Cookies
Umiko uses a few cookies, all its own, and only to make the site work. There are no advertising cookies and no analytics trackers. Only when you pay does another company, Razorpay, come in.

What a cookie is
A cookie is a small note a website asks your browser to keep, so the site can recognise you on the next page. Without one, you would have to sign in again on every screen.

Kept on your phone, never sent to us
Your browser also remembers a few small things for Umiko. They stay on the phone.
- ai-teacher:muted: Whether the sound is on or off.
- umiko:hidden: Whether the little Umiko helper is tucked away.
- umiko-hello-day: So Umiko asks "How are you today?" only once a day.
- umiko-dinner-asked: Which dinner questions a parent has marked as asked.
- umiko-postcards: Which postcards your child has opened.
- umiko-gifts and umiko-pool-gifts: Which gifts from the deep have been opened.
If you install Umiko as an app, your phone also keeps copies of pictures and styles so it opens faster. It never keeps copies of your family's pages.
When you pay
If you start Umiko Plus, the payment happens in a window run by Razorpay, our payment company. That window may set Razorpay's own cookies to keep the payment safe and to remember your payment method if you ask it to. It opens only when you press the button to pay, never on a child's screen, and it is governed by Razorpay's own privacy policy.
Why there is no cookie banner
Every cookie above is needed for something you asked Umiko to do, and none follows you around the web. If we ever add a cookie that is not strictly needed, we will ask you first.
Turning cookies off
You can clear or block cookies in your browser's settings. Umiko's public pages will still work, but you will not be able to stay signed in. More about what we keep is in the Privacy Policy.
