Privacy Policy
Umiko teaches children to use AI well. Because it is for children, it keeps as little as it can, shows the parent everything, and lets you delete it all in one step.
Last updated: 10 November 2026
The short version
- We keep a child's first name and age, and what they do in the app. Nothing else about them.
- We keep no photos of a child, no birthday, no voice recordings, no location and no school name. One exception: a family that joins our small test of how Umiko hears children, and whose parent switches it on for a child, has that child's voice clips kept for 60 days, heard only by the Umiko team, then deleted by themselves; switching it off deletes them at once.
- A parent can read everything their child typed, said or made, and everything Umiko answered.
- No adverts. No tracking for adverts. We do not sell or rent anyone's data.
- A child can only use Umiko after a parent (or, in a school, the teacher) has agreed.
- You can delete your whole family, and everything in it, at any time.
Who we are
Umiko (umiko.online) is run by ADX Studios, Sonipat, Haryana, India. In this policy "we" means ADX Studios, and "you" means the parent, guardian, teacher or grandparent using Umiko. How to reach us is at the end of this page.
Under India's Digital Personal Data Protection Act, 2023, ADX Studios is the "data fiduciary": the one who decides why and how personal data is used, and who answers for it. This policy also covers the Information Technology Act, 2000 and its rules.
Why we are allowed to use it
- Your consent. For everything about a child, we rely on the consent a parent gives before the child starts. The exact words are on the Parental consent page.
- Because you asked. To sign you in, send a code you requested, or add you to the waiting list.
- Safety and the law. To keep a child safe, to stop misuse, and to do what the law requires of us.
What we keep
About a parent
- Your mobile number or email address, whichever you sign in with, and the name you give.
- A record that you agreed to your child using Umiko: which wording you saw and when.
- The settings you choose: your child's language, bedtime, homework help on or off, the morning message.
- A discount code, if you entered one.
- Whether you have Umiko Plus, when it started, what it costs and when it renews. Not your card or UPI details: Razorpay holds those, and we never see them.
About a child
- First name and age (for a school child: first name and class).
- What they do in Umiko: lessons finished, what they typed or said to Umiko and what she answered, the stories and words they made, the treats they fed her and the name they gave her.
- Whether a message was stopped by a safety check, so the parent or teacher can see it.
We never ask a child for an email address, a phone number, a password, a photo of themselves or their birthday. If a child types a phone number, an email or an address, Umiko blocks the message before it goes anywhere.
About a grandparent
- First name, language and, if the family gives it, a WhatsApp number.
- That they agreed, by replying to Umiko's welcome message, and when.
- What kind of message they sent and what Umiko answered. Screenshots and voice notes are read once and not stored.
About a teacher
- Name, email address, a password stored only in scrambled form, and the school and classes.
If you join the waiting list
- The email address or mobile number you typed and, if you gave it, your first name. We use it to tell you when Umiko opens, and for nothing else.
What we use it for
- To teach your child and remember where they are.
- To keep your child safe, and to show you what they did.
- To send what you asked for: a sign-in code, a morning message, a note about your child.
- To fix problems and make the lessons better.
If you tick the optional box "Help make Umiko better", we may keep copies of your child's answers with the name and age removed, to learn which lessons work. This is your choice, you can change it at any time, and it never affects what your child can do.
Children and consent
Umiko is for children aged 5 to 15, used with a parent's knowledge. A child cannot start until a parent or guardian over 18 has agreed, or, in a school, the teacher has confirmed consent for the class. We do not track children across other websites, we do not build advertising profiles, and we show children no adverts. Children are told plainly that Umiko is an AI and not a person.
