Privacy policy

Last updated 5 November 2026

Draft. This policy describes how the app is actually built. Have it reviewed by a lawyer for your country (for example India's DPDP Act 2023 and the US COPPA rule) before launch.

The short version

We do not ask for, and do not store, a child's real name, email address, phone number, age, birthday, photo, location or voice recordings.
Each family gets a random key that lives on your device. The key is how the app knows which progress is yours. There is no login and no password.
We store each child's nickname, chosen avatar, settings and chess progress, so progress can sync between your family's devices.
No advertising, no ad trackers, no selling or sharing data for marketing.
You can delete everything at any time from Grown-ups → Family account → "Delete our family's data".

What we store on our server

Family record: a random family id, your price region (for example India or USA), and whether you have an Ollie Pro pass and until when.
Device keys: a one-way fingerprint (hash) of each device's random key. We cannot turn it back into the key.
Progress: nicknames, avatars, settings, lessons finished, puzzle and game results, skill scores, and Brick Builder Math progress (studs, levels, buildings). We keep one copy per day for the last 30 days so a parent can restore an older day.
Email sign-in (optional, for parents): if you add an email and PIN to get your progress back on other devices, we store only a one-way fingerprint (hash) of the email and a salted hash of the PIN. We never store the email itself, cannot read it back, and never send emails.
Usage counts: how many coach answers were used today (for fair-use limits) and simple counters such as "a lesson was finished" with a date. These never include what a child said or typed.
Payments: the payment provider's reference, amount, currency and date. We never receive card, UPI or bank details.

Talking to Ollie

When a child asks Ollie a question, the question text and the chess position are sent to our server and then to Anthropic's Claude API to write Ollie's answer. Voice input is turned into text by the child's own browser; we never receive audio. Ollie is instructed to talk only about chess and learning, never to ask for personal information, and replies are filtered before they are shown. We do not keep the text of questions or answers after the answer is sent. Ollie's spoken audio is cached on our server and deleted automatically after 14 days without use.

Anthropic processes this text under its commercial terms, which do not allow it to train models on API data. Spoken audio for Ollie's voice is made on our own server.

Payments

Payments are handled by Razorpay (India) or Stripe (other countries) on their own pages. Their privacy policies apply to the details you give them.

Cookies and storage

We use your browser's local storage to keep your family key and progress on the device. We do not use advertising or analytics cookies.

How long we keep data

Progress is kept while your family uses the app. Families with no activity for 24 months may be deleted. Payment records are kept as long as tax law requires.

Your choices

Delete all of your family's data in the app at any time. It is removed from our server immediately and from backups within 30 days.
Use the app without the internet; progress then stays only on that device.
Contact us through the support link on our website for any privacy question.

Children

The app is made for children aged 5–12 using it with a parent's permission. Buying and family settings sit behind a grown-up check. Because we do not collect personal information from children, there is nothing that identifies a child for us to share.
