Privacy Policy
Neuro Sapiens Private Limited
- Last updated: 1 October 2026
- Effective: 1 October 2026
- Version: 1.2
The short version
Nijo is a toy that talks with your child. To do that, it has to listen to them. Here is the honest summary:
| Your child's voice | Streamed to our servers and AI providers to understand and reply. While Nijo is in beta, recordings are stored for 90 days, then automatically deleted. We keep them only to find and fix the toy's mistakes while it is still new. See Section 5. |
| Conversation transcripts | Deleted automatically after 30 days. That is on by default; you can switch it off in Settings if you would rather keep them. You can also delete them yourself at any time, or switch off saving entirely. |
| Nijo's memory of your child | Facts Nijo learns (name, interests, things they mention) are kept for as long as you use Nijo, so it recognises them. Deleted when you say so. |
| Advertising | None. We do not advertise to your child, we do not profile them for ads, and we do not sell anyone's data. Ever. |
| Who else sees it | Only the service providers who run the conversation for us, named in Section 9. No one else. |
| Your control | In the App: turn off saving, delete transcripts, delete Nijo's memory, delete a safety alert, delete your whole account. By email: a copy of your data, deleting a child profile, or anything else - we respond within 30 days. |
The rest of this document is the detail.
1. Who we are
Neuro Sapiens Private Limited, a company incorporated in India, is the Data Fiduciary (under India's Digital Personal Data Protection Act, 2023) for the data described here.
Contact us about anything in this policy at customer@nijostudio.com.
2. Whose data this is about
- You - the parent or guardian who holds the account.
- Your child - who talks to the Device. Your child has no account and never signs in.
We process a child's data only on your consent, which you give in the App after you sign in, before Nijo talks with your child for the first time. See Section 8.
3. What we collect
3.1 From you (the parent)
| Data | Why |
|---|---|
| Your name and email address | To create your account and know it is you |
| Your sign-in details, or your Google account if you choose to sign in with Google | To sign you in |
| Your subscription and payment status | To run your subscription |
We do not collect your phone number. Card details are handled by our payment processor - we never see or store them.
3.2 About your child
| Data | Why |
|---|---|
| First name | So Nijo can address them |
| Age | So Nijo speaks at the right level and applies age-appropriate safety |
| Interests | So Nijo can talk about things they care about |
| Topics to avoid | So Nijo steers away from them |
| Chosen avatar | Cosmetic |
We do not collect your child's date of birth, gender, photograph, contact details, address, or school.
3.3 From conversations
| Data | Stored? |
|---|---|
| Voice audio of your child speaking | Yes - for 90 days, during the beta only. We keep the recording so we can hear what actually went wrong when the toy misunderstands or misbehaves, and fix it. It is deleted automatically after 90 days, or sooner if you delete it. When the beta ends, we will stop storing voice audio and will tell you before that changes. |
| Transcript - the text of what your child said and what Nijo replied | Yes. Deleted automatically once 30 days old - that is on by default, and you can switch it off in Settings. You can delete them yourself at any time. See Section 5. |
| Nijo's memory of your child - what Nijo remembers from their conversations | Yes - until you delete it. See Section 5. |
| Safety alerts, with a short snippet of what triggered them | Yes - for 30 days. They are deleted automatically once 30 days old, and each alert has a delete button so you can remove one sooner. |
3.4 About the toy itself
We record which toy is paired to your account and when it was last online, so we know it is yours and can tell you if it stops working.
3.5 What we deliberately do not collect
- Your location. We ask for location permission only to show you the Wi-Fi networks near you while you set the toy up. We never collect, store, or share where you are.
- Your home Wi-Fi password. It goes straight from your phone to the toy. It never reaches our servers.
- Anything for analytics or advertising. The App carries no tracking tools, no ad tools, and no crash-reporting tools at all.
4. Why we process it, and our legal basis
Under the DPDP Act, our basis is your consent, given on the consent screen in the App after you sign in. We process data to:
- Run the conversation - turn your child's speech into text, generate a reply, speak it back.
- Personalise it - use Nijo's memory so it recognises your child and follows up on past conversations.
- Keep your child safe - automatically scan conversations for concerning topics and alert you.
- Run your account and subscription.
- Keep the Service secure and working - debugging, abuse prevention, error logs.
- Improve Nijo - only as described in Section 6.
We never use your child's data for advertising, ad profiling, or behavioural targeting, and we never sell it. Under the DPDP Act, targeted advertising directed at children and behavioural tracking of children are prohibited, and we do not do them.