Who helps us run Umiko
These services handle some data for us. Each gets only what it needs for its job.
| Service | What it gets | Why |
|---|---|---|
| Resend (email)May process outside India | A parent's email address, a one-time sign-in code, and the weekly summary, which holds numbers only. Never a child's name and never anything a child said. | To send a sign-in code to a parent who signs in by email, and the weekly summary to a parent who has it on. |
| Anthropic (Claude AI)May process outside India | What a child types or says to Umiko, with phone numbers, emails and addresses blocked first. Never the child's name or age. A homework photo, once, to read the page. | To write Umiko's answers and to check that questions and answers are safe. |
| Sarvam AIIndia | A short clip of a child's voice, once, to turn it into words. The text of a line Umiko is about to say. | So a child can talk to Umiko and hear her answer. Clips are not kept. |
| ElevenLabsMay process outside India | Umiko's own pre-written lines, recorded in advance. A grandparent's voice note, to turn it into words. | Umiko's recorded voice, and voice notes for grandparents on WhatsApp. It is never used live in a child's session. |
| Meta (WhatsApp)May process outside India | A parent's or grandparent's phone number and the messages sent to and from Umiko on WhatsApp. A child's first name, if the family uses Teach Dadi. | Sign-in codes, updates a parent asked for, and the whole grandparent side. |
| Google (sign-in)May process outside India | Nothing about a child. If a parent chooses "Continue with Google", Google confirms their email address to us. | An easier sign-in for parents. |
| RazorpayIndia | Only when a parent starts Umiko Plus: the parent's name, phone or email, and the card or UPI details they type into Razorpay's own window. Nothing about a child. | Takes the monthly payment. Umiko never sees or keeps card or UPI details. |
| SupabaseMumbai, India | Everything Umiko stores: accounts, children's first names and ages, and what they do in the app. | The database. It is locked so that only Umiko's own server can read it. |
| VercelMumbai, India, with pages delivered worldwide | The requests your browser makes to umiko.online, as any web host does. | Runs the website and the app. |
We share data with nobody else, unless the law requires it or it is needed to protect a child from serious harm.
Where a service works outside India, it handles only what the table says, under its terms for business customers, and only for the job we give it.
What we do not do
- We do not sell, rent or trade personal data.
- We do not show adverts, to children or to anyone.
- We do not track anyone across other websites or apps.
- We do not use a child's work to train AI models.
- We do not let an AI make decisions about a child. More on the How Umiko uses AI page.
Where it is kept and how it is protected
- The database is in Mumbai, India. Some of the services above may process data outside India.
- Everything travels over encrypted connections.
- The database is locked so that only Umiko's own server can read it.
- Sign-in codes and teacher passwords are stored only in scrambled form.
No system is perfectly safe. If something goes wrong that affects your family's data, we will tell you and the authorities as the law requires.
How long we keep it
- For as long as your family uses Umiko.
- When you delete your family, everything in it is deleted at once: the parent, the children, the grandparents, and all they did.
- A family that nobody has opened for two years may be deleted.
- Sign-in codes last ten minutes. A demo child is removed after two days.
Cookies and what stays on your phone
Umiko uses only the cookies it needs to work:
- to keep you signed in (parent, child, teacher), and to remember a phone a parent set up for a child;
- for a few minutes while you sign in with Google;
- to remember a discount code from a link you followed, for up to 30 days.
Your phone also remembers small things for Umiko, such as whether the sound is on and which postcards your child has opened. We use no advertising cookies and no analytics trackers. Every cookie is listed by name on the Cookies page.
Your rights
- See it. The family page shows everything your child did. Ask us for a copy of anything else.
- Correct it. Change your child's name, age or language on the family page.
- Delete it. "Delete my family" removes everything. See Delete your data.
- Take back consent. Untick the optional box, switch off homework help or the morning message, or delete the family.
- Name someone. You may name another adult to use these rights for you if you cannot.
- Complain. Write to us first. We acknowledge within 48 hours and answer within 15 days. See Complaints. You may also complain to the Data Protection Board of India.
Using these rights is free. A child's rights are used by their parent or guardian.
Schools
When a school uses Umiko, the teacher adds the class and confirms that the school holds the parents' consent. The teacher sees what their class does. A school child is known to Umiko only by first name and class.
Changes to this policy
If we change what we keep or who helps us, we will change this page and its date. If the change matters for your child, we will ask for your consent again before it applies.
