Privacy policy

Last updated 15 November 2026

This policy explains what big4dle (“we”, “us”) collects when you use big4dle.bahaykubo.xyz, and what we do with it. We collect as little as possible. You do not need an account to play.

What stays on your device

Your results, streaks, which rounds you have rated and your settings are stored in your browser’s local storage, in keys starting with b4:. This data stays on your device unless you choose to share it. You can remove it any time under Settings or by clearing your browser data. Playing the game does not set any cookies.

What you choose to send us

• Question ideas: the text you type (up to 140 characters) and a timestamp.
• Ratings: your rating from 1 to 5, the date of the round, the list of prompts in that round (with the school), and a timestamp.

We do not store your name, email address, IP address or any account identifier with these submissions. Please do not include personal information in what you write, and please do not name real people. If a submission contains something that looks like an email address or phone number, we remove it, and we discard submissions with blocked words. We use submissions only to improve the game. To delete one, contact us with the text you sent and roughly when. Because submissions are not linked to you, we can only find them by that text and time.

Preventing abuse

To limit spam, our server computes a short, salted, one-way hash from your IP address, browser type and the date. It is kept for up to 24 hours only to count how many times a device has submitted something that day. It is never stored with your submission and cannot be reversed to find your IP address.

Supporters and Ko-fi

If you support us on Ko-fi, Ko-fi processes your payment under its own terms and privacy policy, and we never see your card details. Supporting once unlocks our games, including big4dle. For each payment Ko-fi sends us a notice. We read only its type, the email address you used and the time, and keep a message id so a repeated notice is not counted twice. We store your email address, what it unlocks and when it ends. To restore access on a device, you enter your Ko-fi email and we send a one-time sign-in link by email; we store only a hash of its code, and it works once and expires after 15 minutes. Using it sets one cookie, HttpOnly and SameSite=Strict, that lasts 30 days and holds a signed copy of your email that only our server can read. You can sign out or ask us to delete your supporter information at any time.

Advertising

Free players may see ads on the start page and the results page. We use Google AdSense. Google and its partners may use cookies and similar technologies to show and measure ads. We never show ads during gameplay. No ad script loads and no ad cookie is set until you press Accept on the banner; if you decline or ignore it, you see no ads. Your choice is saved on your device, and clearing your browser data asks you again. Supporters see no ads.

Analytics

We do not currently use analytics tools. If we add any, we will describe them here and, where required, ask for your consent first.

Hosting and logs

The site is served through Cloudflare, which may process technical data such as your IP address and request details to deliver the site and protect it from attacks, under its own privacy policy.

Children

big4dle is a general-audience game and is not directed at children under 13. We do not knowingly collect personal information from children. If you believe a child has sent us personal information, contact us and we will delete it.

Your choices and rights

Depending on where you live, you may have the right to access, correct or delete personal information we hold about you, to object to or restrict certain processing, and to withdraw consent. Because we hold almost no personal information, most requests concern supporter email addresses. Contact us at hello@bahaykubo.xyz and we will respond.

Changes

If we change this policy we will update the date above, and for significant changes we will say so on the site.
