Odds & Markets

Privacy policy

Draft: pending counsel review. This document has not yet received final legal sign-off and may change.

The short version

Odds & Markets has no user accounts, no login and no profiles. You can browse and compare prices without giving us anything. If you sign up for the weekly line report, or use one of the other forms described below, we keep the details you enter: your name, email address, mobile phone number and state, along with the consents you gave. We use them to send you what you asked for and to keep you on our email list. We do not sell your name, email or phone number.

What we keep when you sign up

The line report signup form collects, and we store:

  • Your first name, email address, mobile phone number and state.
  • Which report you asked for, and your confirmation that you are 21 or older.
  • Your consent to receive the report by email, with the wording you agreed to.
  • If you tick the box to receive texts: that consent, the exact wording and its version, when you gave it, the page you gave it on and the IP address it came from. Texting is opt-in and separate from giving us your number.
  • How you reached us: the page you arrived on, the referring site, and any advertising click identifiers or campaign tags in the link you followed (for example gclid and utm_ tags). We may keep these in a first-party cookie in your browser for up to 90 days, so a sign-up on a later page is credited to the ad that brought you. The cookie is not written if you have opted out below.
  • The IP address and browser user agent of the submission, when it was made, and how many times you have submitted.

The “keep this on file” card on the ledger and saved-items pages collects your email address and mobile number, with the same optional texting consent, and the request-a-market form collects your email address, mobile number and the request you type. Each is stored the same way, with the same request details.

We use these details to email you the report you asked for, to add you to our email list, to text you only if you opted in, and to measure which advertising brings sign-ups. If a sign-up cannot be saved, the details are emailed to our own staff so they can add it by hand.

Data kept in your browser only

  • Your last confirmed selection, so a refresh doesn't lose it (per tab).
  • An optional “my usual book” tag, stored in localStorage and never sent to any server-side profile.
  • Theme preference (light/dark) and odds-format preference.
  • Your selected state/jurisdiction, used to filter venue availability.
  • An age-gate acknowledgement cookie, so the gate doesn't reappear every visit.
  • Your analytics choice (om-consent), so the notice doesn't reappear every visit.

Clearing your browser storage removes all of it. None of this is required reading for us, it exists so the site works, not so we can identify you.

Click events

When you follow a “Go to [venue]” link, we write one record before redirecting you. Its complete field list:

  • occurred_at: timestamp of the click.
  • venue_id: which venue the link points to.
  • network: the affiliate link mechanism used.
  • tracker: a placement string (for example, which page the click came from).
  • click_id: an internal identifier built from a timestamp and a salted, non-reversible hash; it is never sent to any affiliate network and cannot be reversed into anything about you.
  • context_route: the on-site placement the click originated from.

No name, email, phone number, account identifier or precise location appears in a click event. See the affiliate disclosure for why these records exist.

Analytics and audience sharing

We use PostHog, a product-analytics service, to understand how the site is used: which pages are viewed, which markets get priced, which venues get clicked, the state you selected, your theme, and general browser and device details. PostHog sets a first-party cookie holding a random identifier so that repeat visits from the same browser count as one visitor. We never send it your name, your email, or anything you type into the site. Requests travel through our own domain to PostHog's US servers.

We also use Google Analytics to count page views and sign-ups, and the Google Ads tag to report a completed sign-up to Google Ads as a conversion. Google sets its own cookies for this. The sign-up event carries the form, your state, the report you chose and whether you opted in to texts; it never carries your name, email or phone number. These Google tags load on every page when they are configured; the opt-out below turns off PostHog and the attribution cookie. Google's own controls, such as its ads settings and the Google Analytics opt-out browser add-on, apply to Google.

Odds & Markets is one of several sports brands affiliated through GSI Media LLC, alongside WagerBird, Advanced Sports Data and StatNerds. We may share analytics and audience data (the random identifier and the events above) with those sister brands to build advertising audiences and to measure campaigns across our sites. Under California and Texas privacy law this counts as “selling” or “sharing” personal information, and you can opt out at any time.

To opt out: use the link (also in the footer of every page) and turn off “Analytics and audience sharing”. The choice is saved in your browser and takes effect immediately; if analytics was on, its cookie is removed.

If your browser sends a Global Privacy Control signal, we treat it as an opt-out automatically: analytics stays off and the setting shows as off, with nothing for you to do.

When analytics is on and you follow a venue link, a salted, non-reversible token derived from the analytics identifier is included in the referral code so a venue sign-up can be attributed to the visit that led to it. The identifier itself is never sent to a venue.

Third-party processors

A small number of infrastructure providers process data on our behalf:

  • Vercel: hosts the site and receives standard request data (such as IP address and browser details) for every page you load; its Web Analytics and Speed Insights give us aggregate page-view and performance counts.
  • Upstash: our database. It stores the sign-up details listed above, click events and the prices we display.
  • Postmark: delivers our emails, including the report you asked for; it receives your name and email address and the message we send.
  • AWeber: our email list; it receives your name, email address, state, mobile number, the form you used and an advertising label (a campaign name or “google-ads”).
  • GSI Media's shared lead records: the details you give on the report form (name, email address, mobile number, state, your email and text consent choices and the campaign that brought you) are kept in GSI Media LLC's lead store, which runs on the WagerBird platform, and in its customer relationship manager, Attio, so our affiliated brands handle you as one person and honour one set of choices.
  • Google Analytics and Google Ads: page-view counts and sign-up conversions, as described above.
  • PostHog: product analytics, as described above; opt out via the cookie settings.
  • Odds and prediction-market data vendors: supply the prices we display; they receive no visitor data from us.

When you continue to a venue, that venue's own privacy policy governs from the moment you arrive there, including any referral identifier its affiliate network reads from the link.

Your rights and contact

If you signed up, we hold the details listed above and you can ask to see, correct or delete them. If you only browsed, we hold no contact details for you. Contact privacy@oddsandmarkets.com with any privacy question, including requests under your state's privacy law.

Odds & Markets is a GSI Media LLC property. GSI Media LLC is owned by SkyBurst Technology, Inc., which operates the site and is the data controller for the information described on this page.
