Mondo Knows
Privacy Policy
Last updated: 25 October 2026
The short version: Mondo Knows has no accounts, no sign-up and no server that stores what you do. Your scores and streaks stay in your own browser. The one thing that can leave your device is anonymous page-view analytics, and only if you switch it on in the cookie banner. Both are explained below.
What stays on your device
Games, quizzes, puzzles and challenges save your results in your browser's local storage, under keys beginning with mondo.. That covers your daily streak, your score history and your personal bests. This information never leaves your device and Mondo Knows cannot read it.
Because it lives in your browser, clearing your browser data, using private browsing, or switching device will reset it. There is no way to recover a streak, which is the trade-off for not having accounts.
Analytics
The site uses Google Analytics 4 to understand which pages are used, so effort goes into the parts that help people. It sets cookies and collects information such as the pages you view, roughly where you are (usually to city level), your device and browser type, and how you arrived at the site. It is not used to identify you personally, and Mondo Knows does not combine it with any other data.
- Google's own privacy practices: policies.google.com/privacy
- To opt out of Google Analytics across all sites, install the Google Analytics opt-out browser add-on.
Analytics only after you allow it
Analytics is off until you turn it on. The site loads Google Analytics in consent mode with analytics storage denied, so until you make a choice no analytics cookie is written and nothing is stored on your device. The cookie banner offers one switch for analytics; leaving it off keeps analytics storage denied, and turning it off later withdraws consent for the rest of your visit and for future visits. Advertising storage is always denied, because there are no ads on the site.
If you allow analytics, Google Analytics may set cookies such as _ga and read a random client identifier so repeat visits are counted once. The data described above is then sent to Google. Your game scores, streaks and calculator inputs are never included: they stay in your browser's local storage and are not part of any analytics request.
Your choice is remembered in your browser, so you are not asked again on every page.
Hosting and server logs
The site is served by Vercel, which processes standard web request data such as your IP address and browser user agent in order to deliver the pages and protect against abuse. This is normal for any website and is not used to build a profile of you.
Advertising
There is currently no advertising on Mondo Knows. If advertising is introduced, this policy will be updated before any ad is served, and the following will apply:
- 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 based on your visits to this site and others. You can opt out of personalised advertising in Google Ads Settings, or opt out of third-party vendor cookies at aboutads.info.
- Ads, if they appear, will be kept out of the way of game controls and quiz answers, and will be clearly distinguishable from content.
Children
Mondo Knows is not directed at children under 13 and does not knowingly collect personal information from them. There is nothing to sign up for and nothing to submit.
Your choices
You can block or delete cookies in your browser settings, and clear the locally stored scores at any time. Blocking analytics cookies does not affect any feature of the site: every game, quiz and calculator works without them. The consent bar on your first visit records the choice you made, and Cookie settings in the footer opens it again whenever you want to switch analytics on or off.
Changes to this policy
If what the site does with data changes, this page changes with it and the date at the top is updated. Material changes will be noted on the site rather than made silently.
