Privacy Policy

Effective October 19, 2026

YouKnowBall (“we”, “the site”) is a free daily sports trivia game at youknowball.net. This policy explains what information the site collects and how it’s used.

What we collect

  • An anonymous device ID. The first time you play, your browser creates a random ID and keeps it in local storage. It’s sent with your picks so we can score them and show your results. It isn’t linked to your name or email unless you choose to sign in (below).
  • Your picks. The answers you lock in are stored with that device ID and the date, so we can count how many players named each answer and show the daily Board.
  • Friends leagues you join. The nickname you pick, which leagues you’re in, and the reactions you leave on friends’ cards. Other members of a league see your nickname, your scores for days you’ve both finished, and reactions. Any member can share a link to the week’s table, which shows nicknames, points and weekly titles (never the league’s invite link) to whoever has it.
  • Feedback you send. Messages from the Feedback button are stored with the page you sent them from and emailed to us through Resend. They’re anonymous unless you choose to add your email address, which we use only to reply.
  • Daily reminders, if you turn them on. Your browser gives us a push address for this device (from Google, Apple, Mozilla or Microsoft, depending on your browser), which we store with your device ID and which reminders you chose. We use it only to send those reminders, through your browser’s push service. Turning reminders off in Settings deletes it.
  • Your theme and settings (light, dark or system, colorblind mode, sound, share links) are kept in your browser’s local storage and never sent to us.

Apart from what you choose to give us (an email left with feedback, a league nickname, or your name and email if you sign in with Google), we don’t ask for or store names, email addresses, passwords or payment details (Stripe handles card details when you buy Pro; see below), and we don’t sell or share your information.

Signing in with Google (optional)

You never need an account to play. If you choose to sign in with Google, Google tells us your Google account ID (a number that identifies your account to us), your name and your email address. We don’t get your password, contacts, files or anything else in your Google account, and we don’t request any other access.

We use that information only to run your account: to link the browsers you sign in on, so your streaks, picks, replays and leagues follow you, and to show you which account you’re signed in with. When you sign in on a new browser, what you played there is merged into your account; where you played the same game on both, we keep your better result. We don’t send marketing email, and we never sell or share this information or use it for advertising.

YouKnowBall’s use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.

The Sign in with Google button is provided by Google and loads only on the account page. Google may set cookies and process information as described in Google’s Privacy Policy. Your account information is stored on our game server until you delete your account.

Buying YouKnowBall Pro

Pro is paid through Stripe’s checkout page. Stripe collects and processes your payment details (card, Apple Pay or Google Pay) under Stripe’s Privacy Policy; we never see or store your card number. From Stripe we keep a record of the purchase: which account bought Pro, the amount and currency, the date, Stripe’s reference numbers for the payment, and any refund. We keep that record even if you delete your account, as purchase and tax records require, but it stops being linked to your name or email.

Hosting and logs

The site is served through Cloudflare, which processes technical data such as your IP address to deliver pages and protect against abuse. See Cloudflare’s privacy policy.

Advertising and cookies

The site may show ads from Google AdSense. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this and other websites. Google’s use of advertising cookies enables it and its partners to serve ads to you based on your visits to this site and/or other sites on the internet.

You can opt out of personalized advertising in Google Ads Settings, or opt out of some third-party vendors’ use of cookies at aboutads.info. Learn more about how Google uses information from sites that use its services. Where required by law (for example in the EEA and UK), you’ll be asked for consent before personalized ads are shown.

Your choices

You can sign out at any time, or delete your account from the account page. Deleting it erases your Google account ID, name and email right away; your play history stays, no longer tied to you, like any anonymous player’s. You can also remove YouKnowBall’s access from your Google account settings, or email us to delete your account and your play history.

Clearing your browser’s site data deletes the device ID and theme choice. Picks already made stay in our game records without any way to tie them back to you. If you’d like us to delete the picks made with a device ID, email us with that ID (it’s the ykb:device-id value in your browser’s local storage).

Children

The site isn’t directed to children under 13, and we don’t knowingly collect personal information from them.

Changes and contact

If this policy changes, we’ll update it on this page with a new effective date. Questions? Email [email protected].
