Off by default. If a parent turns this on, the game shares only totals such as play visits, missions started, broad maths topics, hint use, boss encounters, coarse active-play milestones, and a speed bucket. No exact duration, names, answers, ages, cookies, IDs, or advertising data.
Monster Math stays free and ad-free. Parents and other grown-ups can optionally help cover hosting and future learning improvements. Contributing never changes gameplay.
Monster Math is free to play. If you would like to help keep it online and improve it, you can make an optional contribution. There is no pressure to contribute.
Contributions help with the domain and hosting, security and testing, accessibility improvements, new Maths Coach content, and future artwork.
Contributing does not unlock levels, blasters, armour, coins, scores, easier questions, or any other gameplay benefit. Every child gets the same learning game.
After a grown-up chooses to continue, Stripe opens in a new tab. No Stripe code runs inside Monster Math, and Monster Math does not receive or store card details.
This is a voluntary contribution to support the project. It is not a charitable donation and is not tax-deductible. No goods, services, or in-game benefits are provided in return.
Stripe handles the information entered on its hosted checkout page. Nothing about a contribution changes a child's game.
Children should ask a parent or guardian. Supporting is optional, gives no gameplay advantage, and is not a tax-deductible donation.
The support page is ready, but no payment link has been connected.
Monster Math is built to work without a child account.
Player slots, answers summary, settings, and rewards are saved in this browser. They are not uploaded. A parent can download a backup or erase a slot.
The site automatically counts successful home-page loads as likely browsers, recognised bots, or unknown clients. Browser details are reduced to one of those three labels at the edge and are not stored. We do not keep IP addresses, cookies, device IDs, referrers, searches, or individual visit histories.
A parent may opt in to coarse, same-site counters, including anonymous play visits and one-, five-, fifteen-, or thirty-minute active-play milestones. They never include exact duration, names, typed text, raw questions or answers, exact ages, cookies, device IDs, session IDs, or advertising IDs. The local queue can be deleted at any time.
There are no advertising trackers, personalised ads, social logins, or third-party analytics. Optional support is shown only in the Parent Zone and opens a separate Stripe-hosted page after a grown-up confirms.
Set the challenge and make the game comfortable for you.