5. How long we keep things
| Data | Retention |
|---|---|
| Voice audio | 90 days - during the beta only, then automatically deleted. Kept solely to diagnose and fix the toy's mistakes. This retention exists because Nijo is new; it ends when the beta ends. |
| Transcripts and conversation summaries | 30 days, then automatically deleted - "Auto-delete Transcripts" in Settings is on by default and covers a transcript and the summary made from it together. Switch it off and they are kept until you delete them. |
| Safety alerts and their snippets | 30 days, then automatically deleted. You can delete any alert sooner from the App. |
| Nijo's memory of your child | Until you delete it. It is not deleted automatically, and not deleted if your subscription lapses. |
| Account data (name, email, sign-in details) | While your account exists. |
| Child profile (name, age, interests) | Until you delete the profile, or your account. |
| Device pairing record | While the toy is paired to your account. |
| Security and transaction records | As long as the law requires (e.g. tax, fraud prevention), even after account deletion. |
Memory is the exception, so Nijo keeps knowing your child. You can delete it whenever you want - see Section 7.
6. Improving Nijo
We may use de-identified transcripts - with names and identifying details removed - to measure and improve Nijo's safety, accuracy, and speech recognition.
During the beta, we may also listen to the stored voice recordings described in Section 3.3, to work out why the toy misheard or answered badly. A voice recording cannot be de-identified - it is your child's voice - so we are explicit about it here rather than calling it anonymous.
- We do not use your child's data to train AI models, and we do not want our providers to. We are putting data processing agreements in place with each AI provider that forbid training on your family's data. Until each one is signed, that provider's own terms decide, and Section 9 shows where each one stands.
- You can opt out of your family's data being used for improvement at any time, without losing any feature - just email us. Opting out also stops us storing voice recordings.
- Recordings are never listened to as a matter of routine. Only the staff who need access have it, only to look into a specific safety report or fault, or where the law requires - and every access is logged.
- This is a beta measure. When the beta ends we will stop storing voice audio, delete the recordings we hold, and update this policy - telling you before it changes, as Section 13 requires.
7. Your rights
Under the DPDP Act you have the right to access, correct, and erase your and your child's data, to withdraw consent, and to complain.
In the App you can, at any time:
- Turn off conversation saving - from then on we stop storing the transcript, the conversation summary, the beta voice recording described in Section 3.3, and anything new Nijo would have learned about your child.
- Delete transcripts - wipes the stored conversation text straight away, along with the voice recordings from those conversations.
- Delete Nijo's memory - wipes everything Nijo has learned about your child. Nijo will no longer recognise them or refer back to earlier conversations. This cannot be undone.
- Delete a safety alert - removes the alert and the snippet of speech that triggered it.
- Delete your account - removes your profile, your children's profiles, their transcripts, and their memory, subject to the legal-retention exception in Section 5.
For anything else, email customer@nijostudio.com and we will respond within 30 days:
- Get a copy of your data.
- Delete a child profile.
8. Children - the specifics
- Nijo, the toy, is for children aged 3 to 10. The App is for parents and guardians aged 18 or over. Under the DPDP Act anyone under 18 is a child, so we treat every child who talks to Nijo that way.
- A parent must set Nijo up. A child cannot create an account, cannot subscribe, and cannot sign in to the App. Your child talks to the toy, or on your phone when you start a Talk for them.
- We rely on your consent as parent or guardian to process your child's data. You give it in the App, after being shown what is collected, who processes it and how long it is kept, and you confirm that you are 18 or over and the child's parent or guardian. You can withdraw it at any time in the App under Settings, Profile; Nijo then stops talking with your child until you agree again.
- During the beta, Nijo is available to families in India only.
- We do not knowingly process a child's data without a parent's consent. If we learn a Device was set up by someone who is not the child's parent or guardian, we will suspend it and delete the data.
- No advertising, no ad profiling, no behavioural tracking of children. Not now, not later.
- The alerts feature exists so a parent can supervise their own child. It is not used for any other purpose, and its output goes only to you.
9. Who we share data with
We share data only with service providers who help us run Nijo, and only as far as they need it, to:
- host our servers, database, and storage;
- transport the live voice conversation between the toy and our AI;
- convert your child's speech to text, and Nijo's replies back into speech;
- generate Nijo's replies;
- send notifications to your phone;
- take payment, when you subscribe.
