Who we are
MJ Kids creates personalized digital games and stories for children. Operated by Marcos Henrique da Silva Andrade, Brazilian tax ID (CNPJ) 51.691.995/0001-15, Brasília - DF, Brazil. Contact: [email protected].
What you buy
A made-to-order digital product, as a one-time purchase or a yearly plan: a browser game and/or narrated stories, in English, with a character drawn from the description you send and with your child's name.
Access is through a personal link that works in the browser of phones, tablets and computers, with no app to download. There are no ads, no in-game purchases and no collection of the child's data while they play.
Yearly plans
The Hero Yearly and Family Yearly plans last 12 months from the payment confirmation. During that time your child gets the full game, one new story a month with the same character (two on Family Yearly) and game updates.
No automatic renewal: you pay once a year. About 30 days before the plan ends we send you an email; it is only renewed if you pay again from your order page.
If you don't renew: the game and the stories already delivered keep working on the device. Only new stories and updates stop.
A one-time story is paid once and is yours to keep.
Delivery time
After the payment is confirmed, you fill in your child's details using the link we send. The digital product is ready within 24 hours after you send those details.
Payment
Payments are processed by Stripe and charged in US dollars. If your card is in another currency, your bank converts the amount and may charge its own fees. MJ Kids never receives or stores card details.
Changes and refunds
Adjustments: if the character doesn't look like your child or something isn't as you asked, we fix it at no cost. Just email us.
Change of mind: you can cancel within 7 days of payment and we refund the full amount to the same card. With the refund, access to the game and stories of that order ends, including on the devices where they were installed; the parents' area stays available.
To ask for an adjustment or a refund: [email protected], with your order code.
Using the product
The game or story is for personal and family use. The drawings, code and music belong to MJ Kids; the character is made for your family and is not sold to anyone else. We don't use logos, club or player names, or characters from other brands.
Parents' responsibility
Orders are placed by an adult responsible for the child. We recommend using the daily time limit and the night lock that come with the game, and keeping an eye on your child's screen time.
