changes
If we change how we use your data in a way that matters, we will tell you before it takes
effect rather than quietly updating this page.