Each of them processes the data only to provide its service to us. We are putting a data processing agreement in place with each AI provider that also forbids training on your family's data; until each is signed, the provider's own terms apply, as shown below.
These are the companies that process your or your child's data for us today:
| Company | What it does for Nijo | What it receives | Where | Training on the data we send |
|---|---|---|---|---|
| Sarvam AI | Turns your child's speech into text; speaks Nijo's replies | Your child's voice; Nijo's replies | India | Its published terms disagree with each other; we are confirming in writing that it does not |
| Groq | Writes Nijo's replies; works out what Nijo should remember | The conversation text, your child's first name and profile, Nijo's memory | United States | Not permitted by its terms |
| OpenAI | Speech to text and replies when the services above are unavailable; conversation summaries; the weekly note | Your child's voice, the conversation text, first name, Nijo's memory | United States | Not used for training by default under its terms |
| Cartesia | Speaks Nijo's replies; learns how to say your child's name; speech to text as a backup | Nijo's replies, your child's name, your child's voice (backup only) | United States | Allowed by its standard terms unless we opt out; we are opting out and putting an agreement in place |
| smallest.ai | Speaks Nijo's replies when the services above are unavailable | Nijo's replies | India | Not permitted by its terms |
| Amazon Web Services | Our servers, database and storage; sign-in code emails | Everything we store; your email address | India (Mumbai) | Not applicable (storage and hosting) |
| Expo | Delivers notifications to your phone through Apple and Google | Your child's first name in the notification text | United States | Not applicable (not stored after delivery) |
| "Sign in with Google"; our email and the forms on this website | Your Google sign-in, and what you send us | Worldwide | Not applicable |
The live voice connection between the toy, the App and our AI runs on our own servers in India; no outside company carries it.
We name every company here and update this list before a new one receives your child's data. If one of the AI services above is unavailable, Nijo uses another one from this list, or stops; it never sends your child's conversation anywhere else.
We also disclose data if the law compels us - a valid court order, or where disclosure is necessary to prevent serious harm to a child. If that happens we will tell you, unless we are legally forbidden from doing so.
If we are acquired or merge, your data may transfer to the acquirer, who will remain bound by this policy. We will notify you first, and you may delete your data before the transfer.
We do not sell personal data. There is no circumstance under which we will.
10. Where data lives
Your data is stored in India.
To let Nijo talk, some of it is handled by the providers described in Section 9, and some of them are outside India. They only ever process it for us - never for their own purposes - and only as much as is needed to generate a reply.
11. Security
- Everything sent between the App, the toy, and our servers is encrypted.
- Access to real user data is restricted to staff who need it, and is logged.
If a breach affects your data, we will notify you and the Data Protection Board of India, as the DPDP Act requires.
12. Cookies and website tracking
This section is about cookies - small files a website stores in your browser. They matter
only on our website (nijostudio.com); the two places your child's data actually lives are
the toy and the App, and neither uses them.
- The App and the toy use no cookies, and no tracking, ad, or crash-reporting tools. Nothing about your child is tracked this way. (This is the same commitment as Section 3.5.)
- Our website uses only the cookies it needs to work - to keep you signed in, remember what is in your cart, and remember your preferences. Without these the site cannot function.
- We use no analytics on our website. No Google Analytics, no tracking scripts, no visitor profiling. If we ever add basic, aggregated analytics to understand which pages are viewed, we will name the tool here first.
- We do not use advertising cookies, we do not track you across other websites, and we do not build ad profiles.
You can block or delete cookies at any time in your browser settings. Blocking strictly necessary cookies may stop parts of the website from working, but it has no effect on the App or the toy.
13. Changes to this policy
We may update this policy. For material changes - especially any change to what we collect from your child, or how long we keep it - we will notify you in the App and by email at least 15 days before the change takes effect, and we will ask for your consent again rather than assume it.
14. Contact and complaints
Neuro Sapiens Private Limited Privacy, data rights, and support: customer@nijostudio.com. Our contact page has a ready-made email for each kind of request.
Grievance Officer: customer@nijostudio.com We acknowledge complaints within 24 hours and aim to resolve them within 15 days.
If you are unsatisfied, you may complain to the Data Protection Board of India.
Want to know exactly which companies process your child's data? They are listed in Section 9. Email us if you have a question about any of them.
We send these providers your family's data only so they can provide their service to us. Section 9 shows, for each one, where its terms stand on training while our agreements are being signed.
